We carry out dermatologist-testing for all of our products. However, not all products are tested in the same way. For most of our products, an RIPT (Repeated Insult Patch Test) is performed. Our Hydration Sensitive line, a sensitive-RIPT was performed with subjects with self-claimed sensitive skin. Only the latter group of products indicate "dermatologist-tested" so customers with sensitive skin can rest assured these formulas are appropriate for their skin.   If your skin is sensitive to specific ingredients, we recommend that you review the ingredients list on our website, or on our packaging, with your dermatologist or physician.
