Brown spots that gradually increase on the face in the mirror are a change everyone faces with age. When pigments like lentigo or seborrheic keratosis settle in, there are limits to covering them with makeup, so many people consider laser treatment. Among these, RePott Laser is often mentioned, but you might feel vague about how much pain it involves or what to be careful about during the recovery period.
Therefore, this time, we have compiled the story of a director who personally received pigment treatment in a Q&A format. From the reason for choosing the procedure to immediate skin changes after treatment, and the essential care to follow during recovery, we will address the questions patients are most curious about, one by one.
Why do lentigo and blemishes increase with age?
As we age, various signs of aging appear on the skin. Representative examples are wrinkles and pigmentation. Even without much sun exposure, you may notice an increase in facial blemishes over time.
Epidermal Pigment Removal (blemishes, seborrheic keratosis, freckles) are bothersome in daily life, but understanding their principles and setting a treatment direction can reduce vague worries. Since the approach to pigment disorders varies by type, accurately identifying your skin condition is the first step.
Q. Among various pigment lasers, why did you choose RePott Laser?
The reasons can be largely summarized into two. First, it can minimize damage to the surrounding skin. It allows for relatively precise laser irradiation, reducing damage to surrounding skin tissue while enabling selective pigment treatment. With less concern about damage to the surrounding skin, the burden of the procedure can also be reduced.
Second, it can approach even faint pigments. Generally, the fainter the pigment, the more difficult the treatment, and the greater the color difference, the better the effect. In the case of RePott, treatment effects can be expected even for faint blemishes, and it can also be applied to thick blemishes, making it reported as a relatively satisfying laser.
In the examination room, even if they look like the same blemishes, their depth and concentration vary from person to person, so it is important to confirm what kind of pigment it is before treatment. If you have hesitated to treat faint blemishes, it may be helpful to examine the scope of epidermal pigment removal procedures together.
Q. Was there any pain or discomfort during the treatment?
A major advantage is that the pain is relatively low. If necessary, anesthetic cream can be used to further reduce the pain. Even without separate anesthesia, it feels like a slight sting, similar to the intensity felt when a rubber band is lightly flicked.
The reason for the low pain is thanks to the powerful cooling device built into the machine. Cooling the skin reduces pain, and RePott Laser has a cooling device installed at the front to reduce the pain felt during the procedure.
The degree of pain can vary from person to person, so if you are usually sensitive to pain, it is advisable to discuss anesthesia methods in advance before the procedure.

Q. How does the skin condition change immediately after treatment?
Immediately after the procedure, the color of the brown spots turns white. This is because the laser uses strong energy to separate the epidermis and dermis layers.
Air fills this area, making it appear white, and over time, it turns into a brown scab. After the procedure, a patch like DuoDerm is applied. Initially, there will be a slight discharge, and the area will swell. After about 2-3 days, it will gradually subside, becoming slightly darker overall.
RePott Laser also performs cooling after the procedure to constrict blood vessels in the treated area and reduce side effects. Therefore, there is usually no significant discomfort that would be concerning for the skin condition. Some people worry that the effect might be minimal or that marks might make daily life difficult, but while there may be individual differences, it is reported that daily life can be continued.
During recovery, manage it this way
Since RePott Laser uses strong energy, wound care after the procedure is paramount. The essential points to follow during the recovery process are as follows:
- Apply a hydrocolloid bandage (DuoDerm) for about 2 weeks to ensure proper wound healing.
- If the patch falls off before the period, immediately disinfect and reapply the same hydrocolloid bandage.
- Failure to adhere to the application period may lead to inflammation or secondary pigmentation, so caution is needed.
- Gently cleanse with a mild cleanser to minimize irritation to the weakened skin.
- After the procedure, consistently use sunscreen to prevent pigmentation.
Since wound care leads to the result, when considering laser treatment for epidermal pigment removal like blemishes, seborrheic keratosis, or freckles, it is advisable to plan for daily life management during the recovery period as well.
Q. I'm worried about recurrence after treatment. How can I prevent it?
Generally, it is not common for pigment to reappear in the treated area. However, some people may experience pigmentation easily with age, over time, or depending on their skin type.
Therefore, it is good to pay attention to post-care. Even if the blemish cells in the skin have been removed, a temporary slight pigmentation may be visible in the treated area. To prevent this, consistent sun protection is important.
If you wash your face vigorously when your skin is weakened after laser treatment, it can cause significant irritation. Gently cleansing with a mild cleanser can help reduce the risk of recurrence, lessen worries about pigmentation, and maintain the effect for a long time.
Things to check before the procedure
The key points from the RePott Laser Q&A are summarized at a glance as follows:
| Question | Director's Key Point |
|---|---|
| Pain | About the intensity of a light rubber band flick, even without separate anesthesia, alleviated by a cooling device |
| Immediately after treatment | Brown spots turn white, then gradually become brown scabs |
| Recovery care | Apply DuoDerm for about 2 weeks, swelling subsides after 2-3 days |
| Recurrence prevention | Consistent sun protection and gentle cleansing |
RePott Laser is a laser used for pigment disorders such as lentigo and seborrheic keratosis, but even for the same blemishes, the appropriate treatment varies depending on their depth and concentration. Accurately checking your pigment condition before the procedure and planning for recovery period care and sun protection increases the likelihood of satisfactory results.
If you are confused about the procedure name or scope of application, please refer to the RePott Laser pigment treatment guide, and we recommend confirming the degree of pain and recovery period through a consultation, as there may be individual differences.
