Theres nothing really bad on this product.  

Its really good and does not cost too much money. Its good for oily skin.
+ it smells great, like grapes!

its a little heavy on my oily skin so i recommend to not use this product if you have oily skin

it irritated my under eye area. i dont really recommend this on sensitive skin

it brightens a little and feels refreshing

Its a little sticky and sometimes foamy. 

This serum helped me with redness and breakouts a lot. I also liked the consistency.

I had really big expectations about this product and it wasnt that good. I thought it will help my closed comedones as i heard about this product.

When i used this regularly i noticed that it reduced my blackheads a little.
