i bought this serum for my husband and it is stinking! even i'm not using it, but the smell is so bad that makes me sick. Not sure does it makes dark spots lighter, didn't see any improvement since husband using it for 3 weeks now.

Will not buy again. Does not seem to work on me.

My holy grail! Buying 2nd bottle of this. My 1st bottle is jot finished yet. That is howmuch i love this stuff. Lighten my acne scars n somehow lessen future breakouts. Smell strong but it works!

Loving this product, lightens scar, into my 3rd bottle now.

smells good, non greasy for oily skin , but haven't feel the difference for brightening effect, will continue to use it to see the difference.

i have been using it for a while my skin got worse

I used it for two weeks, the spot seems reduce and the skin turn smooth. Good

I like how this seems to help firm my skin but it hasn't helped fade my brown spots. I've used about four bottles at least. Disappointed. I go to a lot of effort to try and find products that have good and clean ingredients of which I found this product to have.

Already used 2 bottles, will keep using it.

very effective for dark spot, and whitening skin with this prices, it's very good
