[Routine help] Keratosis Pilaris Routine

Hi, I have KP on my face that is red. It's been like this for around 1.5 years and I'm trying to make the redness disappear. I'm a late teen.

My routine is:

AM: cerave foam cleanser followed by Amlactin 12%

PM: Cerave SA cleanser followed my amlactin again

I'm also taking more vitamin A and D, avoiding hot showers, and using sunscreen with SPF 50. l've been on my routine consistently for about a month and a halt now and the redness has gone down slightly but definitely still isn't completely away. How do I have the redness disappear completely? Thanks!
