Can I use Skinoren 2 times a day to use Dermogal A+E during the day?

Care should be taken when combining cosmetics with exfoliating acids - here: Skinoren (azelaic acid) with retinol - here: Dermogal A + E. All exfoliating acids can be introduced only when the skin is already accustomed to retinol, it does not show any signs of irritation, dryness or redness. If vitamin A has been used for a long time and the skin responds well to it, you can gradually introduce acids tailored to your skin type. In this case, I would advise against Dermogal A + E. Capsules contain evening primrose seed oil, the so-called fatty emollient. It can be comedogenic, i.e. promote the formation of blackheads. It is better to replace it with Sensilix duo concentrate of the Pharmaceris brand: https://www.gdziepolek.pl/app/produkty/88923/pharmaceris-a-ae-sensilix-duo-koncentrat-z-wit-ae-w-27-skwalanie-plyn/apteki Please also pay attention to the proper hydration of the skin of the face and the use of preparations with a restorative effect on the lipid coat of the skin, preferably with a UV filter.
