How to remove facial hair while on adapalene?

So I started my journey with adapalene about a month ago and I am very happy with the results. I waxed my upper lips recently and the skin was mildly damaged(paused the treatment and used only moisturiser for a week for healing). I’ve been waxing upper lips for years so it was definitely the effect of adapalene. I don’t want to shave/thread off upper lips. What facial hair removal method do you use while using adapalene? What precautions should I take next time. Is epilating safe?
