THE BETTER B NIACINAMIDE SERUM from Dr. Barbara Sturm is the perfect skin perfector that specifically targets pores, reducing and refining their appearance for a radiant complexion. The serum contains a powerful complex of ingredients including pure vitamin B3 and ectoine, an amino acid that helps protect against environmental hyperpigmentation and premature skin aging. The formulation also includes marine exopolysaccharides (plankton) that help strengthen the skin barrier, increase hydration, and support the skin's natural repair processes for a smoother, softer, and more refined skin texture, as well as Panthenol (Provitamin B5), an ultra-moisturizing ingredient that also has soothing properties. THE BETTER B NIACINAMIDE SERUM is ideal for rough, uneven complexions with visibly enlarged or sunken pores and for classic combination skin types. With regular use, it will leave the skin more even, radiant, and noticeably refined. 30 ml
