The Ordinary AHA 30% + BHA 2% Peeling Solution

The AHA 30% + BHA 2% Peeling Solution is an at-home exfoliating facial that combines the power of alpha-hydroxy acids (AHA) and beta-hydroxy acids (BHA) to improve skin texture, reduce pore congestion, and address uneven skin tone. This high-strength peel is a recommended facial exfoliator for experienced users looking to achieve smoother, clearer skin. It features a Tasmanian pepperberry derivative, a known anti-irritant and further supported with hyaluronic acid, pro-vitamin B5 and black carrot.​

Note: Due to its high concentration of free acids, this solution should be used with caution, especially for those with sensitive skin. 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 optimal balance between salt and acidity.
