I actually started with the brush of "normal" skin, which is slightly tighter / more than this one. As a "goodie" from Philips (if you registered there with the purchase on the website) I was then free them for sensitive skin. I am very satisfied, the cleaning effect is great, it is a soft feel and does not irritate. I do not feel that it is too soft and therefore not sufficient. Therefore, it is already ordered! Manufacturers recommendation is changed at least every 3 months.
