I want to do something about my smile lines! What are their characteristics and the reality of the problem?

When we look in the mirror, we suddenly notice "laugh lines. These lines, which become more noticeable as we age, greatly affect the impression of our face and tend to be a source of concern. However, these lines may not be a mere "aging phenomenon.

Even young people can be bothered by them, and there are many hidden causes behind them. Here we will discuss in detail the basic characteristics of the laugh lines and why we are bothered by them.

Characteristics of Lines｜Where they are noticeable and how they affect appearance

Lines appear from the sides of the nose to the corners of the mouth and are medically called nasolabial folds. Although they may seem simple at first glance, the presence of these lines can greatly affect the overall impression of the face, sometimes accentuating negative impressions such as "old" or "tired" looks. In particular, since the mouth is a part of the face that easily draws the eye, prominent lines often make the face appear saggy and older than it really is.

So why do lines form? In most cases, the main causes are sagging skin and deterioration of facial muscles due to aging. In fact, however, there are cases in which even younger people are concerned about lines, and there are several factors behind them.

For example, if a person has a lot of fat in the cheeks, the weight of the fat tends to lower the skin, making the lines more prominent. If a person has a habit of repeating certain facial expressions in daily life, the muscles in that area are used exclusively, and the skin is more likely to become furrowed. In addition, dry skin and damage caused by ultraviolet rays cannot be overlooked. As the skin loses its elasticity and firmness, it loses its support and the lines become deeper.

Thus, lines can be caused not only by aging, but also by fat weight, lifestyle, and skin conditions. Because they can appear regardless of age, it is important to understand the causes and start taking care of them as early as possible.

Problems with lines can affect your appearance.

While some may think, "I don't care about lines," the reality is that many people feel their effects very strongly. As mentioned above, lines can look like "facial borders," dividing the cheeks and mouth area. As a result, the three-dimensionality of the face is impaired, giving the impression of sagging. Furthermore, the deeper the lines are engraved, the stronger the tendency to look "old" or "tired.

Changes in appearance can also lead to psychological stress. Many people experience anxiety and low self-confidence about how they look to others and whether or not they look old enough.

 

Why do lines form in the first place? Main Causes Explained

Lines, which greatly affect the impression of the face, are not just a sign of age. As mentioned in the previous chapter, lines can appear even in young people, depending on their lifestyle and skin condition.

So why do lines form in the first place? The causes are a complex combination of various factors, including skin structure, aging, lifestyle, and even the deterioration of facial muscles. Here, we will explain the main causes of the formation of lines in an easy-to-understand manner.

Skin structure and effects of aging｜Decrease in collagen and elastin

Our skin consists of three layers: epidermis, dermis, and subcutaneous tissue. Of these, the dermis plays an important role in maintaining skin elasticity and firmness. The dermis layer is rich in collagen and elastin fibers, which provide the skin with firm support.

However, these components gradually decrease with age. As collagen decreases, the skin loses its firmness, and as elastin deteriorates, it loses its elasticity and the skin begins to fall due to gravity. As a result, the appearance of lines becomes more noticeable.

Skin condition	affect
Decrease in collagen	Loss of skin elasticity
Elastin degradation	Reduced elasticity and tendency to sag
Decrease in hyaluronic acid	Prone to dryness and wrinkling

These changes accelerate in the late 30s and become even more pronounced in the 40s and 50s. This is why age-appropriate skin care is essential.

Influence of lifestyle｜Ultraviolet rays, smoking, lack of sleep, etc. age skin.

Aging is not the only cause of the formation of lines. The influence of our daily lifestyle on our skin is also a point that should not be overlooked. In particular, our casual activities such as ultraviolet rays, smoking, and lack of sleep can cause our skin to age without us noticing, making lines more noticeable.

cause	Effects on skin	Effect on laugh lines
ultra-violet rays	Destruction of collagen and elastin, dryness	Decreased skin elasticity, deeper wrinkles and lines
smoking	Deterioration of blood flow, nutritional deficiencies, and reduced skin regeneration	Sagging skin, loss of firmness, and wrinkles
lack of sleep	Disturbances in the skin turnover (regeneration) cycle	Skin elasticity decreases, lines and sagging progresses
malnutrition	Difficulty in maintaining healthy skin due to lack of necessary nutrients	Skin becomes lackluster and lines worsen.

