MUICIN - Aha 30% + Bha 2% Peeling Solution - Ultimate Exfoliation

This formula contains a studied Tasmanian Pepper-berry derivative to help reduce irritation associated with acid use. This derivative is of plant origin and varies in color seasonally and this color variation may be apparent in the formula from time to time. This formula is further supported with a cross polymer 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.  

Contraindications: This formula should not be used on sensitive, peeling or compromised skin. Please refer to additional sun protection note and other warnings in provided Directions.

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 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 favor 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.
