Valuable CAS 153065-40-8 / SKIN CONDITIONING

It forms a protective yet non-greasy barrier on the skin, effectively minimizing moisture loss and optimizing overall hydration levels.

Emollient Skin-conditioning agent Antioxidant Moisture Barrier Support Hydration Optimizer Sebum Balancer

Science

Mechanism of Action

This oil functions primarily as an emollient, establishing a breathable, protective layer on the skin's surface that significantly reduces transepidermal water loss (TEWL) and maintains optimal hydration. Its distinctive composition, featuring over 98% long-chain fatty acids (eicosenoic, docosenoic, and docosadienoic acids), endows it with exceptional oxidative stability and resistance to rancidity. It also contains natural antioxidants, such as Vitamin E and phytosterols, which neutralize reactive oxygen species to mitigate photoaging indicators and combat free radical damage. Mimicking human sebum, Limnanthes Alba Seed Oil helps balance the skin’s natural oil production without leaving a greasy residue. Furthermore, it supports skin integrity by providing lipids essential for the cellular 'cement' between skin cells and may help inhibit collagen-degrading enzymes, offsetting some negative impacts of UVB exposure.
