Ingredient review
Hexapeptide-47
INCI: Hexapeptide-47
Hexapeptide-47 is a synthetic peptide that may help calm skin and strengthen the moisture barrier, but research is still early.
In plain English
Hexapeptide-47 is a short chain of amino acids (a peptide) made in a lab. In skincare, it's added to help soothe irritated skin and support the skin's natural barrier. Think of it as a gentle signal that tells skin cells to behave more calmly and hold onto moisture better. Because it's a peptide, it's generally well-tolerated, but it's not a miracle cure — results are subtle and take time.

Quick decision guide
Useful, but context matters
Hexapeptide-47 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-47.
- 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
Hexapeptide-47 is a synthetic peptide composed of six amino acids. It is designed to mimic natural signaling molecules in the skin that help regulate inflammation and barrier function.
How it works
Hexapeptide-47 works by interacting with skin cells to reduce the release of pro-inflammatory signals. This helps calm redness and irritation. It also supports the production of proteins that strengthen the skin barrier, which can improve moisture retention and resilience over time.
Pros
Gentle on skin
Hexapeptide-47 has a low irritation and comedogenic risk, making it suitable for sensitive skin types.
Barrier support
It may help strengthen the skin's natural barrier, which can improve moisture retention and reduce sensitivity over time.
Cons and cautions
Limited evidence
Most research on Hexapeptide-47 is from lab studies or small trials; large-scale human studies are lacking.
Subtle effects
Benefits are mild and gradual, so it may not satisfy those seeking quick or dramatic improvements.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, supportive ingredient to strengthen their moisture barrier
Use caution if
- Anyone allergic to any component of the peptide (rare)
- Those expecting fast or dramatic anti-aging results
Usage tips
Safety summary
Hexapeptide-47 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. No significant safety concerns have been reported in available literature.
Research notes
Research on Hexapeptide-47 is emerging. Preliminary studies suggest it may reduce inflammatory markers and support barrier proteins, but most evidence comes from in vitro or small-scale studies. More robust clinical trials are needed to confirm efficacy.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets. Not classified as a drug ingredient.
- Common uses
- Serums, Moisturizers, Eye creams
- Environmental note
- Synthetic peptides are produced in labs, which reduces environmental impact compared to animal-derived ingredients, but manufacturing energy use should be considered.
Good to know
- Peptides like Hexapeptide-47 are often listed near the middle or end of ingredient lists because they are used at low concentrations.
- It is stable in most formulations but avoid combining with very low pH products (like strong AHAs) in the same step.
