Are you feeling that your skin is somehow burning even though you apply sunscreen every day, or that redness and pimples appear repeatedly even though you take the utmost care of your skin? Do you have such frustrating thoughts and feelings? The cause of your endless skin problems may be the effects of ultraviolet rays and the deterioration of your skin's natural defenses.
Many people tend to think that sunburn = spots and freckles, but in fact, UV rays do more than just damage the skin. It directly destroys the skin's barrier function and triggers all kinds of skin problems such as dryness, acne, and itching.
Here, we will thoroughly dissect the scientific mechanisms of why UV rays cause rough skin. In addition, we will explain everything from emergency rescue methods on days when you are inadvertently exposed to UV rays, to fundamental preventive measures to prevent skin problems from repeating themselves, to the option of cosmetic medicine that goes beyond the limits of self-care, all from a professional perspective.

Why do UV rays make skin rough? The real reason causing redness, acne and itching
I am wearing sunscreen every day, but my skin keeps getting rougher and rougher. What am I doing wrong?" Many of you may be sighing in front of the mirror, "What's wrong with my measures?
In fact, the cause of the rough skin may not be as simple as simply inadequate sun protection. The root of the problem lies in the fact that "ultraviolet rays," which are more powerful than we think, are quietly but surely destroying the skin's natural defense system, the "barrier function.
In this section, we will first clarify the true nature of the enemy, ultraviolet rays, and how they trigger all kinds of skin problems, such as "deterioration of the barrier function," and the mechanisms that lead to specific symptoms such as acne and dryness, from a professional point of view. Understanding the "real reasons" for what is happening to your skin is the first step toward finding the root cause.
The true nature of the "two types of UV rays" that attack your skin!
We tend to lump "UV protection" together, but did you know that there are two types of UV rays that have different properties when it comes to our skin: UV-B and UV-A? They are "UV-B" and "UV-A.
(data) item | UV-B (Ultraviolet B Wave) | UV-A (Ultraviolet A) |
---|---|---|
wavelength | short | long (time) |
Depth of reach | Skin surface (epidermis) | Deep in the skin (dermis) |
Effects on skin (short-term) | Redness, tingling, blistering (sunburn) | Darken skin (Santan) |
Effects on skin (long-term) | Risk of spots, freckles, skin cancer | Wrinkles, sagging (photoaging) |
peak period | Around April to September (especially in summer) | Year-round (especially peaks from April to August). Even in winter, there is 1/3 to 1/2 of the peak volume, so caution is required. |
feature | Strong energy. Blocked by glass. | It penetrates clouds and window glass. It is called "living ultraviolet radiation. |
Understanding the difference between the two is fundamental to effective UV protection. Let's take a look at what each one is, how they affect the skin, and how they are related to skin irritation.
UV-B" (sunburn), which causes inflammation on the surface of the skin
UV-B is ultraviolet rays that act mainly on the surface of the skin (epidermis) with strong energy. This is the main cause of so-called "sunburn," a sunburn that occurs when the skin turns bright red and tingles after swimming in the ocean. Because the energy is so strong, it damages the DNA of skin cells and promotes excessive melanin production, which causes spots and freckles.
This rapid inflammation caused by UV-B is one of the factors directly responsible for skin redness and itching. It can truly be said that UV-B ravages the skin's surface with a short-term, concentrated attack.
UV-A" (suntan), which reaches deep into the skin and promotes aging
On the other hand, UV-A has a longer wavelength than UV-B and has the nasty property of penetrating deep into the skin, even through clouds and window glass, to reach the "dermis layer. Although the energy itself is not as strong as that of UV-B, it gradually destroys and denatures collagen and elastin, which support the skin's foundation, and is the biggest cause of photoaging, such as wrinkles and sagging skin.
Also referred to as "ultraviolet rays of daily life," we are continually exposed to these rays without realizing it, and in the long run they deplete the elasticity and firmness of our skin and accelerate the aging of the skin as a whole.
What is the root cause of all skin problems, "deterioration of the barrier function"?
We have told you that there are two types of attacks, UV-A and UV-B. So how do these lead to the specific symptom of "rough skin"? The key to this is our skin's innate defense system, the "barrier function.
