The Clarins Hydraquench Intensive Serum is an intensive, moisture-replenishing bi-phase and hydrating facial serum that revives ultra-thirsty skin. Acting at all levels of the skin it helps to restore the skin's natural appearance hydration mechanisms and maintain moisture levels for newly replenished skin. With targeted moisture for dehydrated skin, the active ingredients – Katafray, Sorbier bud and Chondrus crispus extracts – work to reinforce the surface skin’s barrier effect and boost skin hydration and radiance. The lightweight moisturiser is as invisible as it is comfortable for the skin. This intensive facial hydrating serum leaves dehydrated skin soft, comfortable, and radiant, with a matte finish produced by an effective formula.
