Bought with my own money, The Ordinary Niacinamide 10%

I've lost count of how many bottles I've used. It's The Ordinary Niacinamide.

It seems like a real must-have for oily skin. I think it might be a bit drying for dry skin.

For oily skin, it almost completely stops sebum production, refines skin texture, and brightens the skin.

I think I've been using this for over a year. My neck and face used to be the same tone, but now my face is much brighter.

And since the sebum stopped coming out, the breakouts that used to appear so often finally stopped.

It is such a good product.
