Product Details Dermalogicas Circular Hydration Serum utilises an enhanced form of hyaluronic acid to penetrate skins surface for deep hydration and more supple radiant skin over time. An algae extract-infused moisturising matrix delivers quick and long-lasting hydration. Polyglutamic acid from fermented soy replenishes skins hydration reserves from within. Plant-derived sugars and a blend of amino acids similar to those naturally present in the skin trap water on skins surface to help prevent future hydration evaporation. A postbiotic blend of Lactobacillus Ferment and Avena Extract helps to balance skins microbiome. How To Use Smooth over cleansed face and neck morning and night after toning and before moisturising.
