Like a stint in a spa when your skin's showing signs of fatigue, 111SKIN's Y Theorem Bio Cellulose Facial Mask works to quickly replenish, recharge and awaken dulled, lacklustre skin types.

Infused with a cocktail of strengthening complexes, inspired by wound-healing processes, these bio-cellulose masks have a 'second skin' benefit. Not only do they assist the penetration of the stimulating they are filled with regenerative ingredients too. With fibres 500x finer than tissue masks, bio-cellulose helps to 'lock in' hydration, delivering powerful actives to where they're most needed. With sea anemone peptides (a biomimetic peptide that calms inflammation and soothes irritation) alongside ectoin and centella Asiatic which shield against aggressors, the star is the N-Acetyl Cysteine. As a skin conditioning component, it wards against aggressors and performs a vital role in the creation of collagen and elastin.

Apply the middle Bio-Cellulose layer to clean, dry skin. Wear for 20 minutes. N.B. Use up to three times per week, and for longer durations when extra hydration is needed.

Formulated by globally renowned Harley Street cosmetic surgeon, Dr. Yannis Alexandrides, 111SKIN has quickly become the go-to for skin-savvy celebrities (we're talking everyone from Priyanka Chopra to Margot Robbie), beauty editors and skin care obsessives alike. And with the iconic Y Theorem Bio Cellulose Facial Mask Box, we can see why.
