I LOVED this serum. My skin ate it up and didn't have any reactions to it. Its hydrating and brightening. It actually did help with my stubborn dark marks as they've gotten lighter. Its perfect in the mornings as all I have to do is apply this, a moisturizer, and sunscreen and my skin feels cared for. Its really nice when my skin feels dry and not too much when it's feeling normal. It has a slight herbal scent to it which i personally like. Im about to repurchase another bottle and can see myself totally getting more in the future. 10/10 highly recommend!