When this function is working properly, the skin is not easily disturbed by a little UV light. However, once this barrier is broken down by UV rays, the skin becomes vulnerable to all kinds of stimuli, causing problems such as dryness, redness, and itching.
Healthy skin is protected by the outermost "stratum corneum," which is only about 0.02 mm thick. This incredibly thin layer is the front line in protecting the moisture and health of our skin. The stratum corneum is composed of stratum corneum cells, which are stacked like bricks, intercellular lipids (the main component is ceramide), which fill in the spaces between the stratum corneum cells like cement, NMF (natural moisturizing factor), which holds moisture within the cells, and the sebum membrane, which covers the surface of the skin.
These work in precise coordination to prevent evaporation of moisture from the skin's interior, while at the same time blocking the entry of allergens, bacteria, and physical stimuli from the outside. This is the true nature of the "barrier function.
However, ultraviolet rays, especially UV-B, directly attack this barrier function. UV damage weakens the skin's ability to produce intercellular lipids, especially ceramide, the main component of intercellular lipids, which is the most important factor in maintaining skin moisture. When ceramide, which plays the role of cement, decreases, the bonds between the bricks (stratum corneum cells) loosen, and moisture inside the skin escapes rapidly through the gaps between them.
This is the beginning of dryness. In addition, skin with a broken barrier is extremely delicate. It can easily become red and itchy, reacting to even the slightest irritation, such as cosmetic ingredients, mask friction, and dust in the air, which are normally harmless.
How UV rays cause acne and dryness
The barrier function is reduced and the skin becomes unprotected. There, UV rays trigger a series of more specific skin problems.
Here, we will focus on "acne/pimples" and "dryness/stiffness," which especially bother many people, and take a closer look at how UV rays aggravate these symptoms. Please read on while comparing what is happening to your own skin.
Acne and pimples|Vicious cycle of oxidized sebum and clogged pores
Have you ever felt that "exposure to ultraviolet light makes acne worse?" There are clear reasons for this. First, UV rays cause hyperkeratosis, a thickening of keratin, as a defensive reaction of the skin. The thickened keratin blocks the exit of pores, making it difficult for sebum to be discharged smoothly.
Even more serious is the "oxidation" of sebum itself by ultraviolet rays. UV rays generate "active oxygen," which is harmful to the body, and when combined with sebum, it turns into "lipid peroxide," which irritates pores. This oxidized sebum further aggravates clogged pores and provides the perfect breeding environment for acne-causing bacteria, Acne bacillus.
In other words, UV rays have the double effect of "blocking pores" and "aggravating sebum," triggering and aggravating adult acne and pimples.
Dryness and wrinkling|Evaporation of water and disruption of turnover
Skin dryness and roughness/stiffness to the touch are also typical skin problems brought on by UV rays. As mentioned above, the deterioration of the barrier function caused by UV rays weakens the skin's ability to retain moisture, leading to severe dryness. Skin that has lost moisture becomes less supple and the surface feels hard and rough.
In addition, UV damage disrupts "turnover," the skin's renewal cycle. Healthy skin is generally reborn into new cells in a 28-day cycle (*in the case of people in their 20s), but this rhythm is disrupted when skin is damaged by UV rays. This cycle tends to lengthen with age, and in people in their 40s, it can take more than 40 days.
Old keratin, which should normally be peeled off, accumulates on the surface of the skin and forms a thick layer. This is the true cause of rough and dull skin. Skin with disturbed turnover tends to fall into a vicious cycle in which even if you go to the trouble of moisturizing with lotion, the active ingredients are less likely to penetrate the skin, making it difficult to feel the effects of your care.
What is the proper way to take care of yourself on a day when you have been exposed to UV rays?
In the previous section, we reported how ultraviolet rays destroy the skin's barrier function and cause skin irritation. We hope you now understand how scary this can be, but no matter how careful we are, we all have days when we feel we have been exposed to ultraviolet rays longer than usual.
With red, flaming skin, you may feel impatient, anxious, and confused, "Where do I start?" You may be confused and anxious about what to do first. But don't worry. The care you take on the day you are exposed to ultraviolet rays will greatly affect your skin in the future.
Here is a detailed step-by-step "Emergency Action Manual" to minimize skin damage and prevent serious skin irritation. Once you know the correct first aid measures, there is no need to panic anymore.
