BIOCYTE CUCUMBER MASK is a face mask for people with oily, shiny skin who want a purifying, mattifying treatment. Excessive sebum production leads to oily skin, and certain factors, such as hormones, age, seasonal changes and climate, greatly influence its production. These factors can lead to oily, shiny skin and the gradual appearance of imperfections. CUCUMBER MASK is formulated with cucumber extract, tea tree oil and matmarine® on a bio-cellulose base, a 100% biocompatible nanofiber that acts like a second skin layer to deliver more active ingredients. A weekly application of CUCUMBER MASK helps regulate sebum production and unclog pores.
