This lightweight night serum utilizes the skin-renewing power of retinol to re-build, smooth and repair the skin's surface. Retinol is a derivative of vitamin A and is highly regarded for its youthful properties. Encapsulation helps target skin cells where it would provide most benefit and enhances skin penetration. With a high strength of 2%, this transformative ingredient helps increase the rate of skin turnover, as it amplifies collagen production and protects against free radicals for younger-looking, more radiant skin. Not suitable for those who are pregnant. Dermstore has partnered with Flex to allow you to use your Health Savings Account (HSA) or Flexible Spending Account (FSA).
