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 to help reduce irritation associated with acid use.  The formula is further supported with inclusion of ginseng root and aloe  for both visible radiance and soothing benefits.  

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.  implies acid availability. When  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.
