Ingredient review
Nematode Rh-Polypeptide-47
INCI: NEMATODE RH-POLYPEPTIDE-47
A novel biotech peptide that shows promise for anti-aging, but human research is still limited.
In plain English
This is a lab-made protein fragment (peptide) modeled after a substance found in nematodes (tiny roundworms). In skincare, it's used to signal skin cells to produce more collagen and elastin, which can help reduce fine lines and improve firmness. Because it's made in a lab, it's consistent and doesn't involve any animal-derived ingredients.

Quick decision guide
Useful, but context matters
Nematode Rh-Polypeptide-47 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 Nematode Rh-Polypeptide-47.
- 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 recombinant peptide produced through biotechnology, derived from a protein sequence found in nematodes. It is a signaling peptide designed to mimic natural skin-repair processes.
How it works
When applied to the skin, the peptide is thought to bind to cell receptors and trigger a cascade of signals that encourage fibroblasts to produce more collagen and elastin. This can help strengthen the skin's support structure, leading to a firmer, more youthful appearance over time.
Pros
Novel anti-aging potential
As a signaling peptide, it may help boost collagen and elastin, which can improve skin firmness and reduce wrinkles over time.
Biotech purity
Being lab-made, it avoids animal-derived concerns and offers consistent quality batch to batch.
Cons and cautions
Limited human research
Most evidence comes from lab or animal studies; large-scale human trials are not yet available, so real-world effectiveness is less certain.
Stability challenges
Peptides can be fragile and may degrade in formulas if not properly stabilized, which can reduce their effectiveness.
Best for
- Adults looking for anti-aging support with a novel peptide
- Those interested in biotech-derived, non-animal ingredients
Use caution if
- Anyone with a known allergy to peptides or biotech-derived ingredients (rare)
Usage tips
Safety summary
Based on available data, Nematode Rh-Polypeptide-47 appears to have low irritation and comedogenic risk. However, long-term safety data in humans is limited, so patch testing is recommended for new users.
Research notes
Research is in early stages. In vitro studies suggest collagen-stimulating activity, but peer-reviewed human clinical trials are scarce. The ingredient is considered promising but not yet proven.
Common label clues
- Typical concentration
- Typically 0.1% to 1% in leave-on products
- Regulatory status
- Generally considered a cosmetic ingredient; not approved as a drug. Regulations vary by country, but it is allowed in cosmetics in the US and EU.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Biotech production typically has a lower environmental footprint than animal-derived ingredients, but energy use in fermentation processes can vary.
Good to know
- This peptide is not derived from nematodes themselves; it's a synthetic copy of a protein fragment.
- Peptides work best when used consistently over several weeks or months.
