Step Peel is a specific and progressive peel concept. It is recommended that you use European Pharmacopoeia quality trichloroacetic acid in a solution with ultra pure distilled water in a mass and mass concentration in a glass bottle opaque to light. The bottle must have a stopper with dropper tube in order not to contaminate the solution with a cotton stick swab. Store preferably in the refrigerator.
Recommended concentrations: 18% - 21% - 24% - 27% - 30%.

= research for the optimum concentration from week to week.

Aqueous solutions of trichloroacetic acid are very acid. The pH of an aqueous solution with a 0.1 molar rate is 1.2. In aesthetic dermatology, the practitioner generally prefers to use solutions with a concentration of 35% and sometimes even higher. The pH of these solutions becomes formidable.

This is why it is important to test the cutaneous reaction with solutions of increasing concentration.

A reminder of indications: the clinical aspect of skin treated with a solution of trichloroacetic acid depends on the concentration used and on the strength and time of application.

1st stage: redness
2nd stage: frosting
3rd stage: bleaching
4th stage: hardening
5th stage: withering

In the Step Peel concept, the operator will try not to go past the frosting or perhaps bleaching stage.

The practice of chemical peeling shows that the weekly repetition of a peel at low concentration produces a number of impressive long-term aesthetic effects, while assuring the patient comfort, safety and a continuation of social activity.

By using various concentrations of trichloroacetic acid, the Step Peel concept is the best way of finding out the patient’s sensitivity, tolerance and limit of acceptance of a particular peel. Once these parameters are known, the rule must be “For each patient, his optimum concentration”.

= the different areas of the face do not react in the same way to the same concentration of trichloroacetic acid. Thanks to the variety of concentrations the practitioner will be able to establish a true mapping of the cutaneous reaction of the face and neck according to the concentration of trichloroacetic acid used. Once this mapping is determined, the rule will be “For each zone, its maximum concentration”. This research for the minimum effective concentration is the 1st reason for the decrease in side effects of TCA.

The 2nd phase of the Step Peel concept is the cream mask. This should be applied as soon as the frosting or bleaching stage has been reached.

Target: Protect the skin with 17 components judiciously chosen for total efficacy.

Moisturizing, soothing, firming up, lightening, healing, anti-age and antioxidant action. (Muscat rose oil, Ac Kojic, Salix Alba, Methylsilanol Manuronnate, Boswellia Serreta extract, Vitamin K, Ribes Nigrum, Karite butter, Allantoïn, Wheat germ oil, Carotene, etc.)

The cream mask is the 2nd reason for the decrease in side effects of TCA.
