GlossaryFractional Lasers

target small skin areas to boost collagen and rejuvenation

Fractional lasers, also known as fractional laser therapy or fractional laser resurfacing, are a type of laser treatment that targets small, precise areas of the skin to promote collagen production and skin rejuvenation. By creating microscopic columns of treated skin surrounded by untreated tissue, these lasers help in faster healing and are commonly used for reducing wrinkles, scars, and pigmentation issues.
