Glossier Super Pure Niacinamide + Zinc Serum
So lightweight you can barely feel it on your skin, this serum contains niacinamide and zinc PCA (it helps reduce the look of clogged pores). The pair of ingredients are an ideal duo for balancing oil production to keep pores clear while maintaining needed moisture. Fragrance-free, it shouldn’t cause skin irritations.
What the reviews say: “Both my teenage daughter and I use this serum. We have different concerns to address: mine being dryness and hers breakouts. We have both seen an improvement in our skin after having just used it a week.”

Peter Thomas Roth PRO Strength Niacinamide Discoloration Treatment
When your focus is on reviving skin’s radiance and chasing away discoloration, this niacinamide complex contains a bevy of brighteners. Along with niacinamide, there’s tranexamic (helps reduce the look of dark spots) and kojic acids (for brightening) to tackle discoloration, says Dr. Patel. The overwhelmingly positive reviews say that this product has helped lighten scars, acne marks, and hyperpigmentation while improving the skin’s texture.
What the reviews say: “I love this product! After only a week of using it my age spots have literally almost disappeared. My skin looks beautiful, even toned, fresh and younger.”
