Chemical peels have been time-tested. Alpha-hydroxy peels are highly popular in the dermatologist’s arsenal of procedures. Glycolic acid peel is the most common alpha-hydroxy acid peel, also known as fruit peel. It is simple, inexpensive, and has no downtime. Depth of the glycolic acid peel depends on the concentration of the acid used, the number of coats applied, and the time for which it is applied. Hence, it can be used as a very superficial peel, or even a medium depth peel. It has been found to be very safe with  skin .

GA has the smallest molecular weight amongst all the alpha-hydroxy acids. It penetrates skin easily .They are available in various concentrations ranging from 20%–70%. The higher the concentration and lower the pH, the more intense the peeling will be .        Glycolic peels classified as: very superficial (30%–50% GA, applied for 1–2 minutes); superficial (50%–70% GA, applied for 2–5 minutes); and medium depth (70% GA, applied for 3–15 minutes). GA peels have antiinflammatory, keratolytic, and antioxidant effects. 

Application methods
 After the skin has been cleansed and degreased, GA solution is applied using cotton buds or a brush in a sequential manner starting from the forehead to the left cheek, chin, right cheek to cover the entire face. Care is taken to protect the eyes and the corners of the nose and lips. The peel is neutralized within 3–5 minutes, or when uniform erythema is seen. If frosting is observed in any particular area before the set time or end-point, it is important to neutralize the peel immediately. It is always better to start with a low concentration (20% GA) and increase the concentration and application time during subsequent sessions. Peeling is repeated once every 15 days for 4–6 months until the desired result is achieved.

Alpha-hydroxy acid peels can be neutralized with water or with basic solutions, such as ammonium salts, sodium bicarbonate, or sodium hydroxide.

 

 

With whatever peel you start with, patch test first! For a patch test:
Apply a small amount of product on your skin in a discreet area, like the inside of your wrist or your inner arm.
Wait 48 hours to see if there’s a reaction.
Check the area at 96 hours after application to see if you have a delayed reaction.
Incorporate it slowly into your routine. Your patience will be rewarded, and safety is of utmost importance. More isn’t necessarily better here!
