Review (3/5): No instructions on how to use the product.
The serum seems nice and was easy to apply, however there were no instructions included in the box, the box itself had no English language. I really wanted to try this product, however I can’t give you an honest review if it works because I don’t know if the product should be applied once or twice a day, before makeup or at night. Directions need to be added to the product for an honest review.
