Glycolic acid is part of the family of alpha hydroxyl acids. They are a family of naturally acids such as lactic acid (milk acid), malic acid (from apples), tartaric acid (wine), citric acid (citrus).


Glycolic acid is derived from sugar cane, which has a molecular weight lower than the other (2 carbons), and better penetration.

Glycolic acid at high concentrations (50-70%) is used exclusively for medical use to treat specific diseases of the skin.

It has a dual action:

* The first is to smooth, moisturize and give brightness to the skin through a peeling of the surface layer of the skin (stratum corneum), facilitating and stimulating cell renewal and thus combating the effects of aging. Indeed, the epidermal cells (keratinocytes) for action of glycolic acid, multiply thus promoting a significant increase in the spinous layer of young cells did.
* The second is to activate the physiological mechanisms by which increases synthesis of collagen, obtaining an improvement in overall skin tropism.

The Glycolic Acid, promoting superficial peeling, contributes to eliminate the pigmented cells, also allows better penetration of hydroquinone, a substance that blocks the formation of melanin.

It also works as a powerful exfoliant which also evens out the top and bottom area of a scar. Scars have reportedly become flatter and less visible with the use of a glycolic acid product for 6 months to a year.

There are 50% and 70% solutions as well, performed only by professionals.

Personally, I have experienced once-a-week peelings with glycolic acid 30% at home could be very helpful in reduction of facial scars and creating a smooth skin.

I recommend you to start using low strengths of Glycolic Acid because your skin needs to get used to it first. You don’t want to damage your skin, so always start with low strengths first.
