This cult French skincare line is all about max results—even if a serum smells like vinegar. Its latest innovation—a 3D-printed nanofibre mask patch—was inspired by medical treatments for burn victims.

During the new Seconde Peau treatment, these patches are applied to strategically impart doses of pure hyaluronic acid, which gives skin cells marching orders to regenerate, synthesize collagen and smooth wrinkles. The patches are the cherry on top of a full dew-imparting facial, with exfoliating, masking and layers of serums and moisturizers—all applied with cool hands and cold water as per the brand’s skin-soothing principles. —Rani Sheen
