C10-40 ISOALKYL ACID PHYTOSTEROL ESTERS.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, VISCOSITY CONTROLLING

A biomimetic lipid complex that replicates the natural cholesterol and sterol structures found in healthy skin barriers. This sophisticated emollient forms lamellar liquid crystal structures that seamlessly integrate with the stratum corneum to enhance moisture retention and barrier integrity.

Summary

emollient skin conditioning barrier repair viscosity controlling

Science

Mechanism of Action

Functions as a structural barrier enhancer by mimicking intercellular lipids in the stratum corneum, forming organized lamellar phases that reduce transepidermal water loss while stimulating endogenous hyaluronic acid synthesis and type III collagen production for comprehensive skin repair.
