Glycolic acid derived from sugar cane is by far the most commonly used substance by dermatologists for peeling applications. This alpha-hydroxy acid removes dead skin cells that hinder the skin's respiration and slow down the physiological renewal of skin cells. To ensure maximum effectiveness, compatibility, and safety of use, the researchers at Collistar have focused on achieving optimal balance in the pH level and concentration of glycolic acid, and have added two other alpha-hydroxy acids – mandelic and gluconic acid – to round out and modulate the effects. Designed for daily use, the product provides an effective, gradual, and non-aggressive peeling that regenerates the skin day by day, helping it to regain its natural perfection. Pure active formulas without water, preservatives, fragrances, alcohol, or dyes.
