Ingredient review
SH-Oligopeptide-75
INCI: SH-Oligopeptide-75, SH-Oligopeptide-1
A synthetic peptide blend that may help support collagen and reduce fine lines, but human data is still limited.
In plain English
Peptides are short chains of amino acids that act like messengers for your skin. SH-Oligopeptide-75 is a lab-made peptide that signals skin cells to behave more youthfully—think of it as a gentle nudge to produce more collagen and firm up. It's often paired with other peptides for a broader anti-aging effect.

Quick decision guide
Useful, but context matters
SH-Oligopeptide-75 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-75.
- 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 synthetic oligopeptide (short chain of amino acids) engineered to mimic natural signaling peptides in the skin. It is often combined with SH-Oligopeptide-1 in commercial blends.
How it works
When applied topically, the peptide is thought to bind to receptors on skin cells, triggering a cascade of signals that encourage collagen synthesis and reduce the breakdown of existing collagen. This can lead to firmer, smoother skin over time.
Pros
Low irritation
Most users can apply it daily without redness or stinging, making it suitable for sensitive skin.
Collagen support
It signals skin cells to produce more collagen, which can help maintain firmness and reduce fine lines over time.
Cons and cautions
Slow results
Visible improvements typically take weeks to months of consistent use, so patience is required.
Limited human data
Most evidence comes from lab studies or ingredient supplier tests, not large independent clinical trials.
Best for
- Adults looking for a gentle anti-aging peptide option
- Those with sensitive skin who want to avoid stronger actives like retinol
Use caution if
- Anyone allergic to any peptide ingredient (rare)
- Those expecting immediate or dramatic results
Usage tips
Safety summary
SH-Oligopeptide-75 is considered safe for topical cosmetic use at typical concentrations. Irritation and allergic reactions are rare. As with any new ingredient, a patch test is recommended.
Research notes
Evidence is primarily from in vitro studies and ingredient supplier data. Some small human studies on similar peptide blends show modest improvements in wrinkle depth and skin firmness, but independent peer-reviewed research on this specific peptide is limited.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for cosmetic use in the US, EU, and other major markets. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- Synthetic peptides are produced in labs with minimal environmental footprint compared to some natural extracts, but the manufacturing process uses chemical reagents.
Good to know
- Peptides are often listed as 'oligopeptide-X' or 'palmitoyl-X' on labels—SH-Oligopeptide-75 is a specific synthetic variant.
- This ingredient is often blended with other peptides in a single product to target multiple signs of aging.
