trans | LHR for Chest and Back

Here is my situation. I'm 42 with dark hair and a light complexion. Not too much grey yet. I've had 4 laser sessions on my face. And I just started spiro (50mg 2x/day) last week. I plan to start E in 2-3 months.

I'm seriously considering having laser done on my chest and back. In fact, I made the appointment for 2 weeks from now. Am I being premature? Should I give the spiro 2 - 3 months to start working before I have my chest and back zapped? Or, like the beard, is it better to start now?

I'm looking for thoughts and experiences that anyone would like to share on this.
