Facial serum with retinol by Dermalogica, suitable for all skin types. Retinol, also known as vitamin A, significantly contributes to the function of cell renewal, provides firmness, and helps in skin regeneration. It is recommended that the initial applications be at more spaced intervals, for example, 1 to 2 times a week. Thanks to its composition, the serum is quickly absorbed and penetrates deeper into the skin compared to facial creams, providing anti-aging protection.
