On the box, where it is reviewing the test results, it says that women who used the product twice a day saw a reduction of oiliness. So, if you are using this product to reduce oil than yes use twice a day. If you are only using this product to reduce the size of pores, than I would suggest only using it one a day, to spare the product, it is really expensive!

I only use it during the day (alone and under makeup) because I use another product at night. I have found benefits from the once a day use already.
Only in the morning; prior to applying my make up or use alone.
