LED light therapy energizes the skin cells similar to how the sun effects plants through photosynthesis. It is a completely natural process. Low intensity light waves, with the right parameters, penetrate deep into the skin to increase fibroblast activity and increase collagen and elastin synthesis.
The blue LED light specifically penetrates the skin, and the bacteria that causes acne absorbs the light and releases oxygen, which kills the bacteria.
LED light therapy treatments are a great add on to other services, such as facials, chemical peels, microdermabrasion, and laser treatments.
