Ingredient review
Hexapeptide-62 Dimer
INCI: Hexapeptide-62 Dimer
A synthetic peptide that may help smooth fine lines and improve skin firmness, but human data is still limited.
In plain English
Hexapeptide-62 Dimer is a lab-made chain of amino acids (the building blocks of proteins) designed to signal skin cells to behave more youthfully. In skincare, it's used to encourage firmer, smoother-looking skin, similar to how other anti-aging peptides work. Because it's a relatively new ingredient, most evidence comes from lab studies rather than large human trials.

Quick decision guide
Useful, but context matters
Hexapeptide-62 Dimer 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 Dimer.
- 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
A synthetic peptide consisting of six amino acids linked together in a dimer (two identical units) structure, engineered to mimic natural signaling molecules in the skin.
How it works
When applied topically, the peptide is thought to bind to skin cell receptors and stimulate collagen production or inhibit muscle contractions that cause expression lines, leading to a temporary smoothing effect.
Pros
Targeted anti-aging support
Hexapeptide-62 Dimer is designed to specifically address signs of aging like fine lines and loss of firmness, making it a focused ingredient for mature skin routines.
Low irritation potential
As a synthetic peptide, it is generally non-irritating and suitable for sensitive skin types, unlike some stronger active ingredients such as retinol or acids.
Cons and cautions
Limited human research
Most evidence for Hexapeptide-62 Dimer comes from in vitro (lab) studies; large-scale human trials are lacking, so its real-world efficacy is not fully proven.
Higher cost
Peptide ingredients are expensive to produce, so products containing Hexapeptide-62 Dimer tend to be pricier than basic moisturizers with similar texture benefits.
Best for
- Adults looking for anti-aging support
- Those with sensitive skin seeking gentle peptide options
Use caution if
- Anyone allergic to synthetic peptides (rare)
- Those expecting immediate dramatic results
Usage tips
Safety summary
Hexapeptide-62 Dimer is considered safe for topical cosmetic use at typical concentrations. No significant irritation or sensitization has been reported in available studies, but long-term safety data is limited due to its novelty.
Research notes
Preliminary lab studies suggest Hexapeptide-62 Dimer may stimulate collagen synthesis and reduce expression lines, but peer-reviewed human clinical trials are sparse. More research is needed to confirm its efficacy and optimal formulation.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU, US, and other major markets; not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- Synthetic peptides are produced via chemical synthesis, which has a lower environmental footprint than animal-derived ingredients but requires energy-intensive processes.
Good to know
- Peptides work best when combined with other supportive ingredients like antioxidants (vitamin C, vitamin E) and moisturizers (hyaluronic acid, glycerin).
- The 'dimer' structure may enhance stability and skin penetration compared to single-chain peptides.
