Ingredient review
SH-Polypeptide-69
INCI: SH-Polypeptide-69
SH-Polypeptide-69 is a lab-made peptide that may help signal skin to produce more collagen, but research is still early and results vary.
In plain English
SH-Polypeptide-69 is a short chain of amino acids (the building blocks of protein) made in a lab. When applied to skin, it's thought to act like a messenger, telling skin cells to produce more collagen and elastin. This can help reduce the look of fine lines and improve firmness over time. Because it's a newer ingredient, there's less long-term data compared to well-studied peptides like Matrixyl.

Quick decision guide
Useful, but context matters
SH-Polypeptide-69 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-Polypeptide-69.
- 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-Polypeptide-69 is a synthetic peptide, meaning it's a man-made chain of amino acids designed to mimic natural signaling molecules in the skin. It belongs to a class of ingredients called 'signal peptides' that are intended to encourage collagen production.
How it works
In a cosmetic product, SH-Polypeptide-69 is absorbed into the upper layers of the skin. It is believed to bind to receptors on fibroblasts (the cells that make collagen) and trigger them to produce more collagen and other structural proteins. This can help plump the skin and reduce the appearance of wrinkles over weeks of consistent use.
Pros
Targeted anti-aging support
SH-Polypeptide-69 is designed to specifically encourage collagen production, which can help improve skin firmness and reduce fine lines over time.
Low irritation potential
As a synthetic peptide, it is generally well-tolerated by most skin types, including sensitive skin, with a low risk of irritation or clogged pores.
Cons and cautions
Limited research
Compared to well-established peptides like Matrixyl, SH-Polypeptide-69 has fewer published human studies, so its effectiveness is less certain.
Subtle, gradual results
Peptides work slowly. You may need to use a product consistently for 8–12 weeks before noticing visible improvements, and results are typically modest.
Best for
- People looking for gentle anti-aging support
- Those with mature or sun-damaged skin wanting improved firmness
Use caution if
- Anyone with known allergies to synthetic peptides (rare)
- Those expecting immediate, dramatic results
Usage tips
Safety summary
SH-Polypeptide-69 is considered safe for cosmetic use at typical concentrations. It has 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 SH-Polypeptide-69 is still emerging. Early in vitro studies suggest it can stimulate collagen synthesis, but robust human clinical trials are lacking. It is less studied than classic peptides like Matrixyl or copper peptides.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on formulations
- Regulatory status
- SH-Polypeptide-69 is a cosmetic ingredient regulated as a cosmetic active in most regions. It is not a drug and is not intended to treat or prevent disease.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- As a synthetic peptide, its production involves chemical synthesis, which may have a moderate environmental footprint compared to naturally derived alternatives.
Good to know
- Peptides work best when used consistently over time; don't expect overnight changes.
- SH-Polypeptide-69 is often combined with other anti-aging ingredients like niacinamide or hyaluronic acid for added benefits.
