Quick Overview :Glycolic Acid 7% Exfoliating Toner (previously Glycolic Acid 7% Toning Solution) is an exfoliator that significantly smoothes skin texture and promotes the appearance of a more even skin tone, as well as more luminous skin, with regular use. It also reduces the appearance of lines and wrinkles. The water-based toner format is suited to daily use. It contains a 7% concentration of Glycolic acid - a well-studied alpha-hydroxy acid - and a plant-derived Tasmanian Pepperberry derivative, which varies in colour seasonally, and which may cause an apparent colour variation in the formula from time to time. This formula should not be used on sensitive, peeling or compromised skin. Please see the guidelines for extra sun protection information and warnings. The pH of this formula is about 3.6. Glycolic Acid has a pKa of 3.6, which is the most significant consideration when formulating with acids. The pKa value describes a molecule's acidity. When pKa is close to pH, there is an optimal balance of salt and acidity, which maximizes acid effectiveness while decreasing discomfort. The multi-functional solution can also be used on the scalp to help rebalance and relieve dryness by moisturizing the scalp skin. Made in Canada.
