Ingredient review
Palmitoyl SH-Tripeptide-1 Amide
INCI: PALMITOYL SH-TRIPEPTIDE-1 AMIDE
A synthetic peptide that may help reduce the appearance of fine lines and improve skin firmness, but results are gradual and vary by person.
In plain English
Palmitoyl SH-Tripeptide-1 Amide is a lab-made protein fragment (a peptide) that signals your skin to produce more collagen, the protein that keeps skin plump and firm. It's often added to anti-aging products to help soften fine lines over time. Think of it as a gentle nudge to your skin's natural repair system.

Quick decision guide
Useful, but context matters
Palmitoyl SH-Tripeptide-1 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 Palmitoyl SH-Tripeptide-1 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic peptide consisting of a short chain of amino acids (tripeptide) attached to a palmitic acid molecule, which helps it penetrate the skin more effectively. It is a variant of the well-studied Matrixyl peptide family.
How it works
Once applied, the palmitic acid tail helps the peptide absorb into the upper layers of skin. There, the tripeptide portion mimics a natural collagen fragment, signaling skin cells to ramp up collagen and other matrix proteins. This can lead to firmer, smoother skin over weeks of consistent use.
Pros
Gentle anti-aging support
Palmitoyl SH-Tripeptide-1 Amide is well-tolerated by most skin types, including sensitive skin, making it a milder alternative to stronger actives like retinol.
Backed by peptide research
Peptides like this one have been studied for their ability to stimulate collagen production, offering a science-based approach to reducing fine lines.
Cons and cautions
Slow, subtle results
Unlike some anti-aging ingredients, this peptide works gradually. You may need to use it consistently for several weeks before noticing visible improvements.
Effectiveness depends on formulation
The concentration and delivery system in the product greatly affect how well the peptide penetrates and works. Not all products are equally effective.
Best for
- Adults looking to reduce early signs of aging
- Those with sensitive skin who cannot tolerate stronger anti-aging ingredients like retinol
Use caution if
- Anyone with a known allergy to synthetic peptides (rare)
- Those expecting instant, dramatic results
Usage tips
Safety summary
Palmitoyl SH-Tripeptide-1 Amide is considered safe for cosmetic use at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types. Always patch test new products.
Research notes
Peptides like Palmitoyl Tripeptide-1 have shown promise in vitro and in small clinical studies for stimulating collagen synthesis and reducing wrinkle depth. However, large-scale, long-term human trials are limited, so evidence is considered moderate.
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.
