Ingredient review
Hexapeptide-62
INCI: Hexapeptide-62
Hexapeptide-62 is a synthetic peptide that may help soften expression lines by temporarily relaxing facial muscles, similar to other peptide ingredients.
In plain English
Hexapeptide-62 is a short chain of amino acids (the building blocks of proteins) made in a lab. In skincare, it's used to target fine lines and wrinkles, especially those caused by repeated facial expressions. Think of it as a gentler, topical alternative to injectable treatments—it works by signaling skin cells to produce more collagen and by slightly relaxing muscle contractions, which can smooth out lines over time. It's generally well-tolerated and non-irritating for most skin types.

Quick decision guide
Useful, but context matters
Hexapeptide-62 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-62.
- 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
Hexapeptide-62 is a synthetic peptide consisting of six amino acids linked together. It belongs to a class of peptides known as 'signal peptides' or 'neurotransmitter-inhibiting peptides' because they can interfere with the signals that cause facial muscles to contract.
How it works
Hexapeptide-62 is believed to work by mimicking a protein fragment that inhibits the release of neurotransmitters at the neuromuscular junction. This reduces the intensity of muscle contractions under the skin, which in turn softens the appearance of expression lines like crow's feet and forehead furrows. Additionally, it may stimulate collagen production, helping to improve skin firmness and elasticity over time.
Pros
Targets expression lines
Hexapeptide-62 works by relaxing facial muscles, which can help soften dynamic wrinkles like crow's feet and frown lines without needles.
Low irritation potential
As a synthetic peptide, it is generally non-irritating and suitable for sensitive skin types, making it a gentle anti-aging option.
Cons and cautions
Subtle results
The effects are mild and gradual; you'll need to use the product consistently for several weeks to notice any visible improvement.
Variable effectiveness
Not everyone responds the same way, and results can depend heavily on the formulation and concentration used in the product.
Best for
- Adults looking to soften early signs of aging, especially expression lines
- Those seeking a non-invasive, topical alternative to injectable treatments
Use caution if
- Individuals with known allergies to peptides or any ingredient in the formulation
- Those expecting immediate or dramatic results similar to injectables
Usage tips
Safety summary
Hexapeptide-62 is considered safe for topical use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for most skin types. However, as with any ingredient, patch testing is recommended for those with sensitive skin or allergies.
Research notes
Research on Hexapeptide-62 specifically is limited, but it belongs to a well-studied class of anti-aging peptides. Studies on similar peptides (e.g., Acetyl Hexapeptide-8) show they can reduce wrinkle depth and improve skin texture with consistent use. More independent, peer-reviewed studies on Hexapeptide-62 are needed to confirm its efficacy.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Hexapeptide-62 is considered a cosmetic ingredient and is not regulated as a drug. It is not approved for medical use and should not be marketed as a treatment for medical conditions.
- Common uses
- Anti-aging serums, Eye creams, Moisturizers
- Environmental note
- As a synthetic peptide, Hexapeptide-62 is produced through chemical synthesis, which has a lower environmental impact compared to animal-derived ingredients, but its biodegradability is not well-documented.
Good to know
- Hexapeptide-62 is often compared to Argireline (Acetyl Hexapeptide-8) but may have a slightly different mechanism or potency.
- It is commonly found in peptide complexes alongside other anti-aging ingredients like niacinamide or hyaluronic acid.
