Many people visit the clinic with concerns that dark spots on their hands or face make their complexion look dull and make them appear older than their actual age. The first question is usually similar: "Can seborrheic keratosis be removed all at once with a laser?" To answer directly, seborrheic keratosis can be removed with a laser, but the method used and the recovery process vary depending on the size, depth, and location.

What are the skin changes of seborrheic keratosis?

Seborrheic keratosis is a pigmented skin change that appears as dark spots on areas frequently exposed to sunlight, such as the face or back of the hands. While pain or health threats are rare, as the number of spots increases, the overall skin tone can appear dark and dull.

As dull, spot-like marks increase, the complexion can look subdued and lead to an unhealthy appearance, so many people wish to clear up noticeable spots. Above all, it is important to first understand that seborrheic keratosis is a change significantly affected by UV radiation and aging.

What laser methods are available for seborrheic keratosis?

For seborrheic keratosis removal, there is a laser method that simply shaves off the lesion. This is similar to the principle used to remove noticeable moles. However, if the seborrheic keratosis is large or located in an area with a risk of pigmentation, it may be more helpful to remove it in one session rather than multiple sessions to reduce the possibility of pigmentation.

In such cases, using RePott Laser can be effective. RePott uses 1064nm and 532nm wavelengths to treat lesions located at different depths of the skin.

What pigments can RePott Laser be used for?

RePott uses two wavelengths together to broadly address pigment issues of different depths, such as melasma, freckles, and lentigo. It is characterized by its ability to treat pigments ranging from those close to the surface to relatively deep ones, by applying different wavelengths according to the pigment's location.

WavelengthPrimarily targets pigment depth
532nmPigment close to the surface
1064nmRelatively deep pigment

It is also a method that has recently gained attention from those who wish to see results quickly. However, since the type and distribution of pigment vary from person to person, it is necessary to determine the appropriate wavelength and intensity through consultation.

It is difficult to conclude that pigment changes like seborrheic keratosis will not reappear once treated. As it is an area affected by UV radiation and aging, post-treatment care is another crucial factor determining the outcome.

What to observe during the recovery period after treatment

Most cases show new skin gradually forming and scabs naturally falling off over a period of about 1 to 2 weeks. When estimating the next treatment cycle, it will be much easier to consider this recovery period as a reference. During recovery, it is good to take care of the following:

  • Do not forcibly remove scabs or peeling skin when they appear.
  • Wait patiently for the scabs to fall off naturally, even if it's a little uncomfortable.
  • Apply dressing or a band-aid to the affected area to maintain a stable condition.
  • Be careful to block direct UV exposure to the recovery area.
  • Moisturize sufficiently to keep the newly formed skin from drying out.

Simply observing the recovery process patiently can make a significant difference in the subsequent results.

If pigment remains after treatment

Even after laser treatment to clear dark spots on the face or back of the hands, pigment may remain faintly in some areas. In such cases, it is best to first identify the form in which the pigment remains and then consider appropriate aftercare.

If the remaining amount is very minimal compared to before treatment, you can manage it with vitamin C ampoules or melanin creams containing the whitening ingredient hydroquinone, while being careful to reduce UV exposure.

In the clinic, even what appears to be the same seborrheic keratosis often requires different aftercare directions depending on the form of the remaining pigment. Therefore, we recommend confirming your current condition before deciding on a course of action, rather than vaguely repeating the same care.

If the marks remain unchanged, you should re-examine them

If seborrheic keratosis marks remain similar to before treatment, a thorough check is needed to see if there are any other conditions or if the laser used was suitable for you. In such cases, we recommend visiting the hospital for another specialist diagnosis and consultation.

Among pigment changes that resemble seborrheic keratosis, there may be other underlying conditions. Since the approach varies depending on the type of pigment, such as Epidermal Pigment Removal for spots, seborrheic keratosis, and freckles, accurate differentiation is paramount.

How to think about recurrence and management

It is difficult to be certain that pigment disorders like seborrheic keratosis will never recur after one treatment. This is because these areas are significantly affected by UV radiation and aging. Therefore, middle-aged individuals who have been frequently exposed to sunlight often inquire during consultations whether the treatment has been successfully completed or if the condition is difficult to manage.

The key is to clear existing pigment while meticulously continuing post-treatment care. In addition to RePott Laser, there are various types of devices for treating pigment, so if a method suitable for you is chosen or combined, improvement can be expected. The first step is to determine a treatment routine that suits you through consultation.

If you are concerned about pigment on your hands, considering Lentigo & Nevus along with your overall skin tone can also be a good approach.
