When we send off make-up for testing, the lab finds an asbestos fibre in two of the samples. Brunel University’s Experimental Technique’s Centre says they need to find at least 3 fibres to confirm the asbestos fibre came from the make-up sample, despite having strict protocols to ensure their lab is not the source of the contamination. This isn’t the first test of this kind. Back in 2021, the UK government’s Office for Product Safety and Standards ordered tests of 60 low-cost eye shadows and face powders and 24 child appealing make up products on sale in the UK. In 1 child appealing product, they found 1 asbestos fibre and in two of the low-cost samples, they found five and three asbestos fibres. So are there any health implication if we are exposed to trace amounts of asbestos? The World Health Organisation recognises no safe level of exposure to asbestos. The Institute of Cancer Research’s mesothelioma immunologist Dr. Astero Klampatsa weighs up the risk. She says she would personally choose talc free make- up products. In 2023, Johnson and Johnson stopped using talc as an ingredient in its baby powder worldwide. Meanwhile, British cancer patient Hannah Fletcher sues the companies that made her favourite talc based cosmetics. Lawyers fly in to leafy Surrey from America to question her.