First, damage to the skin caused by UV rays is extremely serious. Prolonged exposure to UV rays causes a phenomenon called "photoaging" inside the skin. Photoaging is a phenomenon in which UV rays affect the dermis layer, destroying collagen and elastin. This causes the skin to lose its elasticity and become loose and flabby, resulting in the deepening of lines. In addition, UV rays also cause skin to dry out, creating a vicious cycle that makes wrinkles and lines more visible.

Second, smoking is also a major enemy of the skin. Nicotine and other toxic substances in cigarettes constrict blood vessels, preventing the skin from receiving sufficient oxygen and nutrients. This reduces the skin's ability to regenerate itself and inhibits the production of collagen and elastin. As a result, smokers' skin tends to age more easily, and lines and wrinkles tend to deepen. To maintain beautiful skin, quitting smoking is one of the first measures you should take.

In addition, sleep deprivation and nutritional deficiencies should not be overlooked. Sleep is an important time for maintaining normal skin turnover (regeneration cycle). When sleep is in short supply, skin cell renewal is delayed and the skin loses its firmness and elasticity. An unbalanced nutritional diet also causes a lack of necessary ingredients for the skin, making it difficult to maintain healthy skin. Adequate sleep and a nutritionally balanced diet are essential for building the skin's basic strength and preventing lines.

Thus, UV rays, smoking, and lack of sleep can erode skin health and cause lines. However, these are also points that can be improved with daily awareness. Just by reviewing our daily habits a little, we can restore the youthfulness of our skin and prevent or improve the appearance of lines.

Weakening of facial muscles｜Sagging skin due to stiffening of facial muscles

Facial muscles, or "facial muscles," play an important role in making us smile and express ourselves. However, if we repeatedly use the same facial expressions in our daily lives, the muscles used become unbalanced and the entire facial musculature deteriorates.

As the facial muscles weaken, the face becomes less supportive and the skin and fat drop. In particular, as the cheek muscles relax, lines become more visible.

In addition, people today spend more and more time without facial expressions due to desk jobs and smartphone use. This also accelerates the deterioration of facial muscles and causes sagging of the entire face.

 

You can do it at home! How to Prevent and Improve Lines

We explained in the previous chapter that laugh lines are created by a combination of factors, including aging, lifestyle, and deterioration of facial muscles. However, there is no need to give up. You can prevent and improve the appearance of laugh lines through care, exercises, and lifestyle changes that you can easily implement in your daily life. Here, we will introduce in detail methods that you can start right away at home.

What are the key points of daily care? Thorough UV protection and moisturizing

The basics of preventing lines are to prevent skin "dryness" and UV damage. Dry skin makes fine lines and wrinkles more visible, while UV rays destroy collagen and elastin, robbing the skin of its elasticity.

Ultraviolet rays fall all year round. Since UV rays continue to damage the skin not only in summer, but also in fall, winter, and on cloudy days, daily UV protection is essential. It is advisable to check the SPF and PA values of sunscreens and choose SPF30 and PA+++ for daily use. If you spend a lot of time outdoors, choose a sunscreen with SPF 50. Also, reapply frequently, not only in the morning, but every 2 to 3 hours to maintain its effectiveness.

In addition, protecting the skin's moisture as a moisturizing care is also a key to preventing lines. Moisturizing is important to maintain skin elasticity and prevent lines from worsening due to dryness. In particular, choosing a moisturizer containing hyaluronic acid or ceramide will help keep the skin hydrated.

For example, we recommend moisturizing with toner and milky lotion immediately after washing the face and intensive care with a sheet mask once or twice a week.

Facial exercises to strengthen facial muscles!

Weakening of the facial muscles is one of the major causes of the appearance of lines. In everyday casual life, facial muscles become tightened without being used, causing the skin and fat to drop due to gravity. However, by consciously exercising the facial muscles, you can strengthen and tighten them and prevent sagging skin. There are exercises that you can easily work on at home, so try incorporating them into your daily routine.

First, I would like to recommend the "Aieo Exercise. This exercise is expected to strengthen and balance the muscles of the entire face. The exercise is simple: just pronounce the words "A, I, U, E, O" clearly while moving your mouth widely. By continuing to do this exercise every day for five times per set, you can tighten your facial muscles and prevent or improve the appearance of lines.

