Pore Minimizing 21 Serum

A short formula at high strength: niacinamide at 20% with zinc PCA at 1%, plus willow bark water for the BHA it naturally carries. The combination goes at shine, blackheads and the size pores appear, and there is little else in the bottle beyond sodium hyaluronate, allantoin and glycerin. TIAM advises a patch test given the niacinamide level. Well suited to oily or congested skin.
