The Ordinary Glycolic Acid 7% Toning Solution - 240ml

Glycolic Acid 7% Toning Solution is an exfoliant targeted at the surface of the skin. It helps improve skin clarity, balance uneven skin tone, and correct texture over time. This formula contains a Tasmanian Pepperberry derivative of plant origin which varies in colour seasonally and this colour variation may be apparent in the formula from time to time. 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.  This pH of this formula is approximately 3.6. Glycolic Acid 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.
