Citric Acid

Citric Acid

Citric Acid is an alpha-hydroxy acid (AHA) found in many fruits. It has a polar molecule and able to disrupt the coherence of corneocytes of the epidermis. This process called the chemical peeling type of exfoliation eliminating dull and old cells from the skin surface.

Studies found that CA enhances collagen I and procollagen II production improving skin firmness and elasticity. It increases the cell migration and renewal rate by inducing apoptosis through the mitochondrial pathway eliminating sun-damaged epidermal cells. Also, Citric Acid at high concentrations (20%) may improve the thickness of the epidermis and enhance amounts of GaGs in UV-damaged skin.
