I bought my ClairiSonic Mia on a shop from home site (it was an amazing deal), and used one of the regular brush heads the came with it. I wasn't getting the amazing results I was expecting . Read a bunch of reviews from multiple sites, and several reviewers suggests these brush heads for people with sensitive combo skin (story of my life). Within a week, amazing difference. My skin is so clear, soft, supple and most importantly, clear with minimized pores. People are complimenting how dewy my skin appears, and that it appears to be glowing (and I'm not in a happy relationship or pregnant, is it must be the ClairiSonic and acne brush heads!
