Short answer: Vitamin C fuels the collagen production your skin relies on for firmness and radiance — the formula's most directly cited, research-backed mechanism.
Why collagen specifically connects to firmness
Collagen is a structural protein in skin tissue — supporting its production is a genuinely relevant, well-established pathway to a firmer-looking complexion.
What the cited research actually covers
Vitamin C's role in skin health is documented in Nutrients (Pullar et al., 2017) — a real, citable source, though this citation concerns the individual ingredient, not the finished DermaCept product.
💡 Worth knowing: these citations concern research on the individual ingredients, not the finished DermaCept product, which has not undergone independent clinical trials as a complete formula.
