Ingredient review
SH-Oligopeptide-81 Amide
INCI: SH-Oligopeptide-81 Amide
A lab-made peptide amide that signals skin to firm and smooth, but long-term human data is still limited.
In plain English
This is a man-made peptide (a small chain of amino acids) that has been modified with an amide group to make it more stable and effective. In skincare, it acts like a messenger, telling skin cells to produce more collagen and other supportive proteins. Think of it as a gentle nudge to your skin's natural repair system, helping to reduce fine lines and improve firmness over time.

Quick decision guide
Useful, but context matters
SH-Oligopeptide-81 Amide 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-81 Amide.
- 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-81 Amide is a synthetic peptide, specifically an oligopeptide (a short chain of amino acids) that has been chemically modified with an amide group. This modification helps the peptide resist breakdown and better penetrate the skin's outer layer.
How it works
Once applied, the peptide is thought to bind to receptors on skin cells, triggering signals that increase collagen and elastin production. This helps strengthen the skin's support structure, leading to a firmer, smoother appearance. The amide modification improves stability and bioavailability compared to unmodified peptides.
Pros
Low irritation risk
As a synthetic peptide, it is generally non-irritating and suitable for sensitive skin types, unlike some active acids or retinoids.
Stable formulation
The amide modification makes the peptide more stable in skincare products, meaning it is less likely to degrade before you use it.
Cons and cautions
Limited human evidence
Most data comes from lab or animal studies; large-scale human trials on this exact peptide are scarce, so its real-world efficacy is not fully proven.
Gradual results
Peptides work slowly by supporting natural processes. You may need to use the product consistently for several weeks to see any visible change.
Best for
- Adults looking for gentle anti-aging support
- Those with sensitive skin who want a low-irritation peptide option
Use caution if
- Anyone with known allergies to synthetic peptides (rare)
- Those expecting instant, dramatic results
Usage tips
Safety summary
SH-Oligopeptide-81 Amide is considered safe for topical cosmetic use at typical concentrations. Irritation and allergy are rare. As with any new ingredient, patch testing is recommended for those with very sensitive skin.
Research notes
Evidence for this specific peptide is emerging. While peptide technology in general is well-supported for anti-aging benefits, direct human studies on SH-Oligopeptide-81 Amide are limited. Most support comes from analog studies and manufacturer data.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, but not approved as a drug. No specific regulatory warnings.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for plant or animal harvesting. Their environmental impact is considered low, though production energy use should be considered.
Good to know
- Peptides are often listed near the middle or end of ingredient lists because they are effective at low concentrations.
- The 'SH' prefix may refer to a specific proprietary sequence or supplier code.
