Saturated with the anti-ageing power of 5 days’ worth of serum, our Anew Essential Youth Maximising Sheet Mask provides your skin with an instant boost. Working to repair your skin’s cells for a firmer, more youthful look, over time it also helps to reduce fine lines and wrinkles. How to use me: It’s so easy to use. Simply place the mask over your face and leave for 10-15 minutes. Once you’ve removed the mask, be sure to massage your face until all of the serum has been absorbed.
