Improve moisture barrier

If your skin feels dry/dehydrated and/or sensitive, I would recommend going for fragrance-free products (this would mean stoping Barbour and SkinCeuticals Metacell Renewal B3).

For the AM, I'd recommend a moisturizer like this https://whatsinmyjar.com/product/e-l-f-cosmetics-pure-skin-moisturizer or this https://whatsinmyjar.com/product/byoma-moisturising-gel-cream (more options here: https://whatsinmyjar.com/search/moisturizers/moisturizers-with-ceramides?ingredients_by_name=Niacinamide) plus a mineral based sunscreen: https://whatsinmyjar.com/search/sunscreens/mineral-sunscreens.

For the PM, go for a simple gentle cleanser:https://whatsinmyjar.com/search/cleansers/cleansers-for-sensitive-skin + a moistruizer. I'd use a heavier moistruizer (but no need for an extra serum step), for example, like this: https://whatsinmyjar.com/product/cerave-skin-renewing-night-cream
