Perfect for those with oily skin, The Ordinary Niacinamide 10% + Zinc 1% is a concentrated serum that reduces the appearance of blemishes & pores. Enriched with niacinamide (vitamin B3), The Ordinary gel-like serum gives skin a more visibly even appearance by minimising congestion. Also known as vitamin B3, the do-it-all ingredient strengthens the skin's immunity & locks in moisture, so skin is nourished & hydrated. The Ordinary Niacinamide 10% + Zinc 1%'s gentle serum also regulates sebum production. This shrinks pores & limits the production of bacteria that cause blemishes, so skin is left looking smoother & less oily. The high 1% concentration of zinc salt repairs damaged skin & encourages the creation of collagen, a natural protein that keeps skin looking supple, plump & youthful-looking. Why We Love It Despite its thick liquid texture, the serum absorbs into the skin almost immediately. This makes it perfect for those with an oily skin type, as it doesn't leave an oily residue or create any additional shine while smoothing enlarged pores & controlling breakouts.
