  • Opinion
Size: 1 Fl Oz (Pack of 1)
I've been using the Good Molecules Niacinamide Serum, and I love how lightweight it feels on my skin. It helps control my oil throughout the day and has really improved the look of my pores and dark spots. My skin looks smoother and more balanced without feeling dry. He estado usando el suero de niacinamida de Good Molecules y me encanta lo ligero que se siente en mi piel. Me ayuda a controlar la grasa durante el día y ha mejorado mucho el aspecto de mis poros y manchas. Mi piel se ve más suave y equilibrada, sin sentirse reseca. ... show more

  • HOLY GRAIL STATUS ✨
Size: 1 Fl Oz (Pack of 1)
This serum seriously deserves the hype. I’ve been using the Good Molecules Niacinamide Serum every morning and night for a few weeks and the difference in my skin is actually wild. My acne has chilled out so much, my skin tone looks way more even, and my pores aren’t screaming at me anymore. It’s super lightweight, not sticky at all, and layers perfectly under my moisturizer and SPF. I love that it’s 10% niacinamide without irritating my sensitive skin (literally a miracle). Plus, it gives my skin this soft, hydrated glow that makes me feel like that girl even on no-makeup days. Also, random but worth mentioning — the packaging is actually super sturdy and feels high quality. It’s a glass bottle that doesn’t feel cheap or flimsy, and the dropper works perfectly every time. If you’re struggling with breakouts, texture, or dullness, add to cart immediately. It’s affordable, it works, and it’s giving main character skin. 💁♀️💕 ... show more

  • Highly recommend
Size: 1 Fl Oz (Pack of 1)
It truly works! I have sensitive skin, and I've never had any issues with it. There's no fragrance, and it goes on clean without leaving any residue. I use it in the morning and evening before applying my moisturizer. This is my favorite brand, and I highly recommend it for all skin types.

  • Permanent Staple
Size: 1 Fl Oz (Pack of 1)
I'm on my third bottle and it has a permanent home in my morning and night skincare routine. It definitely has smoothed out some of my texture and shrunk some pores but the thing I didn't expect is how much it calmed redness in my face! You'll have to pry it out of my cold dead hands!

  • Good for Sunburn
Size: 2.53 Fl Oz (Pack of 1)
Purchased after a gnarly sunburn, had the redness gone in a day or two, and no peeling at all. Going to keep using daily, face looks and feels great.

  • great product!
Size: 1 Fl Oz (Pack of 1)
I have been using this with a few other products and have noticed a great improvement in my skin texture. This goes on very smoothly and leaves your skin feeling a bit tacky, but it is mean to go under a moisturizer. I use it in the mornings and it is very cooling. It is not oily at all, and it has no scent which is a big plus to me ... show more
