The Claim

Daily oral intake of 8000 mg of hydrolysed marine collagen supplemented with 60 mg vitamin C for 12 weeks reduces dermal collagen fragmentation by 44.6% compared to placebo in adults aged 40–60 years with visible signs of aging.

In plain English

A daily supplement containing 8000 mg of hydrolyzed marine collagen and 60 mg of vitamin C, taken for 12 weeks, decreases collagen breakdown in the skin by 44.6% in adults aged 40–60 with visible aging.

See the scientific wording

Daily oral intake of 8000 mg of hydrolysed marine collagen supplemented with 60 mg vitamin C for 12 weeks reduces dermal collagen fragmentation by 44.6% compared to placebo in adults aged 40–60 years with visible signs of aging, as measured by confocal microscopy.

Why this might work

When you take the collagen supplement, your digestive system breaks it down into tiny pieces called peptides. These peptides travel through your blood to your skin, where they tell your skin cells to make more collagen. Vitamin C helps these skin cells build strong, stable collagen fibers and also protects existing collagen from damage by neutralizing harmful molecules. Together, these actions reduce collagen fragmentation and improve skin structure.