Could that care be counterproductive? First of all, you need to know the ironclad rules of NG behavior and correct first aid.
Immediately after exposure to ultraviolet rays, the skin is in an extremely delicate state, as if it has been slightly burned. In many cases, hasty care at this time can worsen inflammation and aggravate skin problems such as blemishes and dryness.
We must do something about it as soon as possible!" But first, let's take a breath and make sure we know what NG care we should not do.
- Scrubbing face and hot shower: Friction is the greatest enemy that aggravates inflammation. Hot water also deprives the skin of necessary sebum, contributing to dryness.
- Forcibly remove the flaked skin: Even if you are concerned about it, never force it off. The golden rule is to wait for the skin to peel off naturally. This can damage the immature skin and cause hyperpigmentation.
- Crushing a blister: Blisters are like a natural bandage that protects injured skin and prevents infection. If you crush them, you greatly increase the risk of bacteria entering the area, causing festering and scarring.
- Applying oily cream abruptly: Applying oily cream when the skin is hot may cause heat buildup and prolong the inflammation.
- Self-judgmental use of medications: It is very dangerous to use over-the-counter medications that do not match the symptoms, especially concentrated steroids, on one's own judgment.
- Use of sheet masks and whitening cosmetics: Whitening and anti-aging ingredients can be irritating to inflamed skin, so avoid them now.
The ironclad rules of first aid after sunburn are (1) cool the skin anyway and (2) moisturize thoroughly. First, extinguish the "fire" of skin inflammation by cooling, and then support the repair of the broken barrier function by thoroughly moisturizing. Making no mistake about this order and purpose is the shortest route to regaining healthy skin.
STEP1|Cooling】To soothe inflammation, the first priority in first aid treatment.
If your skin is burning or reddening after exposure to UV rays, it is a sign that your skin is "inflamed". Calming this inflammation as quickly as possible is the first priority in first aid. Cooling not only relieves redness and pain, but also prevents the spread of damage and inhibits the over-activation of melanocytes, which cause blemishes.
The easiest and safest method is to gently apply a clean towel wet with cold water to the skin. When the towel becomes lukewarm, cool it again and apply it repeatedly.
For more firm cooling, use of a coolant or ice pack wrapped in a towel can also be effective. However, never apply the coolant directly to the skin. There is a risk of frostbite. Always wrap it in a dry towel and keep it to the extent that it feels "cool and comfortable. Instead of applying it to one spot continuously, cool the entire face evenly, shifting the location little by little, for about 10 to 15 minutes.
It is wise to take a quick shower with lukewarm water (32-34°C) and avoid taking a hot bath on this day. When washing the body, do not scrub the body with a nylon towel, but rather gently stroke the body with plenty of lather.
STEP2|Cleaning: Friction is strictly prohibited! How to use "foam face wash" to protect damaged skin
Once the skin is cooled and the burning sensation has subsided slightly, the next step is to gently wash off any remaining sunscreen, sweat, and sebum on the skin. However, the skin is still very sensitive at this stage. The barrier function has been reduced, so it is important to remember that even the slightest bit of friction can cause serious damage. Rather than "removing dirt," the top priority should be to "wash while protecting the skin.
First, choose a cleanser that is labeled "hypoallergenic" or "for sensitive skin. We recommend those containing amino acid-based cleansing ingredients with mild cleansing power. On the other hand, facial cleansers with scrubs (particles) or those with a peeling action should never be used because they are too irritating to the skin.
STEP3|Moisturizing: Deliver moisture thoroughly and support the skin's ability to recover.
After cooling to soothe inflammation and gently rinsing, the skin is in a "naked" and unprotected state. This is the "golden time" for moisturizing, when the moisture in the stratum corneum is most likely to evaporate.
The speed of skin recovery depends greatly on how much high quality moisture is delivered here. Apply a lotion with plenty of moisture, and then use a milky lotion or cream to lock in that moisture.
How to choose and use lotion
Choose a lotion that is hypoallergenic with the simplest possible formulation, such as alcohol (ethanol)-free, fragrance-free, and colorant-free. It is more effective if it contains "ceramide," which supports the restoration of the barrier function, "hyaluronic acid" and "collagen," which have high water retention capacity, and "2K glycyrrhizate" and "allantoin," which are expected to reduce inflammation.
