Collagen and Vitamin C Skin Claims: What the Wording Means
By Glow Nutrition1 min read
Who this is for: UK buyers trying to understand collagen products that use vitamin C skin wording
Vitamin C is the claim route, not collagen
Many collagen products include vitamin C because it has authorised wording connected to normal collagen formation for the normal function of skin.
That does not mean the collagen ingredient gets an authorised skin claim.
For the broader version, read Vitamin C and Collagen Formation.
The clean label wording
The safest structure is: contains vitamin C, which contributes to normal collagen formation for the normal function of skin, when conditions are met.
The risky structure is: collagen supports skin because vitamin C is present.
Claims note
This article is regulatory guidance. It does not claim collagen improves skin. Nutrient claims must stay attached to the authorised nutrient and meet conditions of use.
