Ingredient review
Jellyfish Polypeptide-1
INCI: SR-Jellyfish Polypeptide-1
A marine-inspired peptide that may help hydrate and firm skin, but human research is still limited.
In plain English
Jellyfish Polypeptide-1 is a lab-made protein fragment modeled after compounds found in jellyfish. In skincare, it's added to help attract moisture to the skin and support a smoother, firmer look. Think of it as a gentle hydrating and plumping ingredient, though it's not as well-studied as some classic peptides.

Quick decision guide
Useful, but context matters
Jellyfish Polypeptide-1 is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Jellyfish Polypeptide-1.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic peptide (short chain of amino acids) designed to mimic the structure of proteins naturally found in jellyfish. It is produced through biotechnology, not harvested from animals.
How it works
It is believed to form a thin film on the skin that helps reduce water loss, while also signaling skin cells to boost collagen production. This dual action can lead to temporary plumping and improved skin texture over time.
Pros
Gentle hydration
Forms a light film on skin to lock in moisture without feeling heavy, making it suitable for most skin types.
Novel anti-aging approach
Offers a unique marine-inspired peptide option for those seeking alternatives to traditional anti-aging ingredients.
Cons and cautions
Limited research
Most evidence comes from lab or animal studies; robust human trials are scarce, so effectiveness is not fully proven.
Premium price
As a specialty biotech ingredient, products containing it tend to be more expensive than those with well-established peptides.
Best for
- Anyone looking for a gentle anti-aging peptide with hydrating properties
- People with dry or dehydrated skin who want extra moisture retention
Use caution if
- Those with a known allergy to marine-derived ingredients (though this is synthetic, caution is advised)
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Irritation and allergy are rare, but patch testing is recommended for sensitive individuals.
Research notes
Early studies suggest potential for hydration and collagen support, but peer-reviewed human data is minimal. More research is needed to confirm long-term benefits.
Common label clues
- Typical concentration
- 0.1% to 1% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in most regions, including the EU and US, with no specific restrictions.
- Common uses
- Anti-aging serums, Moisturizers, Eye creams
- Environmental note
- Being synthetic and produced via biotechnology, it avoids the ecological concerns of harvesting marine life.
Good to know
- This ingredient is not derived from jellyfish; it's made in a lab using biotechnology.
- It is often combined with other peptides or hyaluronic acid for enhanced effects.
