Go deeper and get results. Target the root cause of dehydration with a reenergising algae-activated complex of vitamins, minerals and antioxidants, clinically proven to increase deep skin hydration for up to 72 hours.

Powered by a moisture-maximising matrix infused with Wild Rosella and sustainably sourced Algae Extracts, this water-jelly osmo-hydration serum floods skin with moisture —then draws it into the skin like a magnet — to intensively revitalise and deliver relief from dehydration deep down† when, and where, you need it most. Wild Rosella, rich in organic osmolytes, targets the root cause of dehydration and rejuvenates tired skin. Freshwater Algae and Hyaluronic acid work in synergy to replenish the skin’s hydration reserves. Green Caviar Algae visibly smooths skin with plumping hydration. REN's Hydra-Smart Technology helps to disperse hydration evenly throughout the skin.
