The Ordinary AHA 30% + BHA 2% Peeling Solution 30ml

AHA 30% + BHA 2% Peeling Solution exfoliates multiple layers of the skin for a brighter, more even appearance. With the help of alpha-hydroxy acids (AHA), beta-hydroxy acids (BHA), and a studied Tasmanian pepperberry derivative, which reduces irritation that can be associated with acid use, this at-home peel helps even skin texture, clear pore congestion, and improve uneven pigmentation. The formula is further supported with a crosspolymer form of hyaluronic acid for comfort, pro-vitamin B5 for hydration, and black carrot for added protection.

Note: This formula contains an extremely high concentration of free acids. We recommend use only if you are an experienced user of acid exfoliation and your skin is not sensitive.

The pH of this formula is approximately 3.6. Glycolic Acid, the primary AHA used in the formula, has a pKa of 3.6 and pKa is the most important aspect to consider in formulating with acids. pKa implies acid availability. When pKa is close to pH, there is an ideal balance between salt and acidity, maximizing the effectiveness of the acid and reducing skin discomfort.
