Hydra-Lock Lotion
With Ceramides
Healthy skin starts with a strong skin barrier. Made with ceramides, squalane, panthenol (vitamin B5), and skin-identical lipids, this lightweight lotion supports the skin's natural moisture barrier.
Key benefits include long-lasting hydration, a reduced appearance of redness, more comfortable feeling skin in cold and dry conditions, and support of the skin barrier with skin-identical lipids.
Made with care and loved by our customers, this signature bestseller is said to be deeply hydrating without feeling heavy or greasy. Users often report that their skin still feels moisturized the next day after application.
