As the name suggests, this brush is suitable for sensitive skin. The threads are softer than that of the normal brush. I have two brush heads and have been thought to have a normal skin. Nevertheless, my skin is still very very red on the application with the normal attachment for a long time after use. That's why I switched to this essay. Cleaning is just as intense, the skin is supplied with blood, but after a short time the skin looks normal again. Before I was rather unpleasant to go out of the house, while my face was totally red. I'm using at the moment the attachment for sensitive skin for the reasons mentioned in the morning, the normal attachment for the evening. I think I'll buy more only this essay for my skin and do without the other.
