Punica Granatum Sterols are plant-derived sterol mixtures extracted from pomegranate seed oil, structurally similar to skin’s natural cholesterol. These compounds deeply support the epidermal barrier by replenishing essential lipids, reducing trans-epidermal water loss (TEWL), and enhancing skin hydration. When incorporated into formulations at 0.5 – 5%, they deliver pronounced moisturizing benefits, restore skin density, and offer a velvety, satin finish — making them ideal for high-performance moisturizers and barrier-repair products.
While research is less abundant in hair applications, Punica Granatum Sterols function effectively as conditioning agents. In shampoo and conditioner systems, they improve smoothness, shine, combability, and reduce frizz — offering a botanical alternative to lanolin or petrolatum, perfect for sensory-focused and sustainable hair care lines.

Safety Analysis
Safety Confirmation by CIR
The Cosmetic Ingredient Review includes pomegranate sterols within the phytosterol family, deeming them safe as used in current concentrations and product formats. Phytosterols serve multiple beneficial functions including skin and hair conditioning, viscosity enhancement, and antioxidant activity.
Hydration and Barrier Performance Data
Independent studies (e.g., Active Concepts) have demonstrated that at 5% usage, pomegranate sterols significantly improve skin hydration (~24% increase over baseline) and reduce TEWL. Their water-holding capacity notably exceeds that of avocado sterols, jojoba oil, and even petrolatum. In haircare trials, 2% inclusion in shampoos and conditioners yielded measurable improvements in smoothing, combability, hydration, shine, and frizz control.
Sustainability & Sensory Advantages
These sterols are biodegradable (≈88%), free from petrochemicals and animal products, and can serve as natural replacements for lanolin or petrolatum — meeting modern sustainability and clean formulation demands.
