Glycolic acid exfoliating toner 7% from The Ordinary, 100 ml

Glycolic acid product is an alpha hydroxy acid that exfoliates the skin. This 7% toning solution provides a gentle peel to improve the skin's radiance and visible clarity. The formula also works to improve the appearance of skin texture with continued use. This formula contains a carefully studied derivative of Tasmanian pepper berry to help reduce irritation associated with acid use. This derivative is plant-based and varies in color seasonally, and this color variation may be noticeable in the formula from time to time. The formula is also supported by the inclusion of ginseng roots and aloe vera for visible radiance and soothing benefits. Contraindications: This formula should not be used on sensitive, peeling, or damaged skin. Please refer to the additional sun protection note and other warnings in the provided instructions. The pH of this formula is about 3.6. Glycolic acid has a pKa of 3.6, and pKa is the most important aspect to consider in an acid formulation. KEA means acid availability. When the pKa is close to the pH level, there is an optimal balance between salt and acidity, increasing the acid's effectiveness and reducing irritation. Higher pH numbers in this case will increase the salt, making the formula more irritating than if the formula were more acidic. Olejimin Inganbin.
