Ingredient review
SH-Oligopeptide-73
INCI: SH-Oligopeptide-73
A promising synthetic peptide that may help firm skin and reduce fine lines, but research is still limited compared to more established peptides.
In plain English
SH-Oligopeptide-73 is a man-made protein fragment designed to signal skin cells to produce more collagen and elastin. Think of it as a tiny messenger that tells your skin to act younger and firmer. It's often used in anti-aging products, but because it's relatively new, there's less scientific proof of its effectiveness compared to older peptides like Matrixyl.

Quick decision guide
Useful, but context matters
SH-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 SH-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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
SH-Oligopeptide-73 is a synthetic peptide, meaning it's a short chain of amino acids created in a lab. It belongs to a class of ingredients called signal peptides, which are designed to mimic natural proteins in the skin and trigger beneficial responses like collagen synthesis.
How it works
When applied topically, SH-Oligopeptide-73 is believed to bind to receptors on skin cells (fibroblasts) and stimulate them to produce more collagen and elastin. This can help improve skin firmness, reduce the appearance of fine lines and wrinkles, and support the skin's structural integrity over time.
Pros
Low irritation potential
SH-Oligopeptide-73 is generally non-irritating and suitable for most skin types, including sensitive skin, making it a gentle anti-aging option.
Targeted anti-aging action
It specifically signals collagen production, which can help improve skin firmness and reduce fine lines over time, offering a more targeted approach than some broad moisturizers.
Cons and cautions
Limited research
Compared to well-studied peptides like Matrixyl, SH-Oligopeptide-73 has fewer published studies and less evidence supporting its efficacy, so results may be less predictable.
Gradual results
Peptides work slowly, and it may take weeks to months of consistent use to see visible improvements, which can be discouraging for those wanting quick changes.
Best for
- Adults looking for anti-aging benefits
- Those with normal to dry skin seeking firmness
Use caution if
- Anyone with known peptide allergies
- Those seeking immediate or dramatic results (peptides work gradually)
Usage tips
Safety summary
SH-Oligopeptide-73 is considered safe for topical use in cosmetics at typical concentrations. It has a low risk of irritation and is not known to be comedogenic. However, as with any new ingredient, patch testing is recommended for those with very sensitive skin or allergies.
Research notes
Research on SH-Oligopeptide-73 is limited, with most evidence coming from in vitro studies and small-scale trials. While it shows promise for collagen stimulation, larger human studies are needed to confirm its efficacy and compare it to more established peptides.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved for cosmetic use in the US, EU, and other major markets; not regulated as a drug.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for natural resource extraction, but their manufacturing process may involve chemical solvents.
Good to know
- SH-Oligopeptide-73 is often combined with other peptides or antioxidants for synergistic effects.
- It is water-soluble and typically found in serum or gel-based formulas.
