This rigorous 16-week, double-blind, placebo-controlled clinical trial focused on the effects of daily supplementation with 5 grams of hydrolysed collagen (HC) and 80 mg of vitamin C, with or without 30 mg of hyaluronic acid (HA), in women experiencing signs of skin aging.
The results were significant: after just 8 weeks, there was a 16% improvement in dermal density, with improvements continuing through the full 16 weeks. Skin roughness was reduced by up to 9.9%, and wrinkle volume decreased by nearly 14%. These outcomes demonstrate how collagen supplementation can positively influence skin health, with scientifically backed evidence.
The findings of this clinical trial mirror those from previous studies using higher doses of collagen, suggesting that even a lower daily dose, when taken over an extended period, can yield remarkable skin benefits. This adds further weight to the growing body of clinical evidence supporting collagen’s role in skin regeneration.
Furthermore, the study’s extended intervention period emphasized the importance of long-term supplementation, showcasing that consistent collagen intake can bring about substantial structural changes in the dermis — the deep layer of the skin responsible for elasticity and firmness.
This clinical research reaffirms collagen’s effectiveness as a key ingredient in skincare, contributing to an ever-expanding body of scientific data.
