Ingredient review
Ursoloyl Tripeptide-35
INCI: Ursoloyl Tripeptide-35
A synthetic peptide that may help improve skin firmness and smooth fine lines, but research is still emerging.
In plain English
Ursoloyl Tripeptide-35 is a lab-made peptide (a small chain of amino acids) that is attached to ursolic acid, a plant-derived compound. In skincare, it is meant to signal skin cells to produce more collagen and elastin, which can help make skin look firmer and reduce the appearance of wrinkles. Because it is a newer ingredient, most of the evidence comes from lab studies and manufacturer data rather than large human trials.

Quick decision guide
Useful, but context matters
Ursoloyl Tripeptide-35 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 Ursoloyl Tripeptide-35.
- 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 conjugate combining a tripeptide (three amino acids) with ursolic acid, designed to mimic natural signaling molecules that encourage collagen production.
How it works
When applied to the skin, the peptide portion is thought to bind to cell receptors and stimulate fibroblasts to produce more collagen and elastin. The ursolic acid component may also provide antioxidant and anti-inflammatory support, helping to protect existing collagen from breakdown.
Pros
Gentle anti-aging support
Ursoloyl Tripeptide-35 is considered very gentle on the skin, making it a good option for people who find retinol or acids too irritating.
Targets collagen production
By signaling skin cells to produce more collagen, it may help improve skin firmness over time without causing redness or peeling.
Cons and cautions
Limited human research
Most evidence comes from lab studies or manufacturer claims, so it is unclear how well it works in real-world use compared to more established anti-aging ingredients.
Results take time
Like most peptides, noticeable improvements in firmness and wrinkles typically require consistent use over several weeks to months.
Best for
- Adults looking for a gentle anti-aging ingredient
- Those with sensitive skin who cannot tolerate stronger actives like retinol
Use caution if
- Anyone with a known allergy to peptides or ursolic acid
Usage tips
Safety summary
Ursoloyl Tripeptide-35 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, though individual sensitivities are possible.
Research notes
Evidence is primarily from in vitro studies and manufacturer-sponsored research. Independent clinical trials on humans are scarce, so the ingredient's efficacy is not as well-established as that of more studied peptides or retinoids.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. Not classified as a drug.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in labs and have a moderate environmental footprint; no specific sustainability data is available for this ingredient.
Good to know
- Peptides are generally stable in water-based formulas but can degrade in very low pH products.
- Ursoloyl Tripeptide-35 is often found in anti-aging serums and eye creams.
