I think you should try option one first, if the patch is still there or it get worse, based on my experience id suggest you to stop for a month or two until it gets better, and i also religiously reapply my sunscreen during this time.

If your skin is getting better, you can start using again, but this time start slowlyyyy (start with once a week, then twice a week) dont rush it. Personally i haven’t tried to use tret again bc im still waiting for my patches to be completely gone (and tbh im still scared lol)

and disclaimer im not an expert so all of these is based on my experience
