Ingredient review
Acetyl SH-Oligopeptide-77 Amide
INCI: Acetyl SH-Oligopeptide-77 Amide
A lab-made peptide that may help firm skin and soften fine lines, but research is still early.
In plain English
This is a man-made protein fragment (peptide) that is added to skincare products to help support the skin's structure. Think of it as a tiny signal that tells skin cells to behave more youthfully. Because it's a large molecule, it stays mostly on the skin's surface, where it can help improve firmness and reduce the look of wrinkles over time.
Quick decision guide
Useful, but context matters
Acetyl SH-Oligopeptide-77 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 Acetyl SH-Oligopeptide-77 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
Acetyl SH-Oligopeptide-77 Amide is a synthetic peptide, meaning it's a short chain of amino acids created in a lab. The 'acetyl' part helps it stay stable in formulas, and 'amide' indicates a specific chemical modification. It belongs to a class of ingredients called signal peptides, which are designed to mimic natural skin signals.
How it works
In a cosmetic product, this peptide is believed to interact with skin cells on the surface, encouraging them to produce more collagen and other supportive proteins. By doing so, it may help improve skin firmness and reduce the appearance of fine lines and wrinkles. However, because peptides are large, they do not deeply penetrate the skin, so effects are gradual and subtle.
Pros
Gentle on skin
This peptide has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Targeted anti-aging support
It specifically aims to support collagen production, which can help improve skin firmness and reduce fine lines over time.
Cons and cautions
Limited evidence
There is very little published research on Acetyl SH-Oligopeptide-77 Amide specifically, so its effectiveness is not as well-established as other peptides.
Subtle results
Like most peptides, the effects are gradual and mild. You won't see dramatic changes overnight, and results depend on consistent use over weeks or months.
Best for
- People looking for gentle anti-aging support
- Those with normal to dry skin who want extra firmness
Use caution if
- Anyone with a known allergy to peptides (rare)
- Those expecting dramatic, instant results
Usage tips
Safety summary
Acetyl SH-Oligopeptide-77 Amide is considered safe for topical cosmetic use at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types. As with any new ingredient, a patch test is recommended for those with very sensitive skin.
Research notes
Research on this specific peptide is limited. Most evidence comes from ingredient supplier studies and general knowledge about signal peptides. While the concept is promising, independent peer-reviewed studies are lacking. Users should have realistic expectations about subtle, gradual improvements.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on formulations
- Regulatory status
- Approved for cosmetic use in most regions including the EU and US. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, it is produced in controlled lab conditions, which reduces environmental impact compared to some natural extracts. However, its biodegradability is not well-documented.
Good to know
- Peptides are often combined with other anti-aging ingredients like niacinamide or vitamin C for complementary benefits.
- This ingredient is synthetic, so it is suitable for vegan and cruelty-free routines.
