Glycolic Acid for the Skin: Benefits and How to Use It

Properties of Glycolic Acid

Here are some of the properties of glycolic acid:

  • Exfoliating: As a chemical exfoliant, glycolic acid removes the outermost layer of skin cells and oil by dissolving them. Unlike mechanical exfoliants, such as brushes and face scrubs, glycolic acid does not require harsh scrubbing.
  • Antibacterial: According to a 2020 study, glycolic acid can inhibit the growth of certain bacteria.
  • Humectant [4]: Glycolic acid is also a humectant, which means it attracts and binds water to skin cells. It does this by increasing the synthesis of glycosaminoglycans, which are molecules that draw water in the skin.
  • Anti-aging: Glycolic acid can reduce some of the processes that cause visible signs of skin aging. For example it can increase collagen and hyaluronic acid in the skin and reduce sun damage. These substances give skin elasticity and structure.
