Laser hair removal works by directing light into pigmented hair follicles. That light is absorbed by melanin and converted into heat, destroying the follicle while sparing surrounding tissue. It’s why people with fair skin and dark hair often experience the best outcomes.
Why Dark Skin Needed New Laser Options
But dark skin contains more melanin overall, making earlier lasers vulnerable to misfiring: instead of heating only the follicle, the laser could heat the skin cells too. That has led to risks like burns, hyperpigmentation, hypopigmentation, and scarring, effectively excluding darker-skinned patients from safe treatment for decades.
