The molecular weight of mandelic acid is 152.1 daltons which is larger than other alpha hydroxy acids (glycolic acid is 76.0 daltons, for example). 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. 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.
Contraindications: This formula should not be used on sensitive, peeling, or compromised skin. Please refer to additional sun protection note and other warnings in provided Directions.
Note: While exfoliating acids can result in quick visible benefits, we generally suggest the use of indirect forms of skin exfoliation in favour of direct forms such as this formula due to potential inflammation and sensitivity associated with acids. Please refer to NIOD’s Non-Acid Acid Precursor for such a suggested formula.
How To Apply:
Apply once per day, ideally in the PM. Can be diluted with other treatments to reduce strength until skin develops tolerance. Do not use on sensitive, peeling or compromised skin. Avoid contact with eyes. Contact of the product with the skin must be of limited frequency or duration. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children. Sunburn Alert: This product contains an alpha hydroxy acid (AHA) that may increase your skin’s sensitivity to the sun and particularly the possibility of sunburn.

Patch tests are an easy way to help predict if you may experience a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating any new product into your regimen. We have outlined a general method for conducting your own patch test below based on the type of product.
Apply a small amount of the product onto a clean area of skin on the upper forearm.
Keep the area dry.
If the product has a specified duration of use, rinse off after this time has elapsed. Otherwise rinse off after 24 hours.
If any redness, burning, itching, blistering or irritation is observed at any time throughout the test, do not use the product.
