Our skin cells regenerates on an average of 28 days, but lifestyle, health and age can slow down this natural cycle. The result: dull, flaky skin. To gently exfoliate your skin, try SOTHYS Face Scrub: a creamy emulsion that eliminates dead skin cells with rice powder, and moisturizes and calms irritation with white tea extract and shea oil. Perfect for sensitive skin. Retails at $82 for 50ml.
