The Ordinary AHA 30% + BHA 2% Peeling Solution

• Beauty / Cosmetics

The Ordinary AHA 30% + BHA 2% Peeling Solution is a 10-minute exfoliating facial. With 30% Alpha Hydroxyl Acids (Glycolic/Lactic/Tartaric/Citric), 2% Beta Hydroxyl Acid (Salicylic Acid), Hyaluronic Acid Crosspolymer, Vitamin B5, Black Carrot and Tasmanian Pepperberry. Alpha hydroxyl acids (AHA) 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. 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, maximising 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.
