Dr. C. Tuna Resurface Hydrasooth Essence 100ml is a deeply hydrating and calming facial essence that bridges the gap between toner and serum, delivering a concentrated infusion of moisture-binding and skin-soothing actives to prepare the complexion for the resurfacing treatments that follow. Hyaluronic acid at multiple molecular weights penetrates various layers of the skin to provide both surface-level and deep hydration, plumping up dehydration lines and creating a supple, bouncy texture that looks healthy and feels comfortable. Soothing botanical extracts including centella asiatica and allantoin calm any sensitivity or redness that may arise from the resurfacing actives used in other steps of the regimen, ensuring that the skin remains balanced and comfortable throughout the renewal process. The watery, fast-absorbing texture layers beautifully without pilling or heaviness, making it an ideal hydration-boosting step that enhances the efficacy of every product applied afterward. This generous 100ml bottle provides months of daily hydrating and soothing support within the comprehensive Resurface skincare system.
