Vitamin C Serum (L-Ascorbic Acid, Ferulic Acid and Vitamin E) Clinical Study
Share
The powerful trio of 15% Vitamin C (L-Ascorbic Acid), 1% Vitamin E, and 0.5% Ferulic Acid has been extensively studied for its impact on skin health. In a peer-reviewed clinical study published in the Journal of Investigative Dermatology (2005), participants using a formulation identical to this blend experienced:
-
✅ Up to 36% reduction in fine lines and wrinkles
-
✅ 40% improvement in skin tone and pigmentation clarity
-
✅ 15–20% boost in skin firmness and elasticity
-
✅ 8x increase in photoprotection, enhancing sunscreen effectiveness
These results were seen after daily use over 12 weeks. The antioxidant synergy of these ingredients not only corrects visible skin damage but also prevents future oxidative stress, making it a gold-standard combo in anti-aging skincare.
