Made with just ten ingredients, the Ultra Pure 5.0% Niacinamide Oil-Minimising High-Potency Serum by Kiehl's is a concentrated formula that visibly minimises excess oils and discolouration.

Powered by 5% niacinamide, the serum brightens the look of lacklustre skin, while reducing the appearance of pores and textural irregularities. It helps to visibly unify the skin tone, promoting a smoother, more radiant-looking complexion over time with less unwanted shine. It offers optimal efficacy, as the serum absorbs quickly and preps the skin perfectly for subsequent skincare steps.
