Ingredient review
SH-Oligopeptide-73 Amide Acetate
INCI: SH-Oligopeptide-73 Amide Acetate
A lab-made peptide that may help firm skin and soften fine lines, but research is still emerging and results vary.
In plain English
This is a synthetic peptide, which is a short chain of amino acids (the building blocks of proteins). In skincare, peptides act like messengers that tell your skin cells to produce more collagen and elastin, the proteins that keep skin plump and firm. SH-Oligopeptide-73 Amide Acetate is a specific peptide designed to be stable and effective in creams and serums. It's not a miracle worker, but with regular use, it may help improve skin texture and reduce the appearance of fine lines over time.

Quick decision guide
Useful, but context matters
SH-Oligopeptide-73 Amide Acetate 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 Amide Acetate.
- 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 peptide (short protein fragment) modified with an amide group and acetate salt to improve stability and skin penetration. It is designed to mimic natural signaling molecules that encourage collagen synthesis.
How it works
When applied topically, the peptide is thought to bind to receptors on skin cells (fibroblasts), triggering a cascade that boosts collagen and elastin production. This can help strengthen the skin's structure, leading to firmer, smoother skin over weeks of consistent use.
Pros
Gentle anti-aging support
Unlike stronger actives like retinol, this peptide is unlikely to cause peeling or redness, making it suitable for sensitive skin types.
Stable formulation
The amide and acetate modifications help the peptide stay effective in skincare products longer, so you get more benefit from each application.
Cons and cautions
Gradual results
You'll need to use the product consistently for several weeks to see any visible improvement in fine lines or firmness.
Limited independent research
Most evidence comes from the manufacturer's studies, and there are few peer-reviewed human trials specifically on SH-Oligopeptide-73 Amide Acetate.
Best for
- Adults looking for gentle anti-aging support
- Those with fine lines or loss of firmness who want a non-irritating option
Use caution if
- Individuals with known peptide allergies (rare)
- Those expecting instant or dramatic results
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Rare reports of mild irritation. No known toxicity or systemic absorption concerns based on current data.
Research notes
Peptides in general have moderate evidence for anti-aging benefits. Specific studies on SH-Oligopeptide-73 Amide Acetate are limited to manufacturer-funded research and a few small clinical trials. More independent studies are needed.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved as a cosmetic ingredient in the US, EU, and other major markets. Not classified as a drug; claims must avoid medical language.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetically produced in labs, so it does not rely on animal or plant harvesting. Manufacturing has a moderate carbon footprint typical of lab-based ingredients.
Good to know
- Peptides work best when combined with other anti-aging ingredients like antioxidants (vitamin C) and sunscreen.
- This peptide is often found in high-end serums but is becoming more common in drugstore products.
