I have oily skin and this serum has been a game changer. It reduces shine immediately and my skin looks matte all day. It doesn't dry out my skin either. I'm on my third bottle!
This niacinamide serum has helped with my pores and redness. It absorbs well and doesn't leave any sticky feeling. I didn't notice a huge difference in oil control, but my skin looks clearer.
After using this serum for a month, my skin is smoother and less oily. It really keeps my complexion balanced. I use it in the morning before moisturizer. Worth every cent.
It's a decent serum, but I've used other niacinamide serums that worked better. It does reduce oil a bit, but it also broke me out at first. My skin has adjusted now. Not sure if I'll repurchase.
I've struggled with oily skin my whole life, and this serum is the first thing that has really helped. It keeps my face shine-free for hours. I also love that it has only 10 ingredients – no unnecessary fillers. Highly recommend!
This serum is potent – I had to start with every other day to let my skin adjust. Now I use it daily and it's fine. It does help with oil and makes my skin feel smoother. Just be careful if you have sensitive skin.
I've only been using this for two weeks and my skin looks so much better. My oily T-zone is less oily, and my pores are smaller. It's a bit pricey, but a little goes a long way. I'll definitely buy again.
I have sensitive skin and this serum gave me a rash. I've used other niacinamide products without issues, but this one was too strong. Maybe it's the concentration. Unfortunately, I had to stop using it.
