Hi there I am very interested in buying one of the Kavi systems but dont know which to choose from. I have had acne my whole life. Right now I am 24 and have rosacea, severely dry skin and lots of cystic acne on chin and jaw line. I also get acne around my mouth area too. The thing is I would consider using the system for severe acne but with the rosacea and really dry skin I dont want to irritate my skin too much.. With the severity of my acne though I dont know if the moderate acne one would be better or if I need a combination of things or what?? Please help me out. thanks
