Light therapy provides additional benefits after the HydraFacial™ treatment. LED light therapy uses specific types of light, which give off energy that stimulates your cells, thereby increasing your skin’s production of collagen and elastin. In turn, your skin becomes firmer, less wrinkled and younger looking. The treatment’s red LED light helps improve the appearance of skin firmness and resilience, while reducing the appearance of fine lines and wrinkles, hyperpigmentation and other signs of aging. The blue LED light is extremely beneficial for people who suffer from oily skin or breakouts. And the combination of red and blue LED lights is helpful in reducing the appearance of rosacea.
