I’ve been pleasantly surprised with the Vita B3 Source (and their new packaging) that was gifted to me by Korean skincare brand Tia’m. With 10% Niacinamide and 2% Arbutin, this serum effectively takes the place of two different serums I had previously tried from another popular brand with the same concentrations. #sensitiveskin #acneskincare #niacinamide #hyperpigmentation
