Ingredient review
Palmitoyl SH-Tripeptide-3 Amide
INCI: Palmitoyl SH-Tripeptide-3 Amide
A synthetic peptide that signals skin to produce more collagen, helping soften fine lines over time with minimal irritation.
In plain English
This is a lab-made peptide (a small protein fragment) attached to a fatty acid (palmitic acid) so it can better penetrate the skin. Once absorbed, it mimics a natural signal that tells skin cells to build more collagen and elastin, which are the proteins that keep skin firm and smooth. Over weeks of regular use, it can help reduce the look of fine lines and improve skin texture. It is generally well-tolerated and unlikely to clog pores.

Quick decision guide
Easy yes for most routines
Palmitoyl SH-Tripeptide-3 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-3 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 (SH-tripeptide-3) chemically bonded to palmitic acid, a fatty acid that enhances skin penetration and stability.
How it works
After application, the palmitic acid tail helps the peptide slip through the outer skin barrier. Once inside, the peptide portion mimics a natural collagen fragment, binding to receptors on fibroblasts (collagen-producing cells) and stimulating them to produce more collagen and other extracellular matrix components. This helps reinforce skin structure and reduce the appearance of wrinkles over time.
Pros
Gentle anti-aging support
Unlike stronger actives such as retinoids, this peptide is unlikely to cause peeling, redness, or irritation, making it suitable for sensitive skin types.
Backed by targeted research
Several studies show that palmitoyl peptides can stimulate collagen synthesis in human skin cells, offering a science-based approach to wrinkle reduction.
Cons and cautions
Slow, gradual results
You won't see dramatic changes overnight. Visible improvements typically take 4 to 12 weeks of daily use, which may test your patience.
Higher cost per product
Peptide-based formulations tend to be more expensive than basic moisturizers, so you'll pay a premium for this ingredient.
Best for
- Adults looking to soften early signs of aging like fine lines and loss of firmness
- Those with sensitive skin who cannot tolerate stronger anti-aging actives like retinoids
Use caution if
- Anyone with a known allergy or sensitivity to peptides or palmitic acid derivatives
Usage tips
Safety summary
Palmitoyl SH-Tripeptide-3 Amide is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential. No significant safety concerns have been raised by regulatory bodies or dermatological reviews.
Research notes
Clinical and in-vitro studies support that palmitoyl peptides can stimulate collagen production and improve skin firmness and wrinkle depth. However, most studies are small or industry-funded, and more independent research would strengthen the evidence base.
Common label clues
- Typical concentration
- Typically used at 0.5% to 3% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in the US, EU, and many other regions. Not classified as a drug; claims must stay within cosmetic boundaries (e.g., 'improves appearance' not 'treats wrinkles').
- Common uses
- Anti-aging serums, Eye creams, Moisturizers, Neck creams
- Environmental note
- Synthesized in a lab, so it does not rely on animal or plant harvesting. Its environmental impact is primarily tied to the manufacturing process and packaging.
Good to know
- Palmitoyl SH-Tripeptide-3 Amide is a close relative of Palmitoyl Tripeptide-1, another well-studied anti-aging peptide.
- It is often listed near the middle or end of an ingredient list because effective concentrations are low.
- Peptides can be deactivated by very low pH formulas, so avoid layering with strong acid exfoliants at the same time.
