Ingredient review
Zinc Hexapeptide-11
INCI: Zinc Hexapeptide-11
A synthetic peptide that may help firm skin and soften fine lines, with low irritation risk but limited independent research.
In plain English
Zinc Hexapeptide-11 is a man-made protein fragment (a peptide) attached to zinc. In skincare, it's used to signal skin cells to produce more collagen and elastin, which are the building blocks that keep skin plump and firm. Think of it as a tiny messenger that tells your skin to act younger. It's often found in anti-aging products, especially around the eyes, because it's gentle and targets fine lines without causing irritation.

Quick decision guide
Useful, but context matters
Zinc Hexapeptide-11 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 Zinc Hexapeptide-11.
- 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 is chemically bonded to zinc. Peptides are building blocks of proteins like collagen, and adding zinc can enhance their stability and skin benefits.
How it works
When applied topically, Zinc Hexapeptide-11 is thought to mimic natural peptide signals in the skin, encouraging fibroblasts (the cells that make collagen) to increase production of collagen and elastin. The zinc component may also provide antioxidant protection and support skin repair processes.
Pros
Gentle anti-aging support
Zinc Hexapeptide-11 is very well-tolerated, making it a good option for sensitive skin or the delicate eye area where stronger ingredients might cause irritation.
Low irritation and comedogenic risk
It rarely causes redness or breakouts, so it can be used daily without disrupting the skin barrier.
Cons and cautions
Subtle, gradual results
Unlike retinoids or acids, this peptide works slowly. You may need to use it for 8–12 weeks before noticing a visible difference in fine lines.
Limited independent research
Most studies are funded by ingredient suppliers. There are few peer-reviewed, independent trials confirming its efficacy compared to other peptides.
Best for
- Anyone looking for a gentle anti-aging ingredient to soften fine lines
- People with sensitive skin who want to avoid stronger actives like retinol
Use caution if
- Those seeking dramatic, fast results (peptides work gradually)
- Individuals allergic to zinc or peptide-based ingredients (rare)
Usage tips
Safety summary
Zinc Hexapeptide-11 is considered safe for topical use in cosmetics at typical concentrations. It has a low irritation and comedogenic profile, making it suitable for most skin types, including sensitive skin. Allergic reactions are rare.
Research notes
Evidence for Zinc Hexapeptide-11 comes primarily from manufacturer-sponsored studies showing improvements in skin firmness and wrinkle depth over 8–12 weeks. Independent peer-reviewed research is limited, but the ingredient's mechanism is supported by broader peptide science.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety regulations.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- Synthetic peptides are produced in laboratories, which reduces the need for natural resource extraction, but their manufacturing process may involve chemical solvents.
Good to know
- Peptides are most effective when used consistently as part of a daily routine.
- Zinc Hexapeptide-11 is often combined with other peptides in anti-aging formulas for a synergistic effect.
