RePott Laser DuoDERM for Lentigo Removal: No Worries About Efficacy or Side Effects? | Yonsei Star Dermatology Sinchon

Dark lentigo or seborrheic keratosis on the face, once formed, rarely lighten, becoming a constant concern when looking in the mirror. Even after deciding on laser treatment, the most common question we hear is, "Can I tolerate the DuoDERM regeneration patch applied afterward, more than the procedure itself?"

In the previous article, we explained the principle by which RePott Laser treats pigmentary disorders like lentigo, and the process of treatment and management at the clinic. This time, we will focus on the recovery period, specifically the DuoDERM stage, which patients are most curious about after treatment.

Many individuals meticulously combine laser treatment with home care, such as whitening creams and ointments, to erase lentigo or seborrheic keratosis. Nevertheless, it's not uncommon to feel frustrated when the pigment spreads rapidly, darkens further, or the number of lesions doesn't seem to decrease.

A common difficulty in treating pigment with lasers is that it's not easy to complete in a short period. Since improvement often occurs gradually over multiple consistent sessions, there can be times when patients wonder, "Is it really fading well?"

RePott Laser is known as a device with a strong advantage in treating lesions in a relatively short period without repeated procedures. Its biggest feature is its ability to address dull pigment with fewer sessions. However, the treatment process involves one important step: managing the treated area with a regeneration patch like DuoDERM for about 2 weeks.

Because the procedure involves irradiating the skin with strong light, the skin immediately after treatment is weaker than usual. This 2-week period is approximately how long it takes to protect the treated area from external stimuli, reduce the risk of infection, and aid in regeneration and recovery.

We always emphasize to patients that how they spend this period can make a difference in the results. However, some patients feel burdened by the idea of wearing DuoDERM for two weeks before the procedure.

Patients with allergic reactions to regeneration patches often worry, "Will I not be able to receive treatment?" or "Will I see less effect than others?" In such cases, it is most important to thoroughly explain your skin condition during the pre-procedure consultation.

Here are some important points to check and confirm during the consultation stage:

• Have you ever experienced an allergic reaction to DuoDERM or medical tape?
• Do you have a history of skin conditions such as contact dermatitis?
• Is your skin usually sensitive or prone to redness?
• Are you taking any medications or undergoing other skin treatments?

If you have contact dermatitis, not just a simple allergy, you may experience discomfort during the DuoDERM stage after RePott Laser. When the skin comes into contact with external foreign substances, it can be more irritated than others, quickly becoming red, itchy, or painful. This is a common complaint among those with sensitive skin.

Since the skin is weakened immediately after laser treatment, it may be better to aid rapid recovery with a regeneration patch. However, if discomfort persists, such as continuous pain or worsening redness in the treated area, even before the 2 weeks are up, it is safer to contact the clinic promptly and visit to receive appropriate measures and additional care.

In the examination room, we often observe that patients who communicate even small changes during the recovery period tend to have a more comfortable 2-week experience overall.

When skin is wounded, regeneration patches like DuoDERM are commonly used to protect the affected area. While widely used as a management item that helps speed up recovery and reduce side effects like secondary infections, it is important to use it appropriately depending on the individual and situation. Since lentigo and seborrheic keratosis are known to be difficult to treat, it's good to remember that recovery management is as crucial a variable as the procedure itself in determining the outcome.
