Ingredient review
Oligopeptide-107 / rh-Polypeptide-1
INCI: Oligopeptide-107, rh-Polypeptide-1
A lab-made peptide duo that may help reduce fine lines and improve skin firmness, but results vary and it works best in a consistent routine.
In plain English
Peptides are short chains of amino acids that act like messengers for your skin. Oligopeptide-107 and rh-Polypeptide-1 are made in a lab to mimic natural signals that tell skin cells to produce more collagen and repair damage. Think of them as tiny instructions that encourage your skin to look plumper and smoother over time. They are not hormones or drugs—they work gently on the surface and upper layers of skin.

Quick decision guide
Useful, but context matters
Oligopeptide-107 / rh-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 Oligopeptide-107 / rh-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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A combination of two synthetic peptides: Oligopeptide-107 (a copper-signaling peptide) and rh-Polypeptide-1 (a recombinant human-like polypeptide). Both are produced via biotechnology (fermentation) to ensure purity and consistency.
How it works
When applied to skin, these peptides bind to cell receptors and trigger signaling pathways that promote collagen synthesis, fibroblast activity, and tissue repair. They also help calm inflammation and support the skin's natural barrier function.
Pros
Gentle collagen support
Unlike harsh exfoliants or retinoids, this peptide blend works by signaling skin cells without causing peeling or irritation, making it suitable for sensitive skin.
Backed by biotechnology
Produced via fermentation, these peptides are highly pure and consistent, reducing the risk of contaminants found in some natural extracts.
Cons and cautions
Slow, subtle results
You won't see a dramatic change overnight. It takes weeks to months of daily use to notice any difference in fine lines or firmness.
Premium price tag
Products containing this peptide blend tend to be more expensive than basic moisturizers, and the benefit may not justify the cost for everyone.
Best for
- Adults looking for a gentle anti-aging ingredient that supports collagen
- People with sensitive or reactive skin who want to avoid strong actives
Use caution if
- Those expecting instant or dramatic results (peptides are subtle and slow)
- Anyone with a known allergy to any peptide or copper compound
Usage tips
Safety summary
Oligopeptide-107 and rh-Polypeptide-1 are considered safe for topical use in cosmetics at typical concentrations. They are non-irritating and non-sensitizing for most people. As with any ingredient, patch test before first use if you have sensitive skin.
Research notes
Peptides in general have moderate evidence supporting their ability to stimulate collagen production and improve skin appearance in clinical studies. However, specific data on this exact blend is limited, and most evidence comes from studies on similar copper and signal peptides.
Common label clues
- Typical concentration
- 0.001% to 0.1% (very low, as peptides are potent at tiny amounts)
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU. Not classified as a drug or active pharmaceutical ingredient.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- Produced via fermentation using renewable resources, which has a lower environmental footprint than extraction from animal or plant sources.
Good to know
- Peptides are fragile—avoid using them right after strong acids or exfoliants that can break them down.
- This ingredient is often listed near the end of an ingredient list because it's effective at very low concentrations.
