Ingredient review
RH-Polypeptide-87
INCI: RH-Polypeptide-87
A lab-made peptide that may help firm skin and soften wrinkles, but human studies are limited.
In plain English
RH-Polypeptide-87 is a short chain of amino acids (the building blocks of protein) made in a lab. In skincare, it's added to products like serums and creams with the goal of signaling skin cells to produce more collagen and elastin, which can make skin feel firmer and look smoother over time. Because it's a synthetic peptide, it's designed to be stable in formulas and gentle on skin.

Quick decision guide
Useful, but context matters
RH-Polypeptide-87 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 RH-Polypeptide-87.
- 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, specifically a recombinant human polypeptide, meaning it's engineered to mimic a fragment of a human protein involved in skin structure.
How it works
It is thought to work by penetrating the outer layer of skin and signaling fibroblasts (cells deep in the skin) to increase production of collagen and elastin, the proteins that give skin its firmness and bounce.
Pros
Gentle on skin
RH-Polypeptide-87 has a low irritation and comedogenic risk, making it suitable for sensitive or acne-prone skin types.
Targets aging signs
It is specifically designed to support collagen production, which can help improve skin firmness and reduce fine lines over time.
Cons and cautions
Limited human research
Most evidence comes from lab studies or small trials; large-scale human studies confirming its effectiveness are still emerging.
Subtle results
Peptides like this one typically produce gradual, modest improvements rather than dramatic changes, so patience is needed.
Best for
- Adults looking to support skin firmness and reduce early signs of aging
- Those with sensitive skin seeking a gentle anti-aging ingredient
Use caution if
- Anyone with a known allergy to synthetic peptides (rare)
- Those expecting dramatic, instant results—peptides work gradually
Usage tips
Safety summary
RH-Polypeptide-87 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, individual sensitivity is always possible.
Research notes
Evidence for RH-Polypeptide-87 is primarily based on its mechanism as a collagen-stimulating peptide. While similar peptides have shown promise in small studies, direct human clinical data for this specific ingredient is limited, placing its evidence level at 'emerging'.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- In the US, RH-Polypeptide-87 is regulated as a cosmetic ingredient and is not subject to FDA pre-market approval, but it must be safe for its intended use.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide produced via biotechnology, its environmental impact is generally lower than that of animal-derived ingredients, but manufacturing energy use should be considered.
Good to know
- Peptides are often listed low on ingredient lists because they are effective at very small concentrations.
- RH-Polypeptide-87 is a relatively new ingredient, so its long-term effects are still being studied.
