it was $17 on amazon. I started using it thursday 8/6/2020 in my AM routine. i haven't broken out from it. i like that it absorbs easily and that the bottle is BIG. you only need 2-4 drops for your face so i see this lasting a long time. i like that it's fungal acne safe, too. however, I haven't used it long enough to see results.

I previously used Niacinimide and Alpha Arbutin from The Ordinary. The reason why I changed to Tiam B3 is because of its light formula and no pilling compared to The Ordinary Niacinimide. In addition, I do not need to buy another product for Alpha Arbutin because Tiam B3 already included Alpha Arbutin in its formula. One bottle can last for quite some time as I just need to use like 2 drops to cover my whole face. It absorbs easily and does not feel heavy or oily. I used it while having acne breakout and it does not trigger more acne in my face. The price is also reasonable. Definitely will repurchase this.

I've been using Vita B3 for about 2 months now and I really see the difference! My skin is brighter, clearer and my post-pregnancy hyperpigmentation is much less noticable, to the point that I think I am the only one who can still notice it. It took me about a week of daily use to be able to see the first effects, or rather say nightly use. It only takes a few drops to cover entire face and it soaks well into the skin without piling. I still have half bottle left and will be happy to repurchase it.
