The Claim

Daily oral supplementation with 5 g hydrolyzed collagen and 80 mg vitamin C for 16 weeks reduces periorbital wrinkle volume by 13.8%, maximum wrinkle depth by 16.9%, and indentation index by 8.5% in women aged 40–65, as measured by 3D multispectral analysis.

In plain English

Taking 5 grams of hydrolyzed collagen and 80 mg of vitamin C every day for 16 weeks reduces crow's feet wrinkles in women aged 40 to 65. The treatment decreases wrinkle volume by 13.8%, depth by 16.9%, and a measure of skin roughness by 8.5%.

Daily supplementation with 5g hydrolyzed collagen and 80mg vitamin C for 16 weeks reduces periorbital wrinkle volume by 13.8%, maximum depth by 16.9%, and indentation index by 8.5% in women aged 40-65, as measured by 3D multispectral analysis.

Why this might work

When you digest the collagen supplement, it breaks into tiny protein pieces that enter your blood and travel to the skin. There, they tell skin cells to build more supportive fibers like collagen and keep them from breaking down. Vitamin C helps this building process. Over time, the skin becomes thicker and firmer, making wrinkles less deep and less visible.

  1. Study: The Effects of Dietary Supplementation with Collagen and Vitamin C and Their Combination with Hyaluronic Acid on Skin Density, Texture and Other Parameters: A Randomised, Double-Blind, Placebo-Controlled Trial

    The study tested the exact same supplement (collagen plus vitamin C) in the same age group for the same amount of time, and found that wrinkles got smaller and less deep, just like the claim says.
