So far I have the brush attachment for normal skin used the pink Extra-Sensitive heads are much softer and thus very suitable for sensitive skin.
For too long the face brush should of course still not be used, typically ranges from about one minute to clean the entire face. From the cleaning effect I notice any differences between the two brush heads. The sensitive attachment feels much more comfortable, as I have with the normal feel that the skin looks brighter and has better circulation.
The Sensitive brushes come in a double pack, they are not again individually packaged and without protective cap. I think that's a pity, because the packaging is a bit bulky and if you used several different brushes, do not you really do with it. Just like in the drawer I like them not to throw and will then keep the brush stock well in a Tupperware container.
