COSRX Niacinamide 15% Face Serum 0.67 fl.oz/20 ml

Good

I just started using this for a little over a week, so I can’t tell any difference yet other than it makes my skin very oily. I bought it because it says it helps reduce pores & sebum, but in my case I have increased sebum when using it. I don’t if it’s part of the process & just continue using it or stop using it because it’s not working on my skin.

No me agrado

It doesn’t irritate my very sensitive skin it’s smooths and makes it shiny and has that Korean glass thing going for it

New to this product that was recommended by a friend who is in to skin care and does a lot of research on ingredients. First thing that I noticed was that a small amount smoothed on easily without the stinging sensation or scent of other similar products that I've used. Skin felt clean and fresh. Absorbed into skin without feeling tacky. Hoping to see results in a few weeks.
