Enzymes are proteins that act as biological catalysts, i.e., they affect the rate of a chemical reaction. They are represented in numerous skin care preparations. They contribute to the removal of dead cells by helping to break down keratin from the surface layer of the skin. This procedure accelerates the process of skin regeneration. After treatment, the skin is smooth, gentle, and radiant. They significantly affect the reduction of skin depigmentation, giving a fresh and even complexion. A great advantage of using enzymes is that they are completely safe for all skin types, even the most sensitive ones. They give results in a short period of time, without signs of any irritation. They are mostly of neutral pH value, so they do not disturb the pH value of the surface layer of the skin.
