Augustinus Bader built its reputation on £300 creams, cutting-edge science, and a carefully curated luxury aura. Now it’s launched Dua by AB Science with Dua Lipa – a cheaper, separate line powered by a new TFC5 complex and sold on its own website. Is this smart brand architecture or a move that quietly undermines the original Bader promise, confuses loyal clients, and devalues high-priced collabs like Victoria Beckham Beauty?
