The Ordinary Glycolic Acid 7% Toning Solution is an exfoliating toning solution that targets the surface of the skin. It helps improve skin clarity, balance uneven skin tone, and correct texture over time. The formula contains a 7% concentration of glycolic acid, which is a well-studied alpha-hydroxy acid. Glycolic acid is known as the most effective form of AHA that provides the most benefits for the skin. It exfoliates the skin gently by removing dead skin cells, which leaves the skin feeling fresher, newer, and smoother. It also improves the collagen production in the skin to leave skin firmer and younger.
The toning solution also contains a Tasmanian Pepperberry derivative of plant origin, which varies in color seasonally and this color variation may be apparent in the formula from time to time. Other ingredients include amino acids, aloe vera, ginseng, and glutamic acid. Glutamic acid is a humectant moisturizer and skin-conditioning agent that also seems to affect skin barrier repair.
The toning solution is water-based, alcohol-free, oil-free, and silicone-free. The pH of the formula is approximately 3.6, which is close to the pKa of glycolic acid. This balance between salt and acidity maximizes the effectiveness of the acid and reduces irritation.
It is important to note that this formula should not be used on sensitive, peeling, or compromised skin. It is recommended to use no more frequently than once daily, ideally in the evening, after cleansing and before anhydrous serums, oils, suspensions, or creams. It is also important to use sunscreen during the day when using this product.
