Dr. Jane Yoo, a board-certified dermatologist, explains laser safety for people with darker skin tones. Melanin-rich skin faces higher risks of burns, scarring, and permanent pigmentation changes. She covers which laser wavelengths work best, why conservative settings matter, and what aftercare prevents complications.
Hi, I'm Dr. Jane Yoo, a board-certified dermatologist and Mohs surgeon based in New York City. As a Korean American physician, I know how important it is to approach laser treatments thoughtfully, especially in the AAPI population. During Asian American and Pacific Islander Heritage Month, I want to address an issue that's often overlooked: laser safety in skin of color. AAPI skin has a higher baseline melanin content and and more active pigment cells. This makes it more reactive to heat-based devices like lasers and light treatments. When not used properly, these devices can cause complications such as post-inflammatory hyperpigmentation, hypopigmentation, burns, and even scarring. The risk of the complications is often tied to how the device is selected and used. Lasers that use shorter wavelengths or higher energy can unintentionally target melanin in the skin. Not just in the intended lesion. Aggressive settings, overlapping passes, and lack of adequate cooling can also contribute to unwanted side effects. Intense pulsed light, for example, should be used with caution, and fully ablative resurfacing procedures like CO2 lasers require special consideration, especially in darker skin types. That doesn't mean lasers are unsafe. In fact, when used correctly, lasers can treat many common conditions in AAPI patients, including acne scars, pigmentation, and unwanted hair. So understanding the differences between ablative and non-ablative devices is important. Ablative lasers, like traditional CO2, remove layers of skin and carry higher risk. Non-ablative lasers, like the 1064 Nd:YAG, target deeper structures without removing the skin surface and often preferred for hair removal and vascular concerns. Fractional non-ablative lasers, like Fraxel, can be a good option for resurfacing and acne scars, offering controlled results with reduced downtime. Pico-second lasers, which rely on extremely short pulse durations and photomechanical effects, have also shown good safety profiles in treating pigment conditions with minimal disruption to surrounding tissue. What matters most is that the provider understands how these technologies interact with melanin-rich skin. This includes choosing the right laser, using conservative energy settings, performing test spots, and providing appropriate aftercare like strict sun protection and gentle skincare. Some patients in the AAPI community may hesitate to pursue laser treatments because of concerns about safety or past experiences. However, with the right expertise, laser laser treatments can be both safe and effective.
