When you're looking for something more than just feelgood, that is, when you're looking for results, this is Paris' incomparable address. The secret of famous actresses and models, the day you schedule your bespoke facial, is the day you'll start to look about 15 years younger. No joke. The highly tailored, individualized skin diagnostic they do to measure your skin's elasticity, its collagen and sebum levels, the state of its hydration and pigmentation, all set you up for treatments with their unbelievably precise facial massage techniques and beauty products to leave you feeling, and, importantly, looking like years have been sculpted off of your face. Nice plus: all produces here, made by Biologique Recherche, are perfume and fragrance-free, paraben-free, conservative-free and are nearly all 90% or more natural-product based.
