Liposuction is gaining popularity as a procedure that can help to improve body contours in a short period of time, but on the other hand, many people are concerned that it leaves scars or that the scars do not disappear forever.
While redness, lumps, and hyperpigmentation that appear after surgery are, to some extent, medically expected, prolonged or conspicuous scars may require medical attention. Understanding the cause of the problem and taking appropriate measures are indispensable in order to avoid the complex effects of a cosmetic procedure.
Here, we provide comprehensive explanations from a professional perspective on the types of scars left after liposuction, their causes, how to determine whether they are normal or abnormal, treatment methods according to symptoms, and how to select a reliable clinic. We provide information based on medical evidence so that those with concerns can make future decisions with peace of mind.

Why do scars remain after liposuction? Three Medical Causes and Symptom Categories
After undergoing liposuction, many people are satisfied with the changes in their appearance, but at the same time they are concerned about the scars and lump-like hardness that remain. In particular, symptoms such as redness, swelling, and uneven coloration that appear some time after the surgery are difficult to judge by oneself as to whether they are normal or abnormal.
However, many of these are temporary reactions that occur as the body repairs wounds, and with proper knowledge there is no need to panic. On the other hand, there may be hidden signs of abnormality that should not be left unattended.
Here, we will carefully explain the types of "marks" that can occur after liposuction, their medical mechanisms, the patterns of progression according to the time of occurrence, and checkpoints to distinguish normal from abnormal from a professional perspective.
Types｜What are hypertrophic scars, hyperpigmentation, and contractures?
Liposuction is a procedure in which a cannula (suction tube) is inserted under the skin to remove fat. This process causes physical damage to the skin and underlying tissues, and postoperative reactions may include the following
(1) Hypertrophic scar
Scars are red, raised postoperative scars. It is caused by excessive collagen production, and is also related to frictional irritation and constitutional factors. It may disappear spontaneously, but if it does not improve after a certain period of time, treatment such as steroid injections may be considered.
(2) Post inflammatory hyperpigmentation (PIH)
A condition in which melanin is deposited after skin inflammation, resulting in a darkened or brownish appearance. Postoperative exposure to ultraviolet light is an aggravating factor, so sun protection is essential. Reduction is expected with topical whitening agents and laser treatment.
(iii) Contracture
A phenomenon in which the fat-suppressed space becomes adherent and the skin becomes tight and hard. It may be felt as an unevenness or lump, but most cases show a tendency to improve within 6 months after surgery. If symptoms are severe, regenerative treatments such as POTENZA may be considered.
Symptoms at different times｜Pattern of progress from 1 week to 6 months after surgery
The marks after liposuction change over time. Proper knowledge of the progress can be a source of reassurance and help to identify signs of concern.
| postoperative period | Main Symptoms | medical interpretation |
|---|---|---|
| 1-2 weeks after surgery | Redness, swelling, mild stiffness | Natural response as an inflammatory reaction |
| 2 weeks to 1 month after surgery | Scar formation and hyperpigmentation surface | Part of organizational restructuring |
| 1-3 months after surgery | Contractures, lumps, and uneven coloration are easily visible. | Effects of temporary adhesions |
| 3-6 months after surgery | Gradually lessens, but if it remains strong, it is abnormal | Need to consider medical consultation |
Most symptoms resolve spontaneously, but if there is no improvement beyond 6 months, some abnormality may be involved.
Normal vs. abnormal] Warning signs to recognize
Although "liposuction scars" are difficult to judge for oneself, the following symptoms are signs of abnormality and should be closely examined by your doctor.
- Reddish-black raised scars that do not improve for more than 6 months
- Hard lumps that are enlarged or painful
- Skin tightness is evident due to contractures, affecting range of motion.
- Dark pigmentation, no change with topical medications
See a specialist immediately, especially if your quality of life is being interfered with or if you are experiencing emotional stress.
To avoid scarring｜Care and medical measures to be taken before and after liposuction
In the previous chapter, we looked in detail at the types of "scars" that remain after liposuction, their progression, and abnormal signs to watch for. So what can we do to minimize these scars and make them as beautiful as possible?
