Science
Mechanism of Action
As a phytosteryl ester, Phytosteryl Nonanoate integrates into the skin's lipid matrix. It is known to form lamellar liquid crystals, structurally similar to the skin's natural lipid bilayer. This action reinforces the skin barrier, improves water retention in the stratum corneum, and ultimately leads to enhanced hydration and a smoother skin texture.

Safety
Safety Profile
The CIR Expert Panel found Phytosteryl Nonanoate, as part of the phytosterol and steryl alkanoate group, to be safe. Tests indicated little to no irritation or sensitization from dermal and ocular exposure. Related phytosteryl glutamate esters have been safely used at concentrations up to 25.6% in leave-on products, while general phytosterols are used up to 5% in specific applications like lipsticks and 3% in general leave-on products. No evidence of maternal, teratogenic, genotoxic, or carcinogenic effects was found for the group.
