Ingredient review
RH-Polypeptide-88
INCI: RH-Polypeptide-88
RH-Polypeptide-88 is a lab-made peptide that may help firm skin and soften lines, but research is still limited compared to more established peptides.
In plain English
Peptides are short chains of amino acids that act like messengers for your skin cells. RH-Polypeptide-88 is a specific synthetic peptide designed to signal skin to produce more collagen and elastin, the proteins that keep skin plump and springy. Think of it as a gentle nudge to your skin's natural repair system.

Quick decision guide
Useful, but context matters
RH-Polypeptide-88 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-88.
- 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 produced through biotechnology, mimicking a fragment of human collagen to encourage skin's own collagen production.
How it works
When applied topically, RH-Polypeptide-88 is thought to bind to receptors on skin cells and trigger a signaling cascade that boosts collagen and elastin synthesis, helping to improve skin firmness and reduce the depth of wrinkles over time.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive skin types.
Supports natural collagen
Works with your skin's own biology to encourage firmness, rather than forcing a reaction.
Cons and cautions
Limited research
Fewer peer-reviewed studies exist for RH-Polypeptide-88 compared to classic anti-aging peptides, so its efficacy is less certain.
Gradual results
Visible improvements typically take weeks to months of consistent use, and results are subtle.
Best for
- Individuals looking for a gentle anti-aging ingredient
- Those with sensitive skin who want to avoid strong actives like retinol
Use caution if
- Anyone seeking immediate or dramatic results (peptides work gradually)
- Those allergic to any component of the peptide complex
Usage tips
Safety summary
RH-Polypeptide-88 is considered safe for topical cosmetic use. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any new ingredient, patch testing is recommended.
Research notes
Evidence for RH-Polypeptide-88 is emerging. While peptide technology in general is well-supported for anti-aging, specific clinical trials for this exact peptide are limited. Most data come from manufacturer studies and broader peptide research.
Common label clues
- Typical concentration
- Typically 0.5% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used as directed. Not a drug ingredient.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced via fermentation or chemical synthesis, which has a lower environmental footprint than animal-derived alternatives.
Good to know
- Peptides are most effective when formulated at the right pH and with proper delivery systems.
- RH-Polypeptide-88 is often combined with other peptides or antioxidants for synergistic effects.
