Solution for evening out skin color with 7% glycolic acid

Skin tone evening solution with glycolic acid 7% is an exfoliant targeting the surface of the skin. It helps increase skin clarity, unify uneven skin tone, and improve texture over time. This formulation contains a derivative of Tasmanean pepper plant, which varies in color from season to season, and this color variation may appear in the formulation from time to time. This formulation should not be used on sensitive, peeling, or at-risk skin. Please refer to the additional sun protection note and other warnings in the attached instructions. The pH of this formulation is about 3.6. Glycolic acid has a pKa of 3.6, and pKa is the most important aspect to consider when formulating acids. pKa means acid availability. When pKa approaches the acidity level, there is an optimal balance between salt and acidity, which increases the effectiveness of the acid and reduces discomfort.
