Clarins’ Blue Orchid Face Treatment Oil is a bestselling product for a reason. It’s part of the Aroma collection, which harnesses the brand’s 70 years of expertise in aromatherapy, and is the perfect all-rounder for moisture-depleted skin. How has it earned this title? A 100% plant-powered formula – blue orchid extract, hazelnut oil and rosewood and patchouli essential oils, in this case – that, once absorbed, prevents moisture loss and leaves skin feeling supple, nourished and balanced.
