Product Return Policy

Unopened products may be returned for a full refund within 30 days of purchase.

Used products may be returned only in the rare event of allergic contact dermatitis. Please note that Retin-A (tretinoin) is irritating and may cause redness and peeling. Stinging and irritation may occur with the YS products, but these symptoms do not indicate allergy. We will be happy to evaluate any problems.
