I'm glad I started with these
I'm a 63 year old male--runner and basketball player.  I started the Prime and used these for about 3 weeks.  They really helped, but after 3 weeks they weren't enough to cleanse my skin deep enough.  I wanted something deeper so I went to a brush.  That satisfies.  I'm glad I started with these, but they weren't the long term solution for me.  I wouldn't have made it if I'd just started with the brush because it's so aggressive.