Cotton fibers can be irritating, so take a 500-yen coin-sized amount on a clean hand and hand-press it gently over the entire face. The key is not to apply too much at once, but to divide it into several times and let it penetrate slowly.
Always "cover" with milky lotion/cream
Moisture given with lotion will quickly evaporate if left untreated. The final step in moisturizing care is to apply a "lid" with an oil such as milky lotion or cream to prevent moisture from evaporating. Choose a low-irritant product and apply a non-sticky amount (about the size of a pearl or two) to your hands and gently smooth it over the entire face.
It is also a good idea to apply a layer around the eyes and mouth, where dryness is particularly important. This careful moisturizing care will powerfully help restore the damaged skin barrier function.
No more repeats! Preventive measures to grow skin that can resist UV rays
Knowing how to properly care for your skin after it has been exposed to ultraviolet rays, should you be exposed to them, is very important to protect your skin. However, the ideal of skin care is to avoid causing skin problems in the first place. It is because of this desire that many people apply sunscreen every day.
Why does it still cause skin irritation?" The answer may lie in the way we choose and use sunscreen, and in the way we think about UV protection itself. Here, we provide a thorough explanation of a "solid defense strategy" that is not a stopgap measure, but is designed to break the skin damage caused by UV rays at its root.
How to choose and use sunscreen to maximize its effectiveness
The mainstay of UV protection is sunscreen. However, simply selecting and applying a high SPF value product in the dark is not enough to fully demonstrate its effectiveness.
Select a bottle that best suits your skin type and the situation of the day, and practice "correct dosage" and "frequent reapplication. Only when these three elements are in place will sunscreen become the strongest shield against UV skin irritation.
(1) By scene and skin type
First, let's review the meaning of "SPF" and "PA" on sunscreen packages: SPF indicates the duration of protection against UV-B, which causes redness and irritation of the skin; the higher the number, the more effective; PA indicates the degree of protection against UV-A, which causes wrinkles and sagging, by the number of "+"; and the maximum number of "+" is four. There are four levels, with the maximum being "++++".
- Daily life (commuting to work or school, shopping in the neighborhood, etc.): For days spent indoors for long periods of time, SPF 20-30 and PA++ are sufficient, as they are less stressful on the skin.
- Light outdoor leisure activities (walking in the park, watching sports, etc.): SPF 30-40, PA+++ approx.
- Leisure activities under the hot sun (swimming, mountain climbing, golf, etc.): In environments with extremely strong UV rays, the highest level of protection, such as SPF50+ and PA++++, is essential. Choose a "water-proof" type, as it is difficult to remove with sweat or water.
There are two main types of sunscreens, depending on the mechanism by which they protect against UV rays.
- Ultraviolet absorber: A chemical mechanism that absorbs ultraviolet rays and converts them into other forms of energy, such as heat, before releasing them. These are often found in gel-type products and are characterized by their transparency and resistance to whitening. In rare cases, however, this chemical reaction can cause irritation and skin irritation.
- UV scatterers: Powders such as titanium dioxide and zinc oxide physically reflect and scatter UV rays to protect the skin. Because they are less harsh on the skin, we recommend that those with sensitive or acne-prone skin choose this one, which is described as a "non-chemical formula" that does not contain UV absorbing agents.
(2) How to extract 100% from the effect
No matter how expensive and highly functional sunscreen is, if it is used incorrectly, its effectiveness will be halved. The important points are "the amount used" and "reapplication.
When applied to the face, the appropriate amount is considered to be "two pearls for the cream type, or a 500-yen coin size for the liquid type. This is the amount needed to apply "2mg per 1㎠ of skin," which is the international standard for measuring SPF values, and may seem larger than the amount most people usually use. If the amount is too small, you will not get the full UV protection effect indicated.
In addition, the effect of sunscreen is not permanent. It will fall off unnoticed due to perspiration, sebum, and friction caused by masks or touching the face with the hands. Therefore, it is not an exaggeration to say that frequent reapplication of sunscreen every 2 to 3 hours is the most important measure against UV rays.
