Advice required for Tazoretene noob

I'm just starting off with boderm tazarene 0.05 percent.

So do I have a moisturizer, vitamin c serum, sunscreen and ofc the tazoretne.

Can someone guide me on how to incorporate all of the above.

Hoping for some solid advice from tazoretne veterans.

P.S I have oily acne prone skin with mild to moderate scarring.

Some people even say moisturizer isn't reqd a d what should the qty be.
