The devices created by this Swansea manufacturer use high-intensity pulses of light to target unwanted hair and stop growth at the root. The products scan the user’s skin tone before setting the energy level required. The company sells its SmoothSkin range in more than 30 countries, and, in 2017, opened an office in Japan — one of its fastestgrowing markets. In 2019, chief executive Giles Davies, 53, oversaw international sales of £46.8 million.
