← The FormularySkin & faceCollagen peptides
Also known as Hydrolysed collagen, bovine hide collagenReal but modest, and surrounded by a mechanism that is not true.
The story sold with this ingredient is that you swallow collagen and it arrives at your skin. That is not what happens — it is digested into amino acids like any protein. What the trials actually show is a modest effect on skin elasticity and hydration over a couple of months, which is worth having and is not a facelift. Anyone promising more is selling the mechanism rather than the result.
Collagen broken into short chains so it dissolves and absorbs. Made from bovine hide.
Not fully settled. The leading idea is that the peptide fragments act as a signal rather than as raw material, but the honest answer is that the effect is better evidenced than the explanation.
Supplies amino acids, notably glycine and proline, which the body uses when it makes its own collagen.
Anyone treating skin as a long game.
Daily, in anything. Unflavoured collagen disappears into coffee.
Nothing for two months. Then possibly a little.
Read the grams and ignore the marine-versus-bovine argument; type and dose matter more than source.
Read the labelBovine-derived, so not vegetarian or vegan. No meaningful safety concerns.
Evidence grades describe how well an ingredient is studied — A well-supported, C emerging — not a promise of results. Educational, not medical advice. Doses are typical ranges; follow the label on the product.
