Ingredient review
Hexapeptide-67 Palmitate
INCI: Hexapeptide-67 Palmitate
A synthetic peptide designed to support collagen and reduce fine lines, generally well-tolerated but with limited independent research.
In plain English
Hexapeptide-67 Palmitate is a lab-made ingredient that combines a small protein fragment (peptide) with a fatty acid (palmitate) to help it absorb into skin. It's used in anti-aging products to signal skin cells to produce more collagen and elastin, which can make skin look firmer and smoother over time. Think of it as a gentle messenger that tells your skin to act younger.

Quick decision guide
Useful, but context matters
Hexapeptide-67 Palmitate 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 Hexapeptide-67 Palmitate.
- 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 (a short chain of amino acids) that has been chemically bonded to palmitic acid, a fatty acid, to improve its ability to penetrate the skin's outer layer.
How it works
Once applied, the palmitate tail helps the peptide slip into the upper layers of skin. The peptide then mimics natural signaling molecules, encouraging fibroblasts to produce more collagen and elastin. This can lead to a gradual improvement in skin firmness and a reduction in the appearance of fine lines and wrinkles.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive skin types.
Targets aging signs
Specifically designed to support collagen production, which can help with fine lines and loss of firmness over time.
Cons and cautions
Slow results
Visible improvements typically take weeks to months of consistent use, not overnight.
Limited independent research
Most studies are funded by manufacturers, and there are fewer peer-reviewed human trials compared to some other peptides.
Best for
- Adults looking for a gentle anti-aging ingredient
- Those with sensitive skin who want to avoid stronger actives like retinol
Use caution if
- Anyone allergic to any component of the peptide or palmitate
- Those expecting instant, dramatic results
Usage tips
Safety summary
Hexapeptide-67 Palmitate is considered safe for cosmetic use at typical concentrations. It has a low potential for skin irritation and is not known to be comedogenic. As with any ingredient, patch testing is recommended for those with very sensitive skin.
Research notes
Research on this specific peptide is limited and mostly manufacturer-sponsored. However, the mechanism of action is well understood from studies on similar palmitoyl peptides, which show they can stimulate collagen synthesis in lab and some human studies.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved as a cosmetic ingredient in the US, EU, and many other regions. Not classified as a drug.
- Common uses
- Anti-aging serums, Eye creams, Facial moisturizers
- Environmental note
- Synthetically produced, so it does not rely on animal or plant harvesting. Its environmental impact is minimal at typical use levels.
Good to know
- Peptides are often listed near the end of ingredient lists because they are effective at very low concentrations.
- Combining with antioxidants like vitamin C may enhance overall anti-aging benefits.
