Science & Benefits

Fibroin is the insoluble protein that forms the structural core of silk. In cosmetic science, it is prized for its high percentage of glycine and alanine, which give it a unique affinity for human skin proteins. It functions as a dual-action humectant and absorbent; it can hold up to 50 times its weight in water while simultaneously absorbing excess surface sebum. This makes it an 'intellectual' choice for oily yet dehydrated skin, as it mattifies the complexion without stripping essential moisture. It is completely non-comedogenic and provides a luxurious, soft-focus finish that refines the appearance of pores.
