Ingredient review
Transgenic Rice Rh-Polypeptide-45
INCI: TRANSGENIC RICE RH-POLYPEPTIDE-45
A biotech rice peptide that may support collagen and skin firmness, but human research is still limited.
In plain English
This is a lab-made protein fragment (peptide) produced by genetically modified rice. In skincare, peptides are like tiny signals that tell skin cells to produce more collagen and repair damage. Because it comes from rice, it's generally gentle and unlikely to irritate, but because it's new, we don't have a lot of human studies yet to confirm how well it works compared to more established peptides.

Quick decision guide
Useful, but context matters
Transgenic Rice Rh-Polypeptide-45 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 Transgenic Rice Rh-Polypeptide-45.
- 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 polypeptide (a chain of amino acids) produced by transgenic rice plants. It is designed to mimic natural signaling peptides that encourage collagen synthesis and skin repair.
How it works
When applied to skin, the peptide is thought to bind to cell receptors and trigger signals that boost collagen production and support the skin's extracellular matrix, potentially reducing fine lines and improving firmness over time.
Pros
Gentle on skin
Low irritation and comedogenic risk makes it suitable for sensitive skin types.
Novel biotech approach
Produced via transgenic rice, which can be more sustainable than animal-derived peptides.
Cons and cautions
Limited research
Most evidence comes from lab studies; robust human trials are scarce, so real-world efficacy is less certain.
Premium price
Biotech production often makes this ingredient more expensive than traditional peptides.
Best for
- People looking for gentle anti-aging ingredients
- Those with sensitive skin who want to try peptides
Use caution if
- Anyone with a known allergy to rice-derived ingredients
- Those seeking proven, extensively studied anti-aging actives
Usage tips
Safety summary
Current data suggests low irritation and allergy risk, but long-term safety data is limited due to its novelty. Patch testing is recommended for first-time use.
Research notes
Preliminary in vitro studies indicate potential collagen-stimulating activity, but peer-reviewed human clinical studies are lacking. More research is needed to confirm anti-aging benefits.
Common label clues
- Typical concentration
- Typically 0.1% to 1% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used as directed, though it is not a drug ingredient.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Produced via plant biotechnology, which can reduce reliance on animal sources and lower environmental footprint compared to some synthetic peptides.
Good to know
- This ingredient is not the same as plain rice extract or rice water; it's a specific engineered peptide.
- It may be listed under different trade names in product ingredient lists.
