Talc is generally safe when applied externally to the skin and helps keep skin dry and comfortable. However, inhaling fine talc dust can irritate the lungs, so care is needed to avoid breathing in large amounts. A key health concern is the possible contamination of talc with asbestos, a carcinogen. Cosmetic talc products today undergo strict testing to ensure they are asbestos-free. To minimize risks, users should apply talc carefully, avoid inhalation, and choose trusted brands that confirm asbestos-free status.
