Ingredient
Collagen in a cream
Also called: Topical collagen
Too large to rebuild your collagen. It mostly sits on the surface and washes off.

What Sharon would tell you
Collagen in a cream is not the same as collagen in your skin. The molecule is too large to penetrate deeply and rebuild the dermis.
If you want your skin to make more collagen, think retinoids, vitamin C, peptides, and appropriate procedures. Topical collagen may moisturize temporarily, but it is not a collagen strategy.
