What Is PERSEA GRATISSIMA (AVOCADO) STEROLS?
Persea Gratissima (Avocado) Sterols (牛油果甾醇) 是从牛油果油中分离纯化的植物甾醇复合物，主要含有 β-谷甾醇 (β-sitosterol)、菜油甾醇 (campesterol) 和豆甾醇 (stigmasterol)。植物甾醇与皮肤自身的胆固醇结构相似，可有效融入角质层脂质基质中，强化皮肤屏障，减少经皮水分流失 (TEWL) 并具有抗炎特性。
Key Skin Benefits
- + Barrier Reinforcement — 甾醇可直接补充角质层脂质
- + Anti-inflammatory — 减少炎症因子释放
- + TEWL Reduction — 临床证实可减少经皮水分流失
- + Skin Softening — 即时和长期的皮肤柔软效果
Pros
- + Structurally similar to skin's own cholesterol — excellent biocompatibility
- + Clinically proven to reduce TEWL and improve barrier function
- + Non-comedogenic — suitable for sensitive and acne-prone skin
- + Highly purified fraction — consistent efficacy versus whole oil
Cons
- − Premium-priced specialty ingredient
