Ingredient review
Azafullerenedione Derivative
INCI: Docosyloxymethoxybenzyl Azafullerenedione
A novel, lab-made antioxidant that may help fight free radicals, but human research is very limited and it's mostly found in luxury products.
In plain English
This is a man-made molecule based on fullerenes (tiny carbon spheres). In skincare, it's added to help neutralize free radicals from pollution and UV exposure, which can damage skin cells. Think of it as a very small sponge that soaks up harmful molecules. Because it's new and expensive, you'll mostly find it in high-end anti-aging products, and we don't yet have strong proof it works better than well-studied antioxidants like vitamin C or E.

Quick decision guide
Useful, but context matters
Azafullerenedione Derivative 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 Azafullerenedione Derivative.
- 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 derivative of fullerene (C60), modified with a docosyl chain and a benzyl group to improve stability and skin penetration.
How it works
It acts as a powerful electron acceptor, meaning it can neutralize free radicals (unstable molecules that cause oxidative stress) before they damage skin cells. The docosyl chain helps it stay in the skin's outer layer longer.
Pros
Strong lab antioxidant
In test-tube studies, it neutralizes a wide range of free radicals, potentially more effectively than some traditional antioxidants.
Stable formulation
The chemical modification makes it more stable in products than plain fullerene, so it's less likely to degrade before you use it.
Cons and cautions
Lack of human evidence
Most research is in labs or on animals; there are very few published human trials showing real-world anti-aging benefits.
High cost, low value
It's expensive to produce, so products containing it are pricey. You may get similar or better results from cheaper, well-studied antioxidants.
Best for
- People interested in cutting-edge, luxury skincare
- Those with high exposure to pollution or UV who want extra antioxidant protection
Use caution if
- Budget-conscious shoppers
- Anyone with very sensitive skin (though irritation risk is low)
Usage tips
Safety summary
Generally considered safe at low concentrations used in cosmetics. No significant irritation or toxicity reported in available studies, but long-term human safety data is lacking.
Research notes
Evidence is mostly from in vitro (lab) and animal studies showing strong antioxidant capacity. Human clinical trials are scarce, so the real-world anti-aging efficacy remains unproven.
Common label clues
- Typical concentration
- Very low, typically under 0.1%
- Regulatory status
- Approved for cosmetic use in most regions including the EU and US, but not specifically reviewed by the FDA as a drug.
- Common uses
- Anti-aging serums, Luxury creams
- Environmental note
- Synthetic and produced in small quantities; no known environmental concerns at typical cosmetic usage levels.
Good to know
- Fullerenes were discovered in 1985 and won the Nobel Prize in Chemistry in 1996.
- This ingredient is not the same as 'fullerene' itself; the chemical tweaks aim to improve performance.
