Tretinoin beginner routine

Hello reddit fam, after lurking through multiple subs, I’ve started my tretinoin journey at the age of 28 as a brown-skinned girl who has suffered from hyperpigmentation, melasma, and acne-prone skin (now with pitted scars). The routine I’m following right now is shared below. Please share your feedback :)

Tret routine (using Tretin 0.025%):

Night time only

Sandwich method with CeraVe Baume Hydratant and Vaseline petroleum jelly at the end (to lock everything in)

Aziderm 20% gel (morning, every day)

Sandwich method with Dot & Key Ceramides Barrier Repair Cream and sunscreen (using Minimalist SPF 50++ right now)

I don’t want to disrupt my skin barrier at all.
