PUNICA GRANATUM STEROLS.

Valuable CAS - / HAIR CONDITIONING, SKIN CONDITIONING

Punica Granatum Sterols are potent plant-derived sterols, extracted from pomegranate seed oil, engineered to mimic the skin's natural cholesterol. Clinically shown to enhance skin hydration, restore density, and improve barrier function, they impart a remarkably smooth, velvety finish.

Science

Mechanism of Action

These plant-derived sterols are structurally analogous to the skin's inherent cholesterol, integral to the stratum corneum. By replenishing essential lipids, Punica Granatum Sterols fortify the epidermal barrier, significantly reducing trans-epidermal water loss (TEWL) and boosting hydration. Beyond their structural mimetic properties, they exhibit pronounced anti-inflammatory and antioxidant benefits, with potential UV-shielding attributes that help preserve collagen and hyaluronic acid synthesis, ultimately enhancing skin elasticity.
