With AHA and Hyaluronic Acid
The Ordinary Mandelic Acid 10% offers superficial dermal peeling that is gentler than other alpha hydroxy acids.
This larger size allows mandelic acid to penetrate the skin more slowly which in turn makes it very gentle and suitable for all skin types including the most sensitive skin.
You don't need a concentration of more than 10%, because then you would simply be achieving an indirect peeling strength that is more easily offered through lower percentages of glycolic acid.
