Boots shoppers are flocking to get their hands on a 'divine' perfume that's now half price. YSL Black Opium Eau de Parfum Extreme would normally cost £102 for a 50ml bottle but has dropped down to £51 as part of the Star Gifts promotion on the site. This addition to the Black Opium line was launched in 2021 with Olivier Cresp on the nose. Cresp is a legendary French perfumer who has worked on hundreds of scents including Thierry Mugler Angel , Kayali Yum Pistachio Gelato and Paco Rabanne XS .