The next exercise to include is the "balloon exercise. This exercise involves inflating the cheeks to stimulate the facial muscles properly. To do this, first close your mouth and hold in air, then slowly move the air in the order of left cheek, right cheek, upper lip, lower lip, and then the entire mouth. Repeating this exercise five times is all it takes to strengthen the muscles of the entire face in a well-balanced manner and prevent sagging.

Lifestyle Review! Care from the inside out with sleep and food

Your daily lifestyle influences the health of your skin. By being conscious of eating a nutritionally balanced diet and getting enough sleep, you can support your skin from the inside out and prevent or improve the appearance of lines.

nutrient	effect	Foods Containing
vitamin C	Aids in collagen production	Citrus fruits, kiwi, bell peppers
vitamin E	Promotes blood circulation and prevents skin aging	Almonds, avocado, pumpkin
protein	Important as material for skin cells	Chicken, eggs, soy products

The above are the nutrients necessary for skin elasticity and firmness, but be proactive in incorporating the nutrients necessary to maintain skin elasticity and firmness. Adequate sleep also helps to regenerate the skin. During sleep, growth hormones are secreted and skin turnover (regeneration) is stimulated. It is important to try to get 7-8 hours of good quality sleep, and as a bedtime routine, avoid blue light from smartphones and computers and create a relaxing environment.

 

Improve your smile lines with the help of cosmetic medicine! What is the latest treatment for laugh lines?

Prevention and improvement through daily care and exercises described in the previous chapters are effective through daily accumulation. However, you may feel limited by lines that have already been deeply engraved or by sagging skin due to aging.

This is when you can count on the power of cosmetic medicine. In this section, we will explain in detail the features, effects, and risks of the latest injectable and lift-up treatments, and give you pointers on how to choose the method that is right for you.

Easy to take! Hyaluronic Acid and Botox for Injection Treatment

Injection therapy is a very popular method of treating laugh lines because it is quick and requires little downtime. Hyaluronic acid is an ingredient that exists in the body to keep the skin moist and supple. By injecting hyaluronic acid directly into the lines, the grooves are pushed up from the inside, creating a fuller, more plump appearance.

The greatest appeal of hyaluronic acid injections is their "immediate effect. It is easy to feel the effects immediately after the procedure, and the ability to put on makeup and return to one's daily life immediately is a major advantage. However, the effects are temporary, and the body absorbs the substance in about 6 months to 1 year, so regular treatments are necessary. In addition, excessive injections or treatment by a physician with poor technique may result in unnatural-looking results, so care must be taken.

Botox, on the other hand, is a treatment that relaxes the facial muscles that cause wrinkles and sagging by inhibiting muscle movement. It is particularly effective when the muscles around the mouth cause prominent lines. The effect is short-lived, lasting from 3 to 6 months, but in some cases, repeated treatment relaxes the muscles' habits and gradually prolongs the effect.

Lift-up treatment for reliable care! Thread lift and HIFU

When sagging is the cause of prominent lines, a lifting treatment that raises the skin from the roots is effective. One of the most common treatments is a thread lift. The thread lift is a treatment in which special medical threads are inserted under the skin to physically lift sagging skin. In addition, the process of dissolving the threads promotes collagen production, which can be expected to restore elasticity and firmness to the skin.

The appeal of a thread lift is its immediate effect and natural-looking result. However, the effects are not permanent, lasting only one to two years, and swelling and internal bleeding may occur immediately after the procedure. In addition, the choice of physician is important because the results depend on the technique of the procedure.

HIFU, on the other hand, is a treatment that uses high-density focused ultrasound to deliver heat energy to the "SMAS fascia" deep within the skin to tighten sagging skin. Because it is a cosmetic skin procedure and does not use a scalpel, there is little downtime, making it easy for busy people to undergo this treatment.

The effects of HIF are more gradual, appearing about a month or so later than immediately after the procedure. The tightening of the skin's internal structure allows for a natural lifting effect, but the effect may be limited for deep lines.

Lines are caused by a combination of multiple factors, including aging, lifestyle, and deterioration of facial muscles. The important thing is to take appropriate measures in a way that suits you. Continuing with daily care and facial exercises, while seeking the help of cosmetic medicine as needed, will result in more effective improvement.
