Collagen & skin: what science does (and doesn’t) say

Marketing loves “collagen = perfect skin”. The regulatory framework is clear: no health claim is approved for collagen on skin function (negative opinions under art. 13.5).

We communicate via nutrients with real EFSA claims: zinc and biotin contribute to the maintenance of normal skin; vitamin C contributes to normal collagen formation by the body.

A nuance, but an honest one. That’s Protokol.
