27-year-old man with dark beard hair, light skin, and eczema on my neck — laser hair removal?

I’m 27, have dark beard hair and light skin. I often get eczema on my neck.

I want to get laser hair removal for my beard, but I’m wondering how this works if I have eczema. Do I need to wait until I have no eczema on my neck before getting the treatment?

The problem is that I can’t make an appointment in advance at a clinic, because I don’t know when my eczema will be clear.

How do people with eczema deal with this? Do clinics allow you to book an appointment only when your skin is clear?
