Ingesting Collagen vs Topical Collagen: Which Works Better?

Collagen is a structural protein that supports the skin, bones, tendons, cartilage, and blood vessels. Because of its large molecular size, collagen cannot be absorbed directly into the bloodstream in its natural form.

If collagen were injected into the bloodstream in its native state, the body would not be able to properly process it. Instead, collagen must first be broken down into smaller amino acids so the body can absorb and utilize it.

When collagen is ingested, it is naturally broken down during digestion into amino acids and smaller peptides. These components are then used by the body as building blocks to support normal collagen production.

This is why many collagen supplements use hydrolyzed collagen (also called collagen peptides). Hydrolyzed collagen has been broken down into smaller particles, making it easier for the body to absorb.

Topical collagen products, on the other hand, are typically applied to the surface of the skin. While they may help with temporary hydration, the collagen molecules are usually too large to penetrate deeply into the skin.

Collagen fillers used in dermatology are different. These are injected directly into the skin by medical professionals to change the appearance of certain areas.

For everyday wellness routines, many people choose ingestible collagen powders as part of their daily nutrition.
