Ingredient review
Nicotinoyl Hexapeptide-44
INCI: Nicotinoyl Hexapeptide-44
A lab-made peptide that may help firm skin and soften lines, but human studies are still limited.
In plain English
This ingredient is a small protein fragment (peptide) that has been chemically linked to a form of vitamin B3 (niacinamide). In skincare, it is added to products aiming to make skin look firmer and reduce the appearance of fine wrinkles. Think of it as a signal molecule that tells skin cells to behave more youthfully, though the research on this specific version is not yet as strong as for some other peptides.

Quick decision guide
Useful, but context matters
Nicotinoyl Hexapeptide-44 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 Nicotinoyl Hexapeptide-44.
- 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
Nicotinoyl Hexapeptide-44 is a synthetic peptide—a short chain of amino acids—that has been modified with a nicotinoyl group (related to niacinamide). It is produced in a lab and used in cosmetic formulations for its potential anti-aging benefits.
How it works
Peptides like this one are thought to work by mimicking natural signaling molecules in the skin. When applied topically, they may encourage skin cells to produce more collagen and other structural proteins, which can help improve firmness and reduce the depth of wrinkles. The nicotinoyl part may also provide antioxidant support, though the exact mechanism is still being studied.
Pros
Gentle on skin
Nicotinoyl Hexapeptide-44 has a low irritation and comedogenic risk, making it suitable for sensitive or acne-prone skin types.
Targets aging signs
It is specifically formulated to support collagen production, which can help improve skin firmness and soften the look of fine lines over time.
Cons and cautions
Limited evidence
Unlike some well-studied peptides, Nicotinoyl Hexapeptide-44 has fewer published human trials, so its effectiveness is less certain.
Slow results
Peptides generally require consistent use over several months to show visible improvements, which may not meet everyone's expectations.
Best for
- Anyone looking for a gentle anti-aging ingredient
- People with sensitive skin who want to avoid stronger actives like retinol
Use caution if
- Those expecting fast, dramatic results
- Individuals allergic to any peptide or niacinamide derivative
Usage tips
Safety summary
Nicotinoyl Hexapeptide-44 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in available literature.
Research notes
Research on Nicotinoyl Hexapeptide-44 is still emerging. While peptide-based anti-aging ingredients are well-supported in general, specific clinical studies for this compound are limited. Most evidence comes from in vitro studies and ingredient manufacturer data.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a skin conditioning agent. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- As a synthetic peptide, its production has a lower environmental footprint compared to some animal-derived ingredients, but specific sustainability data is not publicly available.
Good to know
- This ingredient is often found in serums and eye creams targeting aging concerns.
- It can be combined with other peptides or antioxidants like vitamin C for a synergistic effect.
