When I wax my arms I develop a reaction/acne on only my upper arms that lasts at least a month or two. Should I try laser?

I've tried different kinds of wax including organic sugar wax. My dermatologist prescribed mometasone furoate cream to use after waxing, which helped only the first couple of times. The only thing that has always helped is being in the sun/tanning, but the weather's gotten colder now and I'm hesitant to go artificial tanning. Is there anything else I can do to help avoid this altogether or to speed up the process of healing it? Should I just not wax anymore and instead do laser hair removal?
