This helped alot with treating my acne and hyperpigmentation. When a blemish would be forming it would be very minor and go away sooner compared to not using niacinamide.

It could be a slightly tacky on me until i figured out a way around that.

I would add a few drops, you dont need a lot, into my palm and then gently rub over my slightly damp  face and neck. Pat gently and let settle into skin a couple minutes.
