Must Have Cleansing Tool
The only slightly annoying thing is having to replace the brush head, which cost $35 each or $59 in a pack of two. Still, each head lasts about a month. When I made the purchase initially, I was worried about bacteria building up in the bristles, but I have been impressed in that the claims that the bristles prevent bacteria build-up seem to be true. I never go anywhere without my Clarisonic and will definitely replace it if it ever dies.
In terms of acne treatment, I wouldn't say that the Clarisonic cures acne all by itself but it is the best way to clean the skin before other acne treatments such as clay masks, lotions, creams etc. I personally cleanse with the Clarisonic, apply witch hazel and the Love System moisturiser before using the Neutrogena light therapy mask. This routine has cured my acne.
