Glycolic acid derived from sugar cane is by far the substance most commonly used 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, Collistar's researchers 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 effect. Developed for daily use, the product provides an effective, gradual, and non-aggressive peeling that regenerates the skin day by day and helps it regain its natural perfection. Pure active formulas without water, preservatives, fragrances, alcohol, and dyes.
