The last phase of the physiological cycle of cell renewal is an excessive accumulation of dead cells (keratinocytes) on the surface of the epidermis. This layer of cells generates a thickening of the stratum corneum, giving the skin a decreased brightness, a color asymmetry associated with decreased hydration. The Exfolia line includes three products based on alpha-beta hydroxy acids studied for every type of skin imperfection, which include the best acids known in the cosmetic sector (Pyruvic Acid - Salicylic Acid - Glycolic Acid Mandelic Acid), and a cream based on Mandelic acid non-aggressive and specific for sensitive skin.
