Kick-start skin's hydration cycle with Dermalogica's Circular Hydration Serum. This long-lasting serum immediately floods skin with hydration, replenishes from within, and helps prevent future hydration evaporation. Circular Hydration 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. Lactic Acid, an Alpha Hydroxy Acid (AHA), helps to brighten and smooth skin. 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.
