The key to skin renewal is a process where (1) the skin is irritated or slightly damaged by exfoliating agents or mildly damaged by other procedures ("sanding" by dermabrasion or burning by laser). This is followed by (2) a natural rebuilding of the skin that removes imperfections, rebuilds collagen and elastin fibers that tighten skin, and increases the amount of glycosamoinoglycans, the moisture-holding proteins that give skin its firmness. The stronger the exfoliation or skin damage, the stronger is the skin rebuilding action. Unfortunately, strong exfoliation causes strong skin irritation with itching, burning, and pain. And the results of laser resurfacing or dermabrasion depend on the skills of the practician. However, to get good results it is IMPERATIVE skin healing progresses at rapid pace.

Products which contain a low dose of glycolic acid combined with skin regenerating accelerators. When used as a long term skin care routine (2 to 4 months) it may be as good as a short term strong chemical peel or a skilled dermabrasion procedure. The skin regeneration accelerators are: allantoin and special proteins and peptides (amino-acid chains) that signal the body to start reproducing human skin cells.