The key to success is proper care before and after surgery. Successful liposuction is not only a function of the physician's skill, but also of the patient's preparation and recovery period. This section provides a detailed explanation of the medical measures and daily care necessary to prevent and minimize liposuction scars, based on medical evidence.
Preoperative Preparation] Design of cannula and treatment area is key.
In liposuction, an instrument called a cannula is inserted through the skin to remove fat. Although the incisions made during this process are very small, preoperative planning is important because they may leave scars after surgery.
- Use of SkinPort: protects the wound by preventing friction between the skin and cannula
- Adoption of ultrafine cannulas: The smaller the diameter, the less invasive to the skin and the less visible the scar.
- Insertion opening location design: Select a location that is less noticeable, such as behind an underwear line or wrinkle.
Since these depend on the doctor's experience and aesthetic considerations, it is a good idea to check with the doctor in advance of the consultation to see what he or she is trying to do.
Postoperative Care] Specific examples of compression, moisturizing, and sun protection
The outcome after liposuction is determined not only by the procedure itself, but also by how the patient spends the time after the surgery. Especially during the first week or two immediately after the surgery, the tissue is at its most unstable, and proper pressure, moisturizing, and UV protection can greatly reduce the risk of problems such as scarring and pigmentation. Below are specific care details and precautions for each of these.
compression therapy
After liposuction, the skin and fat layers are temporarily loose. Firm compression of the affected area after surgery with a special garment helps prevent internal bleeding, swelling, skin sagging, and contracture, and helps the tissue recover in the correct shape.
In principle, "24-hour wear" is the rule for the first 1-2 weeks after surgery, after which it may be worn only at night, depending on the physician's judgment. In addition, too much tightness may cause blood circulation problems, so a moderate fit is ideal. It is important not to loosen or remove it at one's own discretion, but always seek guidance from a physician.
Moisturizing and wound care
The skin in and around the wound is very delicate and easily dried. Appropriate moisturization can support wound healing and help prevent inflammation, hyperpigmentation, and hypertrophic scars.
Vaseline, heparin analogs (prescription drugs), wound dressings, silicone sheets, etc. Always use items recommended by a physician rather than over-the-counter medications at your own discretion. These products promote regeneration by retaining moisture in the skin, reduce friction, and prevent the scar from worsening. Particular emphasis should be placed on areas that are prone to dryness.
sunblock
The skin after liposuction is prone to post-inflammatory hyperpigmentation. Exposure to ultraviolet light activates melanin, causing it to remain unevenly colored and darkened.
UV protection should be thoroughly applied for at least 6 months after surgery. Regardless of the season or weather, UV rays can affect the skin, and ideally should be combined with physical shielding such as long sleeves, parasols, and hats, in addition to the use of a high-performance sunscreen with SPF 50 or higher and PA+++ or higher. Consideration should be given to all areas to be treated, not just the face.
Preventing Deterioration] NG Behaviors and Limitations of Self-Care
Self-judgmental treatment after surgery may actually worsen scarring and hyperpigmentation.
- Massage before the wound is completely closed → cause bleeding and infection
- Self-use of over-the-counter whitening creams and peeling agents → chemical irritation worsens pigmentation
- Premature bathtub bathing and sauna → Excessive blood circulation worsens swelling and wounds
In cosmetic medicine, self-judgment that "this much is okay" is a risk. If you have any concerns, be sure to consult a physician and continue medically correct care.
What is medical care to improve liposuction scars? Major Treatments by Symptom
After undergoing liposuction, you may have made an effort and taken good care of yourself, but you still worry about the scars. Many people feel that there is nothing more that can be done at such times. However, there are medical options that can be arranged later.
Here, we will explain in detail how, to what extent, and by what methods the marks that have already appeared can be rectified, symptom by symptom. We hope that this will be of some hope to those who are suffering from the very same problem now. We will explain the possibilities of cosmetic medicine in a correct and gentle manner.
This for scarring? Effects and precautions of kenacort injections
If you are concerned about a raised scar that remains red for some time after surgery, it may be a condition called a "hypertrophic scar" or "keloid. Unlike common scars, this is a reaction in which an excess of fibrous components are produced deep within the skin, causing the skin to become hard and thick.
A medical approach to these scars is kenacol injection. Triamcinolone acetonide, a type of steroid, is injected directly into the scar in very small doses.
