This niacinamide serum is very good! I don't know the percentage of the active compound present, but i noticed that my face is a bit more iluminated after starting to use this product. i recommend you to try!

This is such a great product it left my skin feeling so fresh all day. Lovely packaging too.

I don't know about the brightening.. but I enjoy using this nonetheless! My skin feels extra hydrated when I use this before my moisturizer. Plus I feel like it plumps the skin around my eyes.

This product is so good I have extremely sensitive skin and this product didn't irritate my skin one bit. It is a very nice product and pairs really well with the hydrating serum!

It was good not great, nothing bad to say about it but nothing spectacular either
