Is it normal for purge to stop on forehead first?

[Prokopton]

So I recently started using glycolic acid 2x per week, I believe around 4-5 weeks ago, It started purging around week 2, and now my forehead acne/purge went away, but my midface and nose is still kinda stubborn, I was wondering if anybody else had dealed with this, and how much longer after forehead purge ends, did your midface and nose purge end.

its pretty normal for different zones of your face to purge at different times like your forehead cleared faster since it has thinner skin and cell turnover is faster than other areas on your face like your nose and midface
i cant say how long it took my purge to end since i havent used glycolic acid before
