Review title is No instructions on how to use the product. [SEP] 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.
