This serum has really helped

This serum has really helped brighten my skin and smooth out the texture! I'm on my second bottle. If I use it twice a day I can feel a little bit of a burning sensation, but it's good if I only apply it once a day.

I love this Niacinamide 15

I love this Niacinamide 15 serum. It is one of the best Niacinamide products I have tried and also very reasonably priced for its effectiveness. It is one of the only serums that I can see noticeable brightness and a little improvement in fine lines the day after I use it. I will continue to use this serum regularly.
