Niacinamide Serum 12% Plus Zinc 2%

My skin texture has improved noticeably in just two weeks of nightly use—those stubborn dark spots around my cheeks are finally starting to fade, and the 12% concentration feels potent without any stinging. I've tried other serums before, but this one actually delivers on its pore-refining promise,

My dark spots have visibly faded after a month of nightly use, and the 12% concentration feels strong yet doesn't irritate my skin. The dropper makes it easy to apply just a few drops, which is perfect because a little goes a long way.

My skin has been ridiculously oily lately, but after three weeks of this serum my T-zone finally feels balanced instead of greasy by noon. The 12% niacinamide with zinc is strong yet doesn't dry me out, and I've already noticed my pores look a bit tighter.
