For a long time only Clarisonic brush head I've tried was the one for sensitive skin. A while ago I thought that my oily skin needs a bit "stronger" brush head so I got one for normal skin. At first I didn't notice any difference but after some time it became too overwhelming for my skin if I use my Clarisonic twice a day. So right now I use it only at night and it is a perfect combination. I'm not sure about repurchasing it, maybe I will go back to brush for sensitive skin and use it twice a day or maybe I'll keep buying one for normal skin, I haven't jet decided.
