The Ordinary AHA 30% + BHA 2% Peeling Solution: A 10 minute exfoliating facial masque containing AHA, alpha hydroxyl acids, and BHA, beta hydroxyl acids, to resurface dull, tired looking skin revealing a more youthful complexion.

AHA 30% + BHA 2% Peeling Solution contains 30% Alpha Hydroxyl Acids; Glycolic/Lactic/Tartaric/Citric; and 2% Beta Hydroxyl Acid, Salicylic Acid, to remove surface skin cells and to unclog pores.

Alpha hydroxyl acids (AHA) help to exfoliate the skin's topmost surface for a brighter and more even appearance. Beta hydroxyl acids (BHA) also exfoliate the skin with an extended function to help clear pore congestion. This combined 32% AHA/BHA solution offers deeper exfoliation to help fight visible blemishes and for improved skin radiance. The formula also improves the appearance of skin texture and reduces the look of fine lines with continued use.

This formula contains a studied Tasmanian Pepperberry derivative to help reduce irritation associated with acid use. This derivative is of plant origin and varies in colour seasonally and this colour variation may be apparent in the formula from time to time. This formula is further supported with a crosspolymer form of hyaluronic acid for comfort, Vitamin B5 to assist healing and black carrot as an antioxidant.

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

This 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 effectiveness of the acid and reducing irritation. Higher pH numbers in such a case would increase salt which counter-intuitively would make the formula even more irritating than if the formula was more acidic.

Note: While exfoliating acids can result in quick visible benefits, we generally suggest indirect forms of skin exfoliation in favour of direct forms such as this formula due to potential inflammation and sensitivity associated with acids. Please refer to NIOD's Non-Acid Acid Precursor for such a reference.
