The Drying Concentrate is an SOS treatment that purifies and reduces localised imperfections from the 1st night while limiting the appearance of residual marks. At the heart of the formula, the right dose of Pure Salicylic Acid, recommended by dermatologists for its purifying properties, is combined with rebalancing Zinc Gluconate and antibacterial Calamine Powder to rapidly correct all types of imperfections (spots, blackheads, shine, residual marks). Formulated with 98% natural-origin ingredients, its texture is composed of two distinct phases (powder and liquid) to maintain all the potential of the active compounds and maximise the synergetic effectiveness of each of them.
