The Ordinary Glycolic Acid 7% Toning Solution 240 ml

The Ordinary Glycolic Acid 7% Toning Solution 240 ml

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. The formula also improves the appearance of skin texture with continued use.

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

Contraindications: 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.

The 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 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 favour 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.

How to use:
Use ideally in the PM, no more frequently than once per day. After cleaning, saturate a cotton pad with the formula and sweep across the face and neck. Do not use it on sensitive, peeling or compromised skin. Avoid eye contour and contact with eyes. Do not rinse off. Continue with additional skin treatments as needed. Contact of the product with the skin must be of limited frequency or duration. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children.
