Infused with the exclusive Idro-Attiva® Complex, as well as peony and Néré fruit extracts, this mask helps the skin maintain its glow and vitality for up to 72 hours. To maximize the flash effect of this product, use it for 10 minutes at a time whenever the skin is particularly dull and dehydrated. After just one application, the complexion will visibly destress, emerging revitalized and more radiant than ever.
