What is Biodroga Expert Acids Glycolic Acid Peel 20%?
Biodroga Medical Institute Expert Acids Glycolic Acid Peel 20% is a single-strength professional exfoliating treatment. It comes from the Expert Acids line, part of Biodroga’s Medical Institute. Glycolic acid is the smallest of the common alpha-hydroxy acids. As a result, it can penetrate the skin’s surface evenly.
This bottle contains the 20% concentration, the entry strength in Biodroga’s 20/35/50% Expert Acids Glycolic Acid range. It is intended for use in a licensed treatment room.
Key benefits of Biodroga Expert Acids Glycolic Acid Peel 20%
- Refines rough texture: formulated to exfoliate the skin’s surface for a smoother feel following a series of treatments.
- Supports an even tone: formulated so that regular sessions help fade the look of past pigmentation and brighten the complexion.
- Softens the look of fine lines: formulated to support the appearance of firmer, more resilient-looking skin over a course of treatments.
- Mix-and-match protocol: estheticians can combine this 20% strength in equal parts with other Biodroga Expert Acids for a customized treatment. Options include, for example, salicylic or mandelic acid.
Key ingredients
Biodroga’s own product description names glycolic acid, at 20% concentration in this bottle, as the sole active driving the peel. This AHA comes from sources such as sugar cane and unripe grapes. It also has a reputation as the classic, gold-standard AHA for professional exfoliating treatments.
According to the brand, estheticians can tailor it to different skin concerns. This depends on concentration as well as on how they combine it with other acids.
However, Biodroga has not published a full INCI list for this Expert Acids peel. For that reason, this section reflects only the active the brand names in its own materials.
How to use
- Mix up to three Expert Acids in equal parts (6 ml total) if combining acids, or use this peel alone.
- Apply the mixture evenly to the cleansed face; add an extra 6 ml if also treating the neck and décolleté.
- Leave on for the time appropriate to the client’s skin and the chosen protocol, then rinse thoroughly with water.
- Apply Biodroga’s Acid Peel Neutralizer for about 30 seconds, then remove.
- Finish with the client’s regular skincare routine, including daily SPF.
For professional use by licensed estheticians only. Always patch-test new clients before a full application. Also advise strict daily sun protection before, during and after a course of glycolic acid treatments.
