"I really like this set. My skin feels so smooth as soon as I use the product and throughout the day. I'm about to purchase my second round of it and do believe it is helping with my crows feet. I'll know more on my second round. I used 4-5 drops the first week and think that was just too much. I recommend using 2 maybe 3 for your face. The kit lasted about a month but I didn't use it 2x a day as recommended on a consistent basis."
