Tretinoin forehead brreakout

Hi all,
I recently started Tretinoin 0.5% cream nightly not so much for acne but to have smooth skin and prevent wrinkles.
I know it's normal to have some skin redness and peeling, and I've had only a small amount 1 week into it.
My question is, is it normal to have small breakouts on my forehead?
Also, can I mix the tretinoin with a moisturizer at night to make it less drying?
Thanks a lot
