Kick-start skin’s hydration cycle: long-lasting serum immediately floods skin with hydration, replenishes from within, and helps prevent future hydration evaporation. Full-circle hydrating serum utilizes an enhanced form of Hyaluronic Acid to penetrate skin’s surface for deep hydration and more supple, radiant skin over time. An Algae Extract-infused moisturizing matrix delivers quick and long-lasting hydration. Polyglutamic Acid from fermented Soy replenishes skin’s hydration reserves from within. Plant-derived sugars and a blend of amino acids similar to those naturally present in the skin trap water on skin’s surface to help prevent future hydration evaporation. A postbiotic blend of Lactobacillus Ferment and Avena Extract helps to balance skin’s microbiome.

Overall good product
"This serum has a lightweight texture that absorbs quickly without leaving a sticky feeling. It provides good hydration and leaves my skin feeling soft and refreshed. Overall, it’s a nice product, though I would need more time to see noticeable long-term results."

Winning Post-Menopausal Dryness Battles
"As a 52-year-old going through post-menopause, my skin completely changed almost overnight. My once-reliable combination skin became incredibly dry and dull due to all the hormonal shifts. Standard moisturizers just weren't cutting it anymore, so I decided to try this serum—and I am so glad I did! It gives my skin an immediate, beautiful glow and a deep surge of hydration that actually lasts all day. It sinks right in without feeling heavy or greasy, plumping up my skin and making it feel soft and comfortable again. If your skin has become dry and depleted from hormonal changes, you need this in your routine. It has completely restored my skin's radiance!"
— Angela S. (5/5)
