A 12-week daily regimen of hydrolysed collagen plus vitamin C reduces facial wrinkle depth by 19.7% compared to placebo in adults aged 40-60 with crow's feet, as assessed by profilometry Rz index.

When you take the hydrolysed collagen and vitamin C supplement, your digestive system breaks the collagen down into tiny protein pieces called peptides. These peptides travel through your blood to your skin, where they tell your skin cells to make more collagen. Vitamin C from the supplement helps your body build strong collagen by acting as a helper in the chemical process, and it also protects your existing collagen from damage caused by sun exposure and stress. Over 12 weeks, this process increases the amount and quality of collagen in your skin, making wrinkles less deep.
