This “soft” version of a peel uses a solution that never exceeds a glycolic acid content of 19 per cent. This treatment is carried out with no medical training at a beauty institute. It is a superficial treatment that requires many sessions and produces subtle results.

This type of peel works at a deeper level and is considered to be a “moderate” or “deep” treatment compared to the previous type due to its glycolic acid concentration, which ranges from 20 per cent to 70 per cent. This type of treatment, used most often by those over the age of 40, is ideal for addressing issues such as aging skin manifested in the form of brown spots, skin irregularities, loss of elasticity and radiance, as well as for younger people who have dilated pores, acne scars, or skin that is compromised due to overexposure to the sun. This treatment requires medical supervision, pre- and post- peel treatments, and is offered at epiderma. Note that AHA medical peels are gentle compared with TCA peels (see description a little farther on).

As an example, for the best results the AHA medical peel generally requires eight sessions every two weeks for the initial treatment, followed by scheduled maintenance sessions every three months. The number and duration of intervals between treatments depends on the individual.

The protocol is as follows:
• Initial consultation with a physician who examines the skin, sets progressive treatment parameters, and gives the client relevant information about the strict care routine that must be followed for two weeks following treatment.
• Sessions: The liquid solution is applied to the face by a qualified technician.
• The solution is left on the skin to penetrate for three to five minutes, under constant supervision.
• The skin reacts: tingling is felt and temporary redness appears.
• The solution is then properly neutralized by applying several washcloths soaked in cold water.
• The client must carefully follow the skin care protocol after each treatment.
