Brassica Campestris (Rapeseed) Sterols
What is Brassica Campestris (Rapeseed) Sterols?
Brassica Campestris (Rapeseed) Sterols consist of plant-derived lipids extracted from rapeseed oil, produced by the Brassica campestris plant, a common oilseed crop. Chemically, they are a blend of phytosterols such as campesterol, sitosterol, and brassicasterol, which structurally mimic human skin cholesterol. In skincare formulations, these sterols function as emollients and skin conditioning agents, typically appearing in moisturizers, creams, and balms. They integrate into the intercellular lipid layers of the stratum corneum, filling microscopic gaps to promote a smoother surface and bolster the skin barrier. This action supports hydration by minimizing transepidermal water loss without a heavy residue. Valued for their compatibility with skin's natural oils, rapeseed sterols offer a gentle, plant-based option for enhancing product texture and skin feel in daily routines.
