Combinations of α-hydroxy acids in different concentrations and with different pH, which act as a superficial chemical peel.  Formulated for the treatment of photo-damaged skin with irregular pigmentation, skin with blemishes, imperfections such as post-acne scars, dilated pores, opaque appearance due to hyperkeratosis, and also for oily, seborrhoeic and acneic skin.  They can be recommended for the treatment of problematic, adolescent and blemished skin. Thanks to their exfoliating and lightening properties, they help to improve the appearance of the skin surface, giving it a fresher and smoother look. In addition, alpha-hydroxy acids promote the synthesis of mucopolysaccharides, collagen and elastin, essential components of the dermis, helping to improve hydration and firmness. Thanks to the combination of α-hydroxy acids with retinyl palmitate, which stimulates metabolism and renewal, the skin appears much finer, silkier and velvety.
