No Effects Found
Authors not listed · 2025
Human skin cells showed no genetic damage when exposed to 5G radiation at ten times regulatory limits.
Plain English Summary
Summary written for general audiences
Researchers exposed human skin cells (fibroblasts and keratinocytes) to 5G electromagnetic fields at levels up to ten times higher than regulatory limits for 2 and 48 hours. The study found no significant changes in gene expression or DNA methylation patterns compared to unexposed control cells, suggesting 5G radiation does not damage human skin cells at these exposure levels.

}Quick Questions About This Study
No, 5G frequencies only penetrate about 1 millimeter or less into skin tissue. This shallow penetration depth is why researchers focused specifically on skin cells like fibroblasts and keratinocytes, which would receive the highest exposure levels from 5G signals.
The study exposed skin cells to electromagnetic fields up to ten times higher than current regulatory limits. This extreme exposure level was intentionally chosen to test for potential effects under conditions far exceeding real-world 5G exposure from towers or devices.
The study found no significant changes in gene expression or DNA methylation patterns in exposed skin cells. Any differences observed were small and no greater than what would be expected by random chance, indicating no measurable cellular damage occurred.
Researchers exposed the skin cells for both 2 hours and 48 hours to test for both acute and longer-term effects. Neither exposure duration produced detectable changes in cellular function or genetic activity compared to unexposed control cells.
Yes, the study used a fully blinded design with sham-exposed cells as negative controls and UV-exposed cells as positive controls. This rigorous methodology helps ensure that any observed effects were truly due to 5G exposure rather than experimental artifacts.
