I've read here on this subreddit (don't remember the post/comment unfortunately) that you're supposed to switch the place where you put your gel on every once in a while to avoid the area building up "resistance" to it and slowing down absorption.

My endocrinologist hasn't mentioned this at all during our meetings, and I'm getting mixed results online. In your experience, has changing the application area help?

I wash my upper arm every day with hot water before putting it on (my right arm usually). Should I be changing it up?
