Wanting to switch Botox clinic, looking for a doctor with a more natural touch

Hi, I’ve been going to the same clinic in Shinjuku for a few years but the results are becoming a bit too “frozen”especially my forehead area. Thinking of switching things up a little and find a different doctor who does Botox a bit more naturally and more for preventative results. Ideally English speaking doctor around central tokyo for easy commute. Any recommendations? Where does everyone go for Botox touch ups?
