This item comes in a
[This review was collected as part of a promotion.] This item comes in a dark black bottle for a reason, yet I used it no more than 8 times and it was already empty. It appears the bottle was filled less than halfway from the start. I’m extremely disappointed by the lack of honesty from this company. While the product itself is effective, the misleading packaging and underfilled bottle have pushed me to look for another Korean alternative

Liquid miracle
