The Ordinary Glycolic Acid 7% Toning Solution
DESCRIPTION & BENEFITS
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 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 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. 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.
Use ideally in the PM, no more frequently than once per day.
After cleaning, saturate a cotton pad with the formula and sweep across face and neck.
Do not use on: sensitive, peeling or compromised skin. Avoid the 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.
