Ingredient review
Oligopeptide-73
INCI: Oligopeptide-73
Oligopeptide-73 is a synthetic peptide that may help reduce fine lines and improve skin firmness by signaling collagen production.
In plain English
Oligopeptide-73 is a short chain of amino acids (the building blocks of protein) made in a lab. In skincare, it acts like a messenger that tells your skin cells to produce more collagen and elastin, which are proteins that keep skin plump and firm. Think of it as a gentle nudge to your skin's natural repair system, helping to soften the look of wrinkles over time without harsh irritation.

Quick decision guide
Useful, but context matters
Oligopeptide-73 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-73.
- 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
Oligopeptide-73 is a synthetic peptide, meaning it's a small protein fragment created in a laboratory. It belongs to a class of ingredients called signal peptides, which are designed to mimic natural peptides in the skin that trigger collagen synthesis.
How it works
When applied topically, Oligopeptide-73 penetrates the outer layer of the skin and binds to specific receptors on fibroblasts (the cells that produce collagen). This binding sends a signal to ramp up collagen and elastin production, helping to strengthen the skin's support structure and reduce the appearance of fine lines and sagging.
Pros
Gentle on skin
Oligopeptide-73 has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Targeted anti-aging support
It specifically signals collagen production, which can help improve skin firmness and reduce fine lines over consistent use.
Cons and cautions
Gradual results
Unlike more potent ingredients like retinoids, Oligopeptide-73 works slowly and may take weeks to months to show visible improvement.
Less research than classics
Compared to well-studied peptides like Matrixyl, Oligopeptide-73 has fewer published clinical studies, so its efficacy is less established.
Best for
- Adults looking to reduce early signs of aging
- Those with sensitive skin seeking a gentle anti-aging option
Use caution if
- Anyone allergic to synthetic peptides (rare)
- Those expecting instant results
Usage tips
Safety summary
Oligopeptide-73 is considered safe for cosmetic use with a low risk of irritation or clogging pores. Patch testing is recommended for those with very sensitive skin, but adverse reactions are rare.
Research notes
Research on Oligopeptide-73 is limited compared to more established peptides. Early in vitro studies suggest it can stimulate collagen synthesis, but robust human clinical trials are lacking. Most evidence is extrapolated from the broader peptide category.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on products
- Regulatory status
- Oligopeptide-73 is a cosmetic ingredient regulated by the FDA as a cosmetic product component. It is not classified as a drug and is not intended to treat or prevent disease.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, Oligopeptide-73 is produced in controlled lab conditions, which reduces the environmental impact associated with harvesting natural ingredients. However, its production involves chemical synthesis, which may have a moderate carbon footprint.
Good to know
- Peptides like Oligopeptide-73 are often listed near the middle or end of ingredient lists because they are effective at low concentrations.
- This ingredient is water-soluble and works best in water-based serums rather than oil-based products.