Raise the skin's defenses. Eating UV Protection" and Lifestyle Habits to Start Today
In addition to the "defense from the outside" we have discussed so far, it is also essential to take an inner care perspective to "nurture skin from the inside" to prevent skin from being repeatedly damaged by ultraviolet rays. Let's improve the skin's natural defenses by adopting a diet that neutralizes active oxygen, a substance that causes aging in the body due to UV rays, and a lifestyle that enhances the skin's ability to repair itself.
Eating UV protection" to protect skin with antioxidant properties
Actively taking nutrients with strong "antioxidant" properties that remove active oxygen can protect the skin from the inside out.
- Vitamin C: The king of beautiful skin that suppresses melanin production and aids in collagen production. Due to its heat-sensitive nature, fruits and salads eaten raw are more efficient.
- Foods rich in: red and yellow bell peppers, broccoli, kiwi fruits, citrus fruits, etc.
- Vitamin E: Also known as the "rejuvenation vitamin," its strong antioxidant power prevents cell oxidation. It also promotes blood circulation. Its effects are further enhanced when taken together with vitamin C.
- Foods rich in: almonds and other nuts, avocado, pumpkin, eel, etc.
- Lycopene, beta-carotene: pigment component of the red color of tomatoes and the orange color of carrots (carotenoids). It has very strong antioxidant properties. Absorption rate increases when taken with oil.
- Foods rich in: tomatoes, watermelon, carrots, spinach, etc.
- Polyphenols: A general term for components produced by plants to protect themselves. There are many types, including anthocyanins in blueberries, catechins in green tea, and isoflavones in soybeans.
If you still can't get better... the "radical treatment" option available at a cosmetic dermatologist.
So far, we have introduced a variety of self-care techniques for preventing and dealing with skin damage caused by UV rays. If you continue to take good care of your skin on a daily basis with correct knowledge, your skin will surely respond to your efforts.
However, "Even if I take all possible measures, I still get pimples repeatedly," or "The spots and redness on my skin that have accumulated over the years just won't improve..." There are probably some people who are deeply troubled by such problems, feeling that they cannot overcome the obstacles they face through self-care alone. Perhaps, by seeking the help of a specialist, you may be able to find a solution to your deep-seated skin problems.
Here, we detail a new option beyond self-care: "radical treatment" at a cosmetic dermatologist. Let's put an end to your long-standing skin problems.
Critical Differences between Self-Care and Cosmetic Medicine
Many of you may feel that "cosmetic medicine is a hurdle," or "what's the difference between that and self-care?" Many people may feel that "cosmetic medicine is too hard" or "what is the difference between it and self-care? The most critical difference between the two is the "depth" of the skin that can be approached. This is not to say that one is better than the other, but that each has a different "role" to play.
Self-care is "defensive care" to protect the skin's surface
According to the Pharmaceutical Affairs Law (former Pharmaceutical Affairs Law), cosmetics such as lotions and serums that we use on a daily basis are only effective up to the "stratum corneum," the outermost layer of the skin. Their main role is to support the barrier function by moisturizing the skin surface and "protecting" the skin from external stimuli such as dryness and UV rays.
In other words, self-care is protective care aimed at "prevention" and "maintenance," so to speak, in order to prevent future skin problems and maintain healthy skin conditions.
Cosmetic medicine is an "aggressive treatment" that rebuilds the skin from the inside out.
On the other hand, cosmetic medicine performed at cosmetic dermatology clinics, under the supervision of a physician, uses medical equipment and drugs to work directly on the internal tissues of the skin, such as the epidermis and dermis, deeper than the stratum corneum, which are unreachable by self-care.
This makes it possible to improve and rebuild the skin texture itself by destroying melanin, which is the cause of blemishes, improving firmness by stimulating collagen production, and normalizing disrupted turnover. It can be called an "aggressive treatment" that approaches the root causes of problems that have already occurred and leads the skin to a better state.
It is an option that is distinct from self-care in terms of speed of effect, sustainability, and problem-solving ability.
What's Best for Your Skin Roughness? Typical cosmetic treatments for UV damage
Cosmetic dermatology offers a wide variety of treatments, but here we introduce three typical treatments especially for those who suffer from "UV-induced skin irritation.
What symptoms does each treatment method help, and what is the estimated downtime (recovery period) and cost? Please use this information as a reference to find the best option for your skin problems.
