Ingredient review
Ursoloyl Tetrapeptide-37
INCI: Ursoloyl Tetrapeptide-37
A synthetic peptide that may help improve skin firmness and smoothness, but research is still emerging.
In plain English
Ursoloyl Tetrapeptide-37 is a lab-made peptide (a small chain of amino acids) that is added to skincare products to help support the skin's structure. It is thought to work by signaling skin cells to produce more collagen and other supportive proteins, which can help reduce the appearance of fine lines and improve firmness over time. Because it is a newer ingredient, the amount of published research is limited, but early studies and ingredient suppliers suggest it can be a gentle addition to anti-aging routines.

Quick decision guide
Useful, but context matters
Ursoloyl Tetrapeptide-37 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 Tetrapeptide-37.
- 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
Ursoloyl Tetrapeptide-37 is a synthetic peptide, meaning it is a short chain of amino acids created in a laboratory. It is designed to mimic naturally occurring signaling peptides that tell skin cells to build more collagen and elastin, the proteins that keep skin plump and firm.
How it works
When applied topically, the peptide is thought to bind to receptors on skin cells and trigger a cascade of signals that increase collagen production. Over time, this can help improve skin density, reduce the depth of wrinkles, and enhance overall firmness. It is typically used in leave-on products like serums and creams so it has time to absorb and interact with the skin.
Pros
Gentle anti-aging support
Ursoloyl Tetrapeptide-37 is considered low-risk for irritation, making it suitable for sensitive skin types that cannot tolerate stronger actives like retinoids.
Targets firmness and wrinkles
By signaling collagen production, this peptide may help improve skin density and reduce the look of fine lines with regular use over several weeks.
Cons and cautions
Limited independent research
Most evidence comes from ingredient suppliers rather than peer-reviewed studies, so the full efficacy and long-term benefits are not yet well established.
Slow, gradual results
Peptides work by signaling cellular processes, so visible improvements typically take 8–12 weeks of consistent use, which may be too slow for some users.
Best for
- Adults looking to improve skin firmness and reduce early signs of aging
- People with normal to dry skin who want a gentle anti-aging option
Use caution if
- Those with known allergies to synthetic peptides (rare) should patch test first
Usage tips
Safety summary
Ursoloyl Tetrapeptide-37 is considered safe for topical cosmetic use at typical concentrations. Irritation and allergy are rare, but a patch test is recommended for those with very sensitive skin or known peptide allergies.
Research notes
Research on Ursoloyl Tetrapeptide-37 specifically is limited. Most supporting data comes from supplier studies and broader peptide research. Early evidence suggests it may support collagen synthesis, but more independent clinical trials are needed to confirm its efficacy.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on formulations
- Regulatory status
- Approved for cosmetic use in the US and EU as a skin conditioning agent. Not classified as a drug.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in controlled laboratory settings, which reduces the environmental impact compared to harvesting from natural sources.
Good to know
- Peptides are generally more stable when formulated at a pH between 5 and 7.
- Ursoloyl Tetrapeptide-37 is often combined with other peptides or antioxidants in anti-aging formulas.
