Product details:Specifically formulated to target problem pores, reducing and refining their appearance for a radiant complexion, Dr. Barbara Sturm's The Better B Niacinamide Serum will help you on your way to a clear canvas-like complexion.What makes it 'better' than other niacinamide serums? It's crafted with high quality niacinamide (pharmaceutical, purified standard) at an ideal concentration of 5% which means it ultra-effective whilst being non-irritating to your skin. The hero ingredient is in good company too; ectoin, an amino acid, helps to protect against environmental hyperpigmentation and premature skin aging while marine exopolysaccharides (plankton) works to strengthen your skin barrier, boost hydration, and support the skin's natural restorative processes - ultimately promoting a smoother, softer and refined skin texture. Finally, ultra-hydrating panthenol (provitamin B5) lends the blend its soothing properties so you can enjoy all of the balancing benefits of niacinamide without running the risk of irritation.
