Photo Review of The Ordinary Niacinamide 10% + Zinc 1%

Been trying this serum out (twice daily) for the past few months. Little goes a long way - my bottle still looks pretty full. Pores are not as noticeable and my T-zone isn’t as greasy. I have sensitive skin but haven't had any issues with irritation or dryness despite the high concentration of Niacinamide.
