- Vitamin C (L-ascorbic acid) provides antioxidant protection, brightening, and some collagen stimulation. However, its effectiveness for wrinkle treatment specifically lags behind both retinoids and copper peptides in comparative studies.
- The same study showing 70% collagen increase for copper peptides found only 50% for vitamin C, a notable difference. Vitamin C's primary strength lies in antioxidant protection and pigmentation treatment rather than structural wrinkle improvement.
- The two ingredients shouldn't be used simultaneously due to potential destabilization, but they complement each other when used at different times. Morning vitamin C (antioxidant protection during sun exposure) with evening copper peptide (collagen building during sleep) represents a logical combination strategy.
