Science
Mechanism of Action
Fullerenes exert their primary action as potent antioxidants, efficiently neutralizing free radicals due to their numerous double bonds, maintaining stability even after reaction. They also exhibit antibacterial effects against *Propionibacterium acnes* and reduce sebum production, contributing to acne alleviation. Furthermore, fullerenes support skin regeneration, enhance collagen synthesis, improve hydration, and contribute to overall skin protection by inhibiting undesirable cellular changes and melanin production.

Key findings
- 01 In a 2-month clinical trial, a 1% fullerene cream applied twice daily significantly reduced acne, pus accumulation, and sebum production without impairing skin barrier function or moisture levels.
- 02 An 8-week randomized, double-blind study on 23 Japanese women showed that a LipoFullerene cream (fullerene-C60 at 278 ppm in squalane) applied twice daily significantly boosted skin moisture and reduced wrinkle formation compared to placebo.
- 03 Studies indicate that fullerene lotion application over 2 months can decrease wrinkle depth, increase skin collagen, and enhance hydration for plumper skin.
- 04 A small 8-week study involving 10 individuals reported a 17.6% reduction in conspicuous facial pores with twice-daily fullerene cream application.

Formulation
Stability
Fullerenes are inherently stable to light, heat, and pH. While pure C60 is oil-soluble, water-soluble derivatives exist for broader formulation compatibility. For incorporation into aqueous phases, temperatures below 40°C (100°F) are recommended. Higher concentrations of certain derivatives, like fullerenol, may lead to agglomeration, potentially reducing efficacy.
Safety
Safety Profile
The EU Scientific Committee on Consumer Safety (SCCS) has expressed significant concerns regarding the safety of fullerenes in cosmetics, citing insufficient data on potential genotoxicity, impurities, potential for free oxyradical production, phototoxicity, and systemic absorption. Specifically, hydrated forms of hydroxylated fullerenes are deemed unsafe due to genotoxicity. While early research suggested low irritation, the SCCS indicates a pressing need for comprehensive data, otherwise, fullerenes may face a ban. A sensitivity test is advisable, especially for sensitive individuals, given these concerns.

Verdict
While fullerenes demonstrate promising multi-functional benefits from clinical studies, their widespread use is questionable due to significant safety concerns raised by the SCCS regarding potential genotoxicity and other unknown risks, requiring further comprehensive data.
