Would you put Teflon on your face? Probably not. That’s one of the reasons we think you’ll find our new report so troubling. Some anti-aging creams contain polytetrafluoroethylene (PTFE), a chemical used to create smooth finish on cosmetics and non-stick surfaces of some pots and pans. While PTFE does not present any health hazards on its own, it may be contaminated with perfluorooctanoic acid (PFOA), a toxic chemical linked to cancer, endocrine disruption and reproductive harm.
