Have been using the brushes for almost 2 weeks now and I can say that they are more gentile than the "sensitive" brushes! The bristles aren't as course! Would definitely recommend you try them for yourself! Great clean!
I was worried the delicate brush wouldn't be effective, but it's great! It's perfect for my sensitive/combination skin. Cleans without stripping and irritating.
I have rosacea so my skin is very sensitive. I have tried both the Sensitive and the Delicate brush heads and my face is much happier with the Delicate brush head. I use it with a Mia and I will clean my face this way every day twice a day for the rest of forever.
