“Laser light is designed to pass through the skin until it reaches its target, where it’s absorbed by the targeted cell and converted into heat. The cell is damaged by the heat, then heals itself. “When the cell heals, we can see clinical improvement,” says Harbor-UCLA Medical Center Director of Dermatologic Surgery, Lisa Chipps, M.D. “The beam of light you see is a laser wavelength targeted to treat a specific component and depth of the skin, a scientific principal known as selective photothermolysis,” explains Dr. Chipps.”
