Understanding Melanin and Its Role in Skin Health
Melanin is the natural pigment responsible for the color of your skin, eyes, and hair. Produced by melanocytes—specialized cells located in the skin—it plays a critical role in shielding your body from ultraviolet (UV) radiation. While many aesthetic concerns stem from changes in melanin levels, melanin itself is essential for protecting your skin and preserving its integrity.
Rather than being a problem, melanin is a key player in maintaining healthy, youthful-looking skin. When properly balanced, it gives your skin tone richness and uniformity. However, when disrupted, it can contribute to concerns such as discoloration. For conditions like hyperpigmentation and melasma, we invite you to explore our dedicated pages.

Laser-Melanin Interactions
Laser absorption by melanin is an important component of medical and cosmetic treatments that use lasers. Alex 755 nm, Diod laser 810, and ND:Yag 1064 are three wavelengths often used to reduce the appearance of dark spots on skin resulting from hyperpigmentation. Alex 755 nm has been used for years to target brown patches, birthmarks, and tattoos. Diod laser 810 is better suited for targeting hair follicles, and ND:Yag 1064 can reach deeper layers of skin without disrupting surrounding healthy tissue. This is the most frequent laser for Laser hair removal and skin rejuvenation.
