Cyden designs and makes intense-pulsed-light hair-removal products for use at home. The Swansea-based manufacturer was set up by four entrepreneurs in 2002, but traces its origins to 1979, when one of the founders accidentally discovered that a laser permanently removed hair from his hand. Cyden has sold in excess of 2.5m devices and exports to more than 50 countries, including China and America. The company employs more than 450 people and is led by chief executive Giles Davies.
