I haven’t used this for so long but when I do my face is glowing and i don’t look as dull. It’s great and dries down quickly and it’s not sticky which I prefer.

Burned my skin and gave it red spots

I've tried several Byoma products (the cream and the hydrating serum) which I liked a lot. However on the first look similar ingridients, this serum does not make my skin soft en smooth like the hydrating serum and the cream do. I don't notice much effect from this serum. I will continue using the bottle, to see if there are any brightening effects after a while, but I will not buy it again.

This is my second bottle and I am pleased with the results. Simplistic, affordable, layers nicely, and delivers respectable results. By far the best cheap niacinamide serum for sensitive skin.

I use this serum after my retinol in the evenings. I really like the consistency. You don’t need much. I would repurchase. 

I use this serum when using retinol and it helps me to calm down the skin and to protect any side effects of the retinol. I use it twice a day a little goes long way and its wonderfull serum for such a good price. Thank you Cultbeauty you have this mark in your portfolio.

This serum is a good budget niacinamide. It doesnt feel sticky and it doesnt break me out like the ordinary one does. Little goes a long way.

I have dehydrated, acne-prone combination skin. I was looking for a serum with niacinamide that also gives some extra hydration. I've used the niacinamide serum of the ordinary, but I didn't like that because it was too agressive for my skin. I use this along with BYOMA's gel cream and it is a great combination. My skin feels less tight and more supple. I will definately buy this again!

This serum did absolutely nothing for my skin. The serum is a little greasy so you feel it on your face for quite some time. The dropper works great but the serum is not for me - maybe for people with very dry skin.

This serum is brightening, plumping and hydrating. I use it with retinol.
