Garnier introduces a new generation of face masks that are enriched with lemon and Vitamin C. Use the Garnier Sheet Mask if you have dull and dehydrated skin with spots. The Garnier Light Complete Serum Mask instantly hydrates and brightens skin, revealing a younger-looking and fairer complexion. 1 sheet mask gives you 1 week worth of serum and the serum sheet mask is suited for all skin types. How to use: Unfold the Garnier face mask sheet. Apply on clean face with blue protective film facing outwards. Remove the blue film. Adjust the sheet mask to the contours of your face. Leave it on for 15mins. Remove the sheet mask and gently massage your face with the excess serum.
