Glycolic Acid is applied topically and as it is absorbed into the skin it works on separating the connection that holds dead skin cells together. Basically this formula helps to remove the upper layer of skin by detaching it from the layer underneath. This process boosts renewal of your skin and will leave it looking clean and bright and feeling soft and supple. Introducing a glycolic skin care to your routine will aid with exfoliation which will unclog pores and help any scarring to fade.
