Fish-derived proteins and peptides show antioxidant, anti-aging, and skin-repair properties that make them promising ingredients for cosmeceutical products, with the added benefit of being sourced from fish processing waste.
Sourced from fish processing wasteThe peptides reviewed are largely derived from fish skins, scales, and other by-products that would otherwise be discarded — making them both a scientific and sustainability story.
What the researchers found
Marine fish-derived proteins and peptides — particularly those obtained from enzymatic hydrolysis of fish processing by-products — show a broad range of activities relevant to skincare: antioxidant, antimicrobial, anti-aging, anti-photoaging, and matrix metalloproteinase (MMP) inhibition. Fish-derived collagen specifically demonstrates abilities in skin repair and tissue regeneration.
The review highlights that these peptides are increasingly being developed into cosmeceutical products, taking advantage of both their bioactivity and the sustainability angle of using fish processing waste as the raw material.
Why it matters
The cosmeceutical industry is rapidly adopting marine-derived peptides as alternatives to synthetic ingredients. Fish collagen peptides are particularly appealing because they're biocompatible, can be sourced sustainably from processing waste, and avoid the religious and cultural concerns associated with bovine or porcine collagen. This review maps the landscape of what's available and what activities have been demonstrated.

How the study worked
Narrative review synthesizing published literature on marine fish-derived proteins and peptides, covering isolation methods (chemical and enzymatic hydrolysis), bioactive properties, and cosmeceutical applications.
Who was studied
Review of laboratory and preclinical studies (no human clinical data)
What this study cannot tell us
Narrative review without systematic methodology. Most evidence cited is from in vitro or preclinical studies. Clinical evidence for cosmeceutical efficacy in humans is limited. The review does not critically assess study quality or provide effect size comparisons. Bioavailability and penetration through human skin are not deeply addressed.
How to read the evidence
Rated low: narrative review covering mostly in vitro and preclinical studies. While it provides a useful industry overview, there is limited clinical evidence for the cosmeceutical claims discussed.
When this study was published
Published in 2017. The marine collagen market has grown significantly since then, with more products available. However, the fundamental bioactivity data reviewed here remains relevant as the scientific foundation for current products.
The bigger picture
Marine collagen is now one of the fastest-growing segments of the collagen supplement and skincare market. This review captures why: fish-derived peptides offer a unique combination of bioactivity, sustainability (using waste from the fishing industry), and broader cultural acceptability compared to bovine or porcine sources. As the clean beauty and sustainable sourcing movements accelerate, marine peptides are positioned to become even more prominent in cosmeceutical formulations.
Questions still open
- Do marine fish collagen peptides actually penetrate human skin deeply enough to produce anti-aging effects when applied topically?
- How do fish-derived collagen peptides compare to bovine or synthetic peptides in controlled human trials?
- Can enzymatic hydrolysis methods be standardized to ensure consistent bioactivity across commercial products?
Common questions
What makes fish-derived collagen peptides different from regular collagen supplements?
Do marine fish peptides actually work in skincare products?
