Ingredient review
Bovine Polypeptide-1
INCI: SR-Bovine Polypeptide-1
A bovine-derived peptide that may support collagen and skin repair, but evidence is limited and ethical sourcing is a concern.
In plain English
This is a type of protein fragment (peptide) originally sourced from cows. In skincare, peptides are often used to signal skin cells to produce more collagen and repair damage. However, because it comes from an animal source, it raises questions about sustainability and ethics, and there isn't much modern research to confirm how well it works compared to plant-based or synthetic peptides.

Quick decision guide
Useful, but context matters
Bovine Polypeptide-1 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 Bovine Polypeptide-1.
- 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 peptide (short chain of amino acids) derived from bovine (cow) sources, used in cosmetic formulations for its potential to support skin structure and reduce signs of aging.
How it works
Peptides like this one are thought to work by mimicking natural signaling molecules in the skin, encouraging fibroblasts to produce more collagen and elastin. This can help improve skin firmness and reduce the appearance of fine lines over time.
Pros
Potential collagen support
As a peptide, it may help signal skin cells to produce more collagen, which can improve skin firmness and reduce fine lines over time.
Low irritation risk
Peptides are generally well-tolerated and unlikely to cause irritation, making them suitable for sensitive skin types.
Cons and cautions
Animal-derived source
Being bovine-derived, it is not suitable for vegans or those who prefer plant-based or synthetic ingredients, and raises ethical concerns about animal farming.
Limited evidence
There is little modern, peer-reviewed research specifically on SR-Bovine Polypeptide-1, so its effectiveness compared to other peptides is not well established.
Best for
- Those looking for anti-aging support
- Individuals interested in peptide-based skincare
Use caution if
- Vegans and vegetarians
- Those with ethical concerns about animal-derived ingredients
- People with known allergies to bovine proteins
Usage tips
Safety summary
Generally considered safe for topical use at low concentrations. However, individuals with allergies to bovine proteins should avoid it. The ingredient is not well-studied in modern clinical trials, so its long-term safety profile is less established than more common peptides.
Research notes
There is limited peer-reviewed research specifically on SR-Bovine Polypeptide-1. Most evidence for peptide efficacy comes from studies on other peptides like palmitoyl pentapeptide-4 or copper peptides. The ingredient's mechanism is theoretically similar, but direct evidence is lacking.
Common label clues
- Typical concentration
- Typically used at very low concentrations, often below 1%
- Regulatory status
- Approved for use in cosmetics in most regions, including the EU and US, but always check local regulations as animal-derived ingredients may have specific labeling requirements.
- Common uses
- Anti-aging serums, Eye creams, Facial moisturizers
- Environmental note
- Bovine-derived ingredients have a higher environmental footprint compared to synthetic or plant-based alternatives, due to resource use and emissions from livestock farming.
Good to know
- Peptides are generally more stable in pH-balanced formulations; avoid products with very low or high pH.
- If you prefer to avoid animal-derived ingredients, look for plant-based or synthetic peptide alternatives.
