will i purge again after upping my dose?

hello so i was on 20mg for the first month of my treatment and my skin had a significant purge where i broke out in cystic acne for 3 weeks (something i've never had)

now im on month 2 and my dermatologist upped my dose to 40... but i was wondering if it's possible for me to purge again? i have one active pimple as of right now and im 3 days into 40mg.

did anyone else experience a second purge or did your skin stay the same? (also for reference i have mild, persistent acne)
