The Ordinary Glycolic Acid 7% Exfoliating Toner, 100ml at John Lewis & Partners

Glycolic Acid is an alpha hydroxy acid that exfoliates the skin. This 7% toning solution offers mild exfoliation for improved skin radiance and visible clarity, while also improving the appearance of skin texture with continued use.

This formula contains a studied Tasmanian Pepperberry derivative to provide comforting benefits to the skin. It is further supported with the inclusion of ginseng root and aloe vera for both visible radiance and soothing benefits.

The pH of this formula is approximately 3.6 and Glycolic Acid has a pKa of 3.6. The pKa is the most important aspect to consider when formulating with acids as it implies acid availability. When pKa is close to pH, there is an ideal balance between salt and acidity, maximising the effectiveness of the acid and reducing the potential of developing irritation. Higher pH values in such a case would increase the concentration of salt, which counter-intuitively would make the formula even more irritating than if the formula was more acidic.

Good to know: This formula should not be used on sensitive, peeling or compromised skin. Please refer to additional sun protection notes and other warnings in provided Directions. While exfoliating acids can result in quick visible benefits, we generally suggest indirect forms of skin exfoliation for a gentler approach.
