REN launched their ‘Clean Bio Active Skincare’ range in 2000 after company founder Antony Buck’s wife suffered from allergic reactions to skincare products whilst she was pregnant. In partnership with Robert Calcraft, Antony developed a ‘truly desirable’ range of high quality skincare products, free from synthetic fragrance and colours, petrochemicals, propylene glycol, animal ingredients, PEGs, TEA/DEA, sulfates, silicones and parabens.
