The Biocyte unitary neckline mask is a bio-cellulose mask that acts like a second skin and ensures optimal penetration of the active ingredients. It contains hyaluronic acid, Formosa RubyTM and wasabi which help reduce dark spots, hydrate and plump the skin. The skin is subjected to various external aggressions (pollution, bacteria, the sun ...) and internal (poor diet, tobacco consumption ...) generating inconveniences such as skin imperfections, and the formation of brown spots. This mask contains sacran, a polysaccharide derived from algae that reduces the depth of wrinkles (-26% of wrinkles in 4 weeks) 1. Wasabi extract helps reduce dark spots by reducing melanin formation (-40%) 2 and tyrosinase activity (-24%) 2. Formosa RubyTM reduces the formation of free radicals through its anti-oxidant effect (-80%) 3. Thus the skin is free of dark spots and signs of aging. It is advisable to separate the sheets delicately. Remove the 1st braided paper. Place the mask on your décolleté, on clean, dry skin. Remove the 2nd braided paper. Press lightly and leave to act for 15 to 20 minutes. Remove the mask and allow the rest of the serum to penetrate by massaging. Keep out of the reach of children. External application. Do not ingest.
