Ingredient review
RH-Polypeptide-60
INCI: RH-Polypeptide-60
RH-Polypeptide-60 is a lab-made peptide that may help firm skin and soften fine lines, but research is still early and results vary.
In plain English
RH-Polypeptide-60 is a short chain of amino acids (the building blocks of protein) made in a lab to mimic natural signaling molecules in your skin. When applied in a cream or serum, it's thought to encourage skin cells to produce more collagen and elastin, which are the proteins that keep skin plump and bouncy. Think of it as a tiny messenger that tells your skin to act younger. Because it's a large molecule, it works best in formulas designed to help it penetrate the outer layer of skin.

Quick decision guide
Useful, but context matters
RH-Polypeptide-60 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-60.
- 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
RH-Polypeptide-60 is a synthetic peptide, specifically a recombinant human polypeptide, meaning it's produced by biotechnology to match a natural human protein fragment. It belongs to a class of ingredients called signal peptides, which are used in anti-aging skincare to mimic the body's own repair signals.
How it works
In a cosmetic product, RH-Polypeptide-60 is believed to bind to receptors on skin cells (fibroblasts) and trigger a cascade of signals that increase the production of collagen, elastin, and other structural proteins. This can help improve skin firmness, reduce the appearance of fine lines, and support the skin's overall repair process. However, because peptides are large, they need to be formulated with penetration enhancers or delivered in a stable vehicle to reach deeper skin layers effectively.
Pros
Targeted anti-aging action
Specifically designed to signal collagen production, which can help improve skin firmness and reduce fine lines over time.
Generally well-tolerated
As a biotech ingredient, it's typically non-irritating and suitable for most skin types, including sensitive skin when properly formulated.
Cons and cautions
Limited research
Compared to well-known peptides like Matrixyl, RH-Polypeptide-60 has fewer published human studies, so its effectiveness is less certain.
Variable results
The peptide's large size means it may not penetrate deeply in all formulations, leading to inconsistent benefits depending on the product.
Best for
- Adults looking for anti-aging support
- People with mild to moderate skin laxity or fine lines
Use caution if
- Those with very sensitive skin who react to many active ingredients (patch test recommended)
- Anyone seeking immediate, dramatic results (peptides work gradually)
Usage tips
Safety summary
RH-Polypeptide-60 is considered safe for topical cosmetic use at typical concentrations. It is non-toxic, non-irritating, and non-sensitizing in standard tests. However, individual sensitivity is always possible, so a patch test is recommended for new users.
Research notes
Evidence for RH-Polypeptide-60 is primarily based on in vitro (lab) studies and manufacturer-sponsored trials showing increased collagen synthesis. Independent peer-reviewed human studies are limited, placing its evidence level at 'emerging' rather than 'strong'.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products
- Regulatory status
- Approved for cosmetic use in the US, EU, and other major markets as a skin conditioning agent. Not classified as a drug.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Produced via biotechnology (fermentation), which generally has a lower environmental footprint than animal-derived ingredients, but specific sourcing varies by manufacturer.
Good to know
- Peptides are fragile; avoid using with very low pH (acidic) products in the same routine
- Store products containing peptides in a cool, dark place to maintain stability
