This is a guide to CO2 laser mole and seborrheic keratosis removal compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station Exit 1).
Many people are concerned about moles on highly visible areas such as the face, neck, or hands, and are looking into removing them. Moles can be covered with makeup, but with the trend of light makeup and its tendency to smudge easily in summer, it can feel more troublesome. However, there are various types of moles, and even the same type of mole can differ in depth and color from person to person, so it is necessary to first distinguish them rather than simply removing them.
Why do moles appear and increase?
Moles can be present from birth or develop later in life. Generally, the following factors are known to be involved:
- Repeated damage to the skin surface due to UV exposure
- Hormonal changes or skin aging
- Active melanin production due to a family history of many moles
UV rays are a common factor affecting not only moles but most pigmented blemishes. It is advisable to consistently use sun protection even after removal.
Not all moles are the same; their forms differ
Moles that are isolated are often not a major concern. On the other hand, multiple moles clustered together or distributed like a pattern can be more prominent on the face, arms, and neck, affecting one's impression. If they are small and light, they can be covered, but if they are large and dark, they can be an aesthetic concern.
Why diagnosis comes before removal
The care method differs depending on whether it's a mole, lentigo, or other pigmentation. Therefore, instead of applying the same program uniformly, it is necessary to assess the skin condition and create a personalized plan. At SHINE U Clinic Konkuk, we determine the approach after checking not only the moles to be removed but also other blemishes on the face.
What indiscriminate removal leaves behind
If too many moles are removed at once, the skin may not be able to withstand it, leading to damage. It is reported that if done incorrectly, it can lead to scars or other post-inflammatory hyperpigmentation. Therefore, it is crucial to choose a laser and intensity appropriate for the skin condition to minimize damage during removal.
If you want to find out what type of mole you have first
We look at depth, not just the surface
To achieve a clean result, it is necessary to consider not only the surface pigmentation but also the deeper pigmentation in the dermal layer. It is wise to make a decision after fully understanding how much care is possible.
Post-removal care is part of the package
The removal method and subsequent care differ depending on the type, size, and location of the mole, as well as your skin type. Receiving guidance on how to manage your skin after removal can help reduce irritation and maintain stable results.
While facial mole removal is considered relatively simple and has become common, incorrect care can actually cause irritation. Distinguishing the type and proceeding with a plan that considers depth is the first step towards clear skin.
The detailed care cycle and frequency vary depending on the condition of the mole, so please feel free to inquire if you have any questions.
