In Singapore, TPO is not banned. The Health Sciences Authority (HSA) permits it for professional use at limited concentrations, with\u00a0labelling requirements such as\u00a0\u201cavoid skin contact\u201d.\u00a0<\/span><\/p>\n Unlike medicines, cosmetics in Singapore are not individually tested or approved before sale. Companies must ensure their products meet safety and labelling requirements, while HSA monitors the market through checks and investigations.<\/span><\/p>\n The\u00a0Ministry of Manpower, the National Environment Agency\u00a0and HSA issued a joint circular\u00a0in 2024 advising salons on ventilation, safe handling of products and protecting workers and customers from exposure to harmful chemicals. TPO was not singled out, but the advisory reflected awareness that nail services involve substances that deserve careful use.<\/span><\/p>\n Does Singapore need to do more?\u00a0<\/span><\/p>\n Gel manicures are hugely popular in Singapore:\u00a0according to a news report last year,\u00a0there were around 537 accredited nail and beauty salons as of March 2024, with many more working towards accreditation. During the pandemic, home-based nail services flourished, expanding access even further.\u00a0<\/span><\/p>\n Few of us would think to ask what brand of gel polish a salon uses, let alone check the ingredients label for technical names like TPO. It would be reasonable for people to assume that what is available at the salon has already been vetted.\u00a0And with the rise of e-commerce, gel polish kits, including those with TPO, are readily available online, shipped in from anywhere.\u00a0A product banned in Europe can still be sold legally in Singapore or other markets.<\/span><\/p>\n<\/div>\n
