A gentle exfoliant, in serum form. This mild solution helps improve skin clarity, balance uneven skin tone, and correct skin texture in a gentle yet effective way. How? Mandelic acid has a larger molecular weight than other alpha hydroxy acids, which results in a slower, more balanced distribution. Apply once daily, ideally in the evening. The formula can be diluted with other products to reduce strength until skin develops tolerance. Do not use on sensitive, peeling, or compromised skin. Avoid the eye contour and contact with eyes. Contact of the product with the skin must be of limited frequency or duration. If irritation occurs, rinse off, cease use, and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Refer to our website for a patch test guide, regimen guide, and product compatibility. Keep out of reach of children.
