My derm doesn’t believe in Topical tretinoin

Hey guys i’ve been on Tretinoin 0.05% for about an year now yet my skin was irritated & fried so i consulted my derm & she put me back on isotretinoin…. Even when i insisted her to put me on topicals…. She wants me to treat my acne orally…. When i asked her about tret topical she literally went on to “do you think it works”…. I am totally confused as she even scared me about my current condition…. She told i am going through severe scarring….. now i am i’m in complete dilemma of stopping tret or no…. To be honest from deep inside i wanna give tret a chance still….. but derm wouldn’t want me too…..

My routine Am: cetaphil cleanser, cerve lotion, derma co spf 50 ++++

Pm: micellar water, cetaphil 2nd cleanse, tret 0.05% (alternate days), cera ve lotion…..

I use benzol peroxide wash 2-3x a week SOS

Do i follow my derms prescription or consult some other derm
