Q. Who should use niacinamide?
All skin type, especially Oily and Acne-prone skin.
Q. Who should use/not use niacinamide?
It’s good for all skin types. Although we recommend The Niacinamide 15 Serum for oily and acne skin. However, it can be used for dry skin.
Q. Can you use vitamin C and niacinamide together?
No, we recommend using Niacinamide and vitamin C separately because both ingredients are high-concentrated and it can be caused too much irritation to skin.
Q. What can I use niacinamide with?
Anything goes with niacinamide, but it is best when paired with BHA or Propolis.
Q. Can I use salicylic acid and niacinamide together?
Yes, when Niacinamide combines BHA which is good treatment for pores and sebum, it is more helpful in unclogging pores and reducing excess sebum.

I revived this from Influenster and Corsx and i have been using for about 2 weeks and i love it. It has no strong fragrance and is very light weight on the skin and feels so good after it’s dried down
I received this serum free from Influenster and COSRX. So upon first application, I noticed that this is like the softest serum I’ve ever used. It dried and you couldn’t feel it. I didn’t notice a smell either. I really like this one.
Unfortunately after reading reviews I did not feel comfortable putting this product on my face due to having sensitive skin and Rosacea. And I just got my face back to normal after having a really bad breakout. Maybe in a couple months after my skin has had some more time to heal I will give it a try! The packing is super cute tho.
I really like this niacinamide serum. It comes in a nice luxurious bottle with dropper. It has no major smell, and goes on really smooth. It works great for daily oil control and minimizing pores! I followed it with a sunscreen too. Highly recommend!
I love Cosrx, so I was super excited to learn that I’d be receiving this product free to review from them and Influenster! So far, I absolutely love it. It blends into my skin easily, leaves no sticky or flaky residue, and I am already able to see a noticeable change in how my skin feels after just 2 weeks. I’m having few pimples pop up randomly, even on my period. My skin feels smoother, my pores are less clogged. I will update this review in a couple months after I’ve run out of the serum!
