Do collagen supplements actually reach the skin?

Randomised trials of hydrolysed collagen peptides consistently show measurable skin elasticity and hydration changes at 8-12 weeks. The mechanism is signalling, not direct deposit.

Which one should I start with?

If you're building a routine from scratch, start with collagen, it has the broader outcome data. Add hyaluronic acid if dryness is the primary complaint.

Are marine collagen and bovine collagen equivalent?

Both work. Marine peptides tend to be smaller and are typically absorbed slightly faster; bovine has more legacy trial data.

Norwegian Marine Collagen vs Hyaluronic Acid

Skin support from the inside. Both appear in skin-health formulas. They work on different layers of the same story: structure versus hydration.

The short answer

Marine collagen supplies peptide fragments the body reassembles into structural proteins in the dermis, the trial evidence points to skin elasticity and hydration. Hyaluronic acid holds water at the tissue level and shows up in trials as improved skin moisture and reduced dryness. They complement each other; most skin protocols include both.

Norwegian Marine Collagen

Type I peptides that support skin elasticity, hydration and the strength of hair and nails.

Source. From a small family fishery in Lofoten sustainably harvesting wild cold-water cod from the same fjord their grandparents fished. Collagen is cold-extracted from the scales, slower and more expensive than heat processing, but it preserves the peptide structure that makes the compound biologically active.

How it works. Type I marine peptides are smaller than bovine collagen and absorb faster. Once circulating, they signal fibroblasts to upregulate the body's own collagen and hyaluronic acid synthesis.

Hyaluronic Acid

Holds up to a thousand times its weight in water, plumping skin and easing fine lines.

Source. Produced by bacterial fermentation in a Japanese facility, the cleanest and most studied source. We use a blend of low and high molecular weight HA so it works at the surface and the deeper layers of the skin.

How it works. Hyaluronic acid is a glycosaminoglycan naturally present in skin and joints. Topically and orally, it draws and binds water in connective tissue.
