What worked for your dry flaky skin

So I am recovering from a bad eczema flare up. It got triggered due to dry weather conditions. And when I say bad, it got really bad. After using steroid and making other wrong choices, I finally simplified my routine and it helped in my skin recovery to a large extent:

1. Reduced using skin cleanser to minimum. Use only water as much as possible and other times use oats based non foaming cleanser.
2. Apply Cosrx peptide serum, aloe vera gel and Aveeno moisturiser as frequent as possible
3. Apply LRP Cicaplast at night time.

This helped in controlling the flare up to quite a large extent but my dry, flaky and irritated skin around my mouth area is not recovering completely. I wanted to check if any specific holy grail product helped you with the dry flaky skin issues and its maintenance over time.
