Collagen + Biotin

Has hydrolyzed collagen like the source but completely lacks biotin and vitamin C, so two of three actives are missing.

Contains hydrolyzed collagen but no biotin or vitamin C, and is built around snail mucin, a totally different active focus.

Only shares biotin; no vitamin C (calcium ascorbate) or hydrolyzed collagen, the two other hero actives, are present at all.

Has trace hydrolyzed collagen but no biotin or vitamin C, and it's a foot mask formula with unrelated actives like urea and snail secretion.

Uses different vitamin C derivatives (ethyl ascorbic acid, tetrahexyldecyl ascorbate) instead of calcium ascorbate, and has no biotin or collagen.
