Ingredient review
RH-Polypeptide-82
INCI: RH-Polypeptide-82
A lab-made peptide that may help firm skin and soften lines, but research is still early and results vary.
In plain English
RH-Polypeptide-82 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 can make skin feel firmer and look smoother over time. Because it's a newer ingredient, most of the evidence comes from lab studies and small trials, so it's not a guaranteed fix but a promising addition to an anti-aging routine.

Quick decision guide
Useful, but context matters
RH-Polypeptide-82 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-82.
- 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 designed to resemble a naturally occurring protein fragment that signals skin cells to repair and rebuild.
How it works
It is believed to bind to receptors on skin cells (fibroblasts) and trigger them to increase production of collagen and other structural proteins, helping to plump and firm the skin from within.
Pros
Low irritation
RH-Polypeptide-82 is generally non-irritating and suitable for sensitive skin, unlike some stronger anti-aging actives like retinol.
Targeted signaling
It works by mimicking natural skin signals, which may support collagen production without causing inflammation or peeling.
Cons and cautions
Limited evidence
Most research is from lab studies or small trials; large-scale human studies are lacking, so effectiveness is not as well-established as for ingredients like retinoids or vitamin C.
Subtle results
Improvements in firmness and wrinkle reduction are typically gradual and modest, requiring consistent use over several months.
Best for
- People looking for a gentle anti-aging ingredient to add to their routine
- Those with mature or sun-damaged skin seeking improved firmness
Use caution if
- Anyone with a known allergy to synthetic peptides (rare)
- Those expecting immediate or dramatic results
Usage tips
Safety summary
RH-Polypeptide-82 has a low irritation and comedogenic risk based on its chemical structure and limited safety data. It is generally considered safe for topical use in cosmetics at typical concentrations.
Research notes
Early research suggests RH-Polypeptide-82 may stimulate collagen synthesis in vitro, but peer-reviewed human studies are sparse. More robust clinical trials are needed to confirm its efficacy and optimal usage.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on formulations
- Regulatory status
- Considered a cosmetic ingredient in most regions; not classified as a drug. No specific regulatory warnings.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in controlled lab conditions, which reduces environmental impact compared to animal-derived ingredients, but the production process is energy-intensive.
Good to know
- Peptides like RH-Polypeptide-82 are often combined with other anti-aging ingredients for a synergistic effect.
- Store products containing peptides away from direct sunlight and heat to maintain stability.
