What works is using a healing substance such as (oat beta glucans & niacinamide & n acetyl glucosamine) twice a day. Cleansing your skin not too often. Protecting your skin with a good UVA covering sunscreen like L'Oreal UV Perfect with Tinosorb and Mexoryl (the best UVA protectors).
That's been healing my skin lately even better.
So I know there is hope.
Don't give up.
