Glycolic Acid possible treatment for scar tissue??? I'm looking into possible treatments for scarred tissue. One substance I have come across is Glycolic Acid. It is used extensively in cosmetic creams and skin peels in a <10% concentration and is used for deep tissue skin peels by dermatologists in >10% concentration. The essential activity incurred is the breaking down of the binding lipids which in turn releases dead skin cells from the surface layers of the epidermis. As it is to my understanding, the same activity can occur deeper inside the tissue also allowing for restructuring of the skin in the process reducing wrinkles and creating softer skin. Could this be an effective means of reworking scarred tissue???
