Naturally occurring silicate mineral that is typically the main ingredient in face powders and is also used as an absorbent in skincare products. Extensive research indicates there’s no increased risk of lung cancer when using talc-based products or for those involved in the manufacture of talc products.  Although there’s epidemiological evidence that frequent use of pure talc over the female genital area may increase the risk of ovarian cancer. [2,3] However, a study reviewed in Regulatory Toxicology and Pharmacology stated that “Talc is not genotoxic, it is not carcinogenic when injected into ovaries of rats.… There’s no credible evidence of a cancer risk from inhalation of cosmetic talc by humans.”
