Amazing product
I'm 75. No wrinkles thanks to genetics and a daily application of sunscreen. I use retinol, BHA and vitamin C. Still, my skin just wasn't where I wanted it to be. So, I shelled out the $6 for this niacinamide product and figured I could toss it if my skin didn't like it. I woke up the next morning and couldn't believe what I saw. My skin was smoother, brighter, and the muddiness in the tone was gone. I use it at night and use the C in the morning (i think they don't work well together). Absolutely a keeper, and my thanks to The Ordinary for making it so affordable.

A must have in my morning and night routine
after using this for years! It’s been amazing! I love this product! Works well and not harsh on the face! I am prone to pimples and I have a habit of popping them and using pimple patches and at night after taking them off. I put this on my face to remove pimple dark

Works With Consistency
I’ve been using The Ordinary Niacinamide for almost three years now, and it has worked really well for me. I noticed a difference in the appearance of my pores after consistently using it for about four to five months. I usually use it around 3–4 times a week rather than every day, and I’ve continued to see good results. It’s definitely one of those products I keep coming back to.

I use it for my break outs only
Not a bad product depending on your skin. it breaks me out. ( i think i am sensitive to niacinamide and have sensitive skin). Now i use it if i get pimples i appyl it locally on top and it helps them heal faster. Will not buy again tho
