Just prescribed tretinoin 0.1% for the first time

Hello! As the title says, I just got the prescription for trentinoin, which I’m super excited about. I am 25F and have been dealing with acne since I was a teenager, and I’m so tired of it. Right now, my routine is CeraVe Foaming Face wash in the morning, vitamin c serum, and SPF. Then at night it has been CeraVe cleanser again, Differin adapelene gel, and CeraVe intensive moisturizer.

How should I adjust this routine? Obviously I’m planning on stopping the adapelene, but I’m not sure if I should still be using the vitamin C or not. I am also a little nervous that they prescribed me 0.1%, and I am expecting irritation. The prescription says apply once a day at bedtime, should I consider going slower? TIA!
