• Low-oxidation technique maintains freshness & efficacy
• Ultra-fine filtration for a clean, silky finish
• Naturally rich in antioxidants without additives

Glossary of Scientific Terms 📘

• Phytosterols: Plant compounds that strengthen the barrier
• Tocopherols: Vitamin E molecules that protect lipids
• EFAs: Essential fatty acids required for barrier health

Dermatologist Insight 🧑⚕️

“Cucumber Seed Extract is one of the best lightweight lipid sources for people whose skin feels tight, dry, or compromised. Its linoleic acid content makes it ideal for barrier repair without heaviness.”

Consumer Perception Results ⭐
