Glycolic acid is one of the most effective anti-aging and renewing actives and Sesderma uses nanotechnology in its formulation so that you can get all its benefits with zero irritations. Using ACGLICOLIC 20 nourishing cream, you will see how your skin is reborn. Pores tighten, wrinkles shrink and dull skin is revived. It is ideal as a night cream and for dry and very dry skin. If we have never applied a cosmetic with glycolic acid, it is recommended to start with the ACGLICOLIC CLASSIC collection, which has a low concentration of this acid and, as our skin gets used to glycolic acid, we can apply a higher concentration (ACGLICOLIC 20) to maximize results and show a renewed and hydrated skin. You should only take the precaution of using sunscreen or use it only at night when you go to expose yourself to the sun, since its exfoliating effect increases the sensitivity of your skin to the sun. And in case you have mixed or oily skin, we recommend ACGLICOLIC 20 Gel Cream or ACGLICOLIC 20 Gel.
