Acids for the face can be used in several ways, but always accompanied by a dermatologist’s indication. After all, only a specialized doctor can indicate which is the best acid for you.

But they are commonly used in physical peels, the most superficial type that promotes exfoliation and renews the skin. Thus, acids can be used in isolation or combined with chemical peels. These can be superficial, medium, and deep. This will depend on the recommendation and the purpose of the treatment. In this type of process, the most common acids are retinoic, salicylic, trichloroacetic, and glycolic.
