The UK is in the grip of a scorching heatwave and the Met Office has issued unprecedented red warnings of "extreme heat" as temperatures are forecast to rise above 40C for the first time.
Application of sun cream is vital for anyone venturing outdoors in the hot weather. And experts are warning that make-up and other beauty products containing SPF cannot be relied upon to offer protection from the sun's harmful ultraviolet rays.
Bruce Green, a Chartered Chemist and founder of SOS Serum Skincare, says people should ensure they are using proper sun cream. He told The Mirror: "Whilst double-duty products may make steps shorter and seem more efficient, you cannot always rely on your daily moisturisers or make-up products such as a foundation to give you adequate protection."
