01 How can I recognise dehydrated skin? Dehydrated skin doesn’t necessarily mean dry skin! Whether your skin is dry, normal, combination or oily, its water needs must be met. When it's thirsty, it shows as the skin tissue is weakened and cannot retain the water it contains.This situation is not permanent but temporary. It passes as soon as the skin is sufficiently hydrated. Clarins Research pushes the limits of hydration with the creation of the Hyaluronic Power Complex. A double dose of hyaluronic acid for an immediate and long-term hydration boost. Combined with an exlusive leaf of life extract which is full of rich moisturising benefits, Clarins products containing this Hyaluronic Power Complex can be applied generously.
