I love this!
This product helped me achieve my skin goals. I'm so impressed with what it has done for my skin. My pores are actually smaller, I haven't had any breakouts, and my skin just looks so radiant. It also controls my oil. I use it every morning.

Please spot check!!!
I got a huge rash all over my face and neck from this product. From what I’ve read this can happen from niacinamide of a too high concentration. It’s weird because I use niacinamide 5% from another brand. As such, I can’t really suggest this product. Definitely spot test and wait a few days if you try this.

Game changer for oily skin!
This product has been a huge game changer for me, I have super oily skin specialy in the t-zone areas, I apply this product once daily in the mornings before applyong my daytime moisturizer. This product is sold out often in stores, so ordering online may be best.

Oily acne prone skin’s must have
Non sticky not heavy truly focused on it’s purpose kinda serum. I have sensitive oily acne prone skin and this is the ONLY niacinamide serum that hasn’t given my any trouble. Already seeing great results in just a week of use in reduced oil production, redness. I highly recommend!

Used daily against hyperpigmentation
I’ve used this product for multiple months both morning and night and now have my mom using it to. Overtime, this helps with keeping hyperpigmentation at bay. The formula is a nice consistency that is absorbed well, and can be easily layered with either a vitamin C serum or retinol.

Not good for sensitive skin :(
My sensitive skin was very irritated unfortunately, my face was very blotchy and irritated. Do not recommend it for sensitive skin.

Maybe I haven’t been using this long enough because it’s only been about three weeks, but I haven’t noticed much of a difference in my skin. I’ve used other niacinamides in the past and love it. I will use it for longer to give it a chance because I love this brand.

It works for me!
This product is helping with those annoying clogged pores. I believe it's fading a dark spot on my face slowly as well.
