Meh
I purchased this as an alternative to the face shop formula when I ran out because it was only $5.99. This serum feels very heavy and just sits on my skin. I don't feel like it penetrates well and I haven't seen any improvement in my skin since using it instead of the fave shop formula.

Perfect for my combo skin!
I have sensitive, combination skin & and am acne prone as well.. yikes. I notice a difference when I’m consistently using niacinamide vs when I’m not. I have tried both Good Molecules & The Ordinary & This is my 3rd repurchase of the Good Molecules one due to its price point + quality. I notice the same results between brands but gravitate towards this one more

Legit
I am very impressed with this product! I wasn’t sure about it due to the price point but the other reviews had me intrigued so I gave it a shot. This makes my skin smooth and is fading the signs of lines on my forehead. I am very happy I tried this, I love it!

Caused breakouts
Made me break out so bad. I’ve gone through so many bottles of the naturium niacinamide serum and decided to try something more affordable. Bad idea. Do not recommend!

This stuff works
I’ll definitely say this works I was iffy on it because of the reviews but safe to say it works i have gotten a pimple and it has been taken care of them after putting the serum on for 2 days and the pimple ends up slowly going away so I’ll say this product works

Excellent
I've been using Inkey List for years. But since using the Good molecules for a few months now, the little bumps on my face have disappeared.

Great inexpensive and pot
Great inexpensive and potent niacinamide. I mix it into toner to help it spread easily. Will make your pores look smaller. Love it.
