PHYTOSTERYL OLEATE.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING

A bioactive ester of phytosterols and oleic acid, Phytosteryl Oleate precisely mimics cholesterol to fortify the skin's barrier function. It enhances hydration, reduces moisture loss, and contributes to improved skin texture and elasticity, targeting signs of aging.

Science

Mechanism of Action

Phytosteryl Oleate operates as a multifaceted lipid, leveraging its composition of barrier-supporting phytosterols and emollient oleic acid. Phytosterols integrate into the stratum corneum, structurally mimicking cholesterol to reinforce the skin's natural barrier, thereby minimizing transepidermal water loss and offering anti-inflammatory benefits. Oleic acid provides complementary moisturizing and skin-smoothing effects. This synergistic action promotes sustained hydration, refines skin texture, and encourages collagen synthesis, ultimately enhancing elasticity and contributing to a reduction in the visible signs of aging.
