Syke review for 5% Niacinamide Serum

this is the first serum that i have tried and i already finished 2 bottles of this product. it surprised me that it perfoms so well on my skin knowing it’s price. it’s the best serum if you want to start using niacinamide serum because it only has 5% niacinamide. i also love the packaging of this one, it has a stopper that’s work so well and i didn’t waste any single drop of product, even if sometimes i accidentally leave my serum open.
