Sederma say Evermat is an efficient treatment for oily skin, based on a plant extract containing protoberberines, associated with an active extracted from olive tree leaves. This association controls the sebum flux acting on the number of sebocytes but also on the level of 5-a reductase.
After 28 days of treatment on a group of 22 panellists, Evermat is claimed to have exhibited a reduction of the sebum flow by 29%, and the number of active glands by 49%.
An evaluation of pore size and skin shine shows a drastic reduction of these parameters according to Sederma:
• Skin shine has been reduced up to 55%
• Pore size has been reduced up to 36%
Oily skin results in a shiny appearance of the skin and dilated pores. People with oily skin tend to exfoliate their skin in the erroneous belief that they will thus reduce the shine. In fact they actually excite the sebaceous glands, which in reaction produces excess sebum over the following hours. It is estimated that 10% of women suffer from oily skin on a regular basis.
