I'm glad I purchased this dermal roller. I felt the size was good for my skin as I have never used one before, but my skin is used to vitamin C serum and retinols. I definitely can tell a difference if I use the dermal roller prior to serums at night or in the morning. I try to use it daily. Definitely worth a try if you're on the fence!
