Backed by Nature & Research
The only formula of its kind — combining 15% L-Ascorbic Acid, upcycled Coffee Silverskin Extract, and a 4-chain Hyaluronic Acid Complex — is available exclusively at Tepi Naturals. Our ingredients are sustainably sourced and gently formulated to preserve their powerful bioactive compounds.
15% L-Ascorbic Acid is the most bioactive and clinically studied form of Vitamin C. Published research shows that 10–15% topical L-ascorbic acid significantly improves skin brightness, reduces dark spots, increases collagen production, and decreases signs of photoaging over 12 weeks.
Upcycled Coffee Silverskin Extract is rich in antioxidant polyphenols (including chlorogenic acids) and naturally occurring caffeine that help defend skin against oxidative stress and support a smoother, more resilient complexion.
The 4-Chain Hyaluronic Acid Complex delivers multi-molecular-weight hydration that reaches different layers of the skin for superior plumping and barrier support.
