I've only been using it for a week, it will take some time to see if it works on stains. It's a bit sticky serum and doesn't absorb very easily, it stings a little on my skin

I'm on my second bottle of this serum, I use it in the evening and leave for 20 minutes before applying cream. It really made my skin colour even after vacation in sunny region. My beautician had doubts if peptides would really brighten, I'd say they do nice job.

Make no mistake, a 30 ml bottle of Re:Pigment is not enough to get rid of dark spots. But with continued use, the results are truly amazing. Niod is a great brand and this is absolutely my favourite serum!

I’m a huge NIOD fan for many years, but this serum is not my fave one. Yes, it works, but it takes moths to show results and only, if you don’t have a lot of pigmentation. Repurchased it 3 times in the past. 

Without doubt has significantly reduced my pigmentation. Nothing else on the market I have found that is as effective
