Photo therapy, is an application of light in specific wavelengths, red and blue. This type of therapy has been proven effective in treating Acne, Psoriasis, Eczema, wound healing, and aging. There is also no down time when using light therapy devices.
When treating acne, blue light therapy waves are absorbed into the skin and the P.acne bacteria absorbs the rays causing them to self-destruct. Once the acne causing bacteria is removed, inflammation and pustules clear up.
Red photo light therapy penetrates deeper into the skin and stimulates collagen to create new, healthier cells. In addition, red light therapy also slows down inflammation, what some dermatologists think causes wrinkling of the skin.
