Tampered with Product...
This package feels like someone tampered with the product. The bottle had crusted over like it has been used. The consistency was way too watery. I have used this product for years and it seemed as if someone returned it and put another in product in the bottle. It didn't feel or look like the product that ir should be.

The Good Molecules Niacinamide serum is so absorbing and soothing and made my pores dissappear.

I feel like it definitely worth trying, I can tell my pores have looked smaller. I didn’t like the feeling of using it on my whole face but using in my tee zone and area next to my nose has made me enjoy the product more! Will definitely continue to use.

Recommend for sensitive skin
I typically have very sensitive skin and react/break out to anything I put on my face. This leaves my face feeling hydrated using it twice daily. I have not combined with any other serums yet. There is no noticeable scent after it dries.

Soooo Good Molecules serum!!! Yes please.
First time using this product and I love the way the ingredients calm and smooth my irritated skin. For me there is no detectable scent and it doesn’t feel sticky either. Would love to dive into the bottle, maybe we need this with a spray option lol.

I’ve been using this niacinamide serum for a while now, and I’m really happy with it. It feels lightweight, absorbs quickly, and layers well with the rest of my skincare routine. The bottle is a generous size for the price, so it lasts a long time and feels like a great value. My skin looks smoother and more balanced since I started using it. I would definitely repurchase it.

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.

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!
