Low-Molecular-Weight Marine Collagen Peptides

Low-Molecular-Weight Marine Collagen Peptides

Low-molecular-weight fish collagen peptides usually come from type I collagen in fish skin or scales. Average molecular weight is lower; hydroxyproline-containing oligopeptides enter the blood, leaning toward skin hydration.

Primary

Improve skin hydration

Fish-skin and fish-scale collagen is mainly type I. After enzymatic hydrolysis, average molecular weight is often lower, and hydroxyproline-containing fragments can still be measured in blood. People whose skin feels tight in dry climates more often see changes in hydration and dermal density after several continuous weeks.

Primary

Improve dermal elasticity

Type I collagen is the main dermal backbone. Fish collagen peptides supply absorbable oligopeptides, and fibroblast experiments can show upregulation of collagen-related expression. People who want to maintain facial elasticity more often see changes in firmness and the look of fine lines after continuous use.