Light therapy (IPL)
Intense Pulsed Light (IPL) is a treatment method that irradiates the skin with a special light that is a bundle of light of various wavelengths. This light reacts only to the targets that cause problems, such as melanin, which causes blemishes, and hemoglobin, which causes redness, and damages them.
At the same time, the heat energy reaches deep into the skin (dermis layer) and promotes collagen production. Therefore, not only can multiple problems such as freckles, redness, and dullness be addressed simultaneously, but overall skin elasticity, luster, and texture can also be improved. The fact that there is almost no downtime is also a major attraction.
Chemical peeling
This treatment restores the normal cycle of skin turnover (rebirth) that has been disrupted by UV damage. Special agents such as fruit acids (AHA) and salicylic acids (BHA) are applied to the skin to gently dissolve and remove dead skin cells that have accumulated on the surface.
This unclogs pores and improves acne and acne scars. In addition, the production of a new stratum corneum is stimulated, which leads to a smoother texture and eliminates roughness and dullness of the skin.
Electroporation
Electroporation is similar to conventional ion implantation in that it uses the power of electricity to penetrate active ingredients, but electroporation uses a completely different principle. By applying special electrical pulses to the skin, minute pathways (pores) are temporarily created between cells, through which active ingredients are directly delivered deep into the skin.
The greatest feature of this treatment is that it can introduce high-molecular weight beauty ingredients such as hyaluronic acid and collagen, which are difficult to penetrate using ion implantation. It is also called "mesotherapy without needles," and it is completely painless and causes no downtime. It can be used to soothe inflammation after sunburn, support the barrier function, and prevent skin blemishes. It can also be combined with other laser treatments to further enhance the therapeutic effect.
For beautiful skin you won't regret! 3 Ironclad Rules for Choosing a Beauty Clinic
Cosmetic medicine is a powerful ally that can lead you to a solution to your skin problems. However, in order to maximize its effectiveness and obtain truly satisfying results, it is of utmost importance to find a clinic and doctor you can trust.
Instead of choosing a clinic solely because it has expensive state-of-the-art equipment or is well-known, be sure to check the following three points to determine the clinic that will be the best partner for you.
Will the doctor counsel me directly and carefully?
The initial consultation is extremely important. Do not leave it up to the counselor. Make sure that the doctor examines your skin directly and listens to your concerns and wishes in a friendly manner.
You can trust a doctor who takes your skin type and lifestyle into consideration, proposes several optimal treatment options, and explains the advantages and disadvantages of each in an easy-to-understand manner.
Can you honestly explain the risks and disadvantages?
Even the best treatment has risks such as limited effectiveness, downtime, and side effects. Be wary of clinics that emphasize only good things and hide unfavorable information.
Whether or not the clinic is honest and truthful in explaining possible risks and what to do if the treatment is not suitable is a major indicator of the clinic's attitude.
Is the fee structure clear and does the company have a good after-sales service?
It is essential that the fee structure be clear and easy to understand, and that there be no additional fees such as consultation fees or drug costs other than the proposed treatment fee.
Also, be sure to check in advance whether the clinic has a follow-up system in place to monitor your progress after the procedure and to respond to any skin problems that may arise. Choose a clinic that will take responsibility for looking after your skin until it stabilizes, rather than just performing the procedure and calling it a day.
summary
Here, we have provided a comprehensive explanation of the mechanisms by which ultraviolet rays cause rough skin, as well as specific countermeasures. We hope you now understand that ultraviolet rays include UV-B, which causes inflammation on the skin's surface, and UV-A, which damages the skin deep down, and that these destroy the skin's "barrier function," which is the root cause of all problems such as redness, acne, and dryness.
First, try practicing "cooling" and "thorough moisturizing" on the day of exposure to UV rays, followed by "correct use of sunscreen (amount and reapplication)" and "inner care" from the next day. Just by thoroughly taking care of these basics, the condition of your skin will change drastically.
However, if you continue to see no improvement after self-care, or if you want to improve your skin from a more proactive standpoint, we recommend that you consider the option of "radical treatment" at a cosmetic dermatology clinic. Under the diagnosis of a specialist, professional procedures such as phototherapy and chemical peels are the surest shortcut to resolving skin problems.
UV rays are not an enemy to be feared, and with proper understanding and appropriate countermeasures, it is quite possible to maintain healthy skin. We hope this article will help you protect your skin and live a confident life.