The injections are specialized for "bulging and hardened" conditions such as hypertrophic scars, and are characterized by a redness that diminishes over time and the bulge settles gently.
However, it is not a universal treatment that will always get better if injected. Particular attention should be paid to the risk of side effects.
- Recess," where the injection site is hollowed out
- Depigmentation," a whitening of the skin as if the pigment has been removed
- Atrophy, a thinning of the surrounding skin
Be sure to consult with a physician experienced in scar treatment, as these can vary in dosage, depth of injection, and timing. The doctor's skill is the key to safe and effective results.
Pigmentation Control! The Role of Lasers and Topical Medications
Many of these problems, such as "the scar itself has calmed down, but the dark spots have not disappeared," are known as post-inflammatory hyperpigmentation. Liposuction inevitably causes mild inflammation inside the skin, which may then lead to excessive melanin production.
The basic approach to improving this condition is to start with topical medications.
- Hydroquinone: a leading whitening ingredient that suppresses melanin production
- Tretinoin: Accelerates skin turnover (regeneration) and encourages pigment discharge.
- Azelaic acid: Relatively easy to use on sensitive skin and works slowly on hyperpigmentation.
These can be used with a doctor's prescription and are expected to slowly even out the skin color over a period of three to six months. But for pigment that still remains, there is the option of laser treatment.
- Q-switched ruby laser: Reaches deep into the melanin and specializes in brown to black pigment
- Pico-Laser (Picotoning): Gently treats shallow deposits and dullness with minimal skin irritation
The laser does not dramatically change the skin in a single session, but rather, it is imagined that transparency is gradually restored over a series of 2 to 6 irradiations. Picotoning in particular is easy to feel that the overall skin tone has been brightened, and the low risk is also attractive.
However, if redness is the main concern, IPL (light therapy) or V-beam may be more appropriate than picolaser. It is very important to determine the best way to treat your skin condition.
For bumps and redness! Potenza and regenerative treatment possibilities
After surgery, some patients suffer from an uneven appearance and wavy skin texture. In many cases, this is due to "contracture," which is adhesion or pulling between the skin and fascia as a result of the fat being suctioned out.
For this type of skin quality, it is difficult to improve with conventional drugs and surface treatments. This is where treatments based on regenerative medicine come in. Potenza is one such treatment that has recently been attracting attention. By using an ultra-fine needle to make countless microscopic holes in the skin and then irradiating radiofrequency (RF), heat is delivered to the deeper layers of the dermis to promote the rebuilding of collagen and elastin.
The appeal of this treatment lies in its ability to regulate the skin from deep within. It is not merely a superficial improvement, but a treatment that "leads the skin itself to a healthy and smooth state.
- Target symptoms: contractures, scars, craters, unevenness, redness, textural disturbances
- Approximate number of treatments: 3-5 times every other month
- Downtime: Redness and scabbing may occur for 2-7 days, but is relatively mild
In addition, Potenza can be effective on its own, but if a higher level of change is desired, it may be considered in combination with fractional laser or PRP (autologous platelet) injections.
Criteria for selecting a safe clinic
Cosmetic medicine, especially procedures such as liposuction, cannot be performed by everyone. If an inexperienced doctor performs the procedure, the risks of uneven suction, unevenness, excessive removal, sagging skin, and nerve damage increase dramatically. That is why it is most important to confirm how much experience and skill the doctor has in liposuction.
The wealth of experience is also directly related to the subtlety of the technique. The physician's ability to draw from a wide range of experience has a significant impact not only on the appearance of the results, but also on the downtime and postoperative comfort of the patient.
summary
In the majority of cases, the marks and scars that occur after liposuction become less noticeable with proper care and the passage of time. However, if symptoms persist or worsen, it is important to consult a medical professional rather than relying on one's own judgment.
Scars, pigmentation, and contractures have different treatments, and early intervention is key to recovery. The choice of clinic before undergoing the procedure also has a significant impact on the post-operative results.
Identifying physicians and facilities with expertise, reliability, and integrity, and having a system in place to receive ongoing aftercare, will lead to safe and satisfactory cosmetic treatment. Do not leave your body in a state of anxiety, but face your own body based on accurate knowledge and proper judgment.
