Fullerene nanoparticles show strong antioxidant benefits that make them attractive for skincare products, but the research reveals a significant concern: these same particles can potentially damage or kill skin cells at certain concentrations. The authors emphasize that while fullerenes are promising, their safety profile in cosmetics needs more rigorous testing before we can confidently say they're risk-free for regular use.

This was a review study, meaning the authors analyzed and summarized findings from multiple existing research papers on fullerene nanoparticles in skincare rather than conducting their own experiment. They assessed both the benefits and toxicity concerns documented in the scientific literature.
