Good MoleculesNiacinamide Serum

My dark-spot started to fade slowly…

My skin type Combination Skin leaning in oily in oily during summer and dry in winter.I was really excited to try this product out but after using it for just 2 or 3 days it made me breakout really badly and I knew it was this because the only thing I changed in my routine was this good molecules niacinamide serum. So, I stopped using it and in a week it almost went back to normal so I didn't use it for 2 weeks amd then wanted to test it again but this time just the Good Molecules Niacinamide Serum and a moisturizer.And again it made me breakout badly. So, I just stopped it. Or, Maybe it's the seller. I bought it from (ESTHETICA)
