Collagen
HumectantAnti-agingNaturalAlso known as: Hydrolyzed Collagen, Marine Collagen, Soluble Collagen
A structural protein that provides skin with firmness and elasticity. Topical collagen acts primarily as a humectant due to its large molecular size.
Routine placement
Serum · AM & PM
Time to results
Immediate hydration boost; 2-4 weeks for sustained improvement
Humectant, film-forming, improves skin feel, plumping effect from hydration.
Apply in serum or cream form. Topical collagen primarily works as a moisturizer, not a collagen replacement.
Topical collagen does not stimulate collagen production or replace lost collagen. Functions as a humectant. Hydrolyzed forms may have slightly better penetration.
- marine collagen: fish/shellfish allergy
Cautions
Topical collagen molecules are too large to penetrate skin and replace lost collagen. Benefits are primarily from surface hydration. Marketing often overstates effects.
What does Collagen do for skin?
Collagen is used in skincare primarily as a humectant ingredient. Its effects depend on concentration and formulation. Check the benefits section above for specific details.
Is Collagen safe for sensitive skin?
Collagen is generally well-tolerated, but sensitivity varies by individual. Start with a patch test if you have reactive skin, and introduce gradually into your routine.
Can I use Collagen every day?
For most skin types, daily use is appropriate at standard concentrations. If you experience any irritation, reduce frequency to every other day.

Related to Collagen
A versatile form of Vitamin B3 that strengthens the skin barrier, reduces pore appearance, controls oil production, and addresses multiple skin concerns.
A gentle alpha hydroxy acid derived from milk. Larger molecular size than glycolic acid means slower, more gentle penetration. Also has humectant properties.
The provitamin form of Vitamin B5 that deeply hydrates and helps repair the skin barrier. Converts to pantothenic acid in the skin.
The acid form of panthenol (provitamin B5). Supports skin barrier function, wound healing, and hydration.
Copper peptides, most commonly represented by the tripeptide-copper complex GHK-Cu, are small protein fragments bound to copper ions that occur naturally in human plasma, saliva, and urine. GHK-Cu plays a fundamental role in tissue remodeling by stimulating the synthesis of collagen, elastin, glycosaminoglycans, and other components of the extracellular matrix. In dermatology, copper peptides have attracted significant attention for their dual capacity to promote wound healing while simultaneously reducing the appearance of aging skin. The copper ion serves as a cofactor for lysyl oxidase, the enzyme responsible for cross-linking collagen and elastin fibers, while the GHK peptide sequence itself modulates gene expression related to tissue repair and anti-inflammatory pathways.
