I feel you bro, same sort of thing I suffer from.
I use moisturisers - usually of the emollient variety, avoid dairy and get some sun around you - avoid the sunbeds though (my girlfriend is a dermo-nurse and swears this will do more harm to the melanin than good. UV light treatment in a hospital is not a sunbed, it is very different). Also cauliflower and broccoli are really good - the rawer the better.
Take care man, and if you haven't already, go ask your GP for a referral to the Dermatology clinic asap, those guys are great and at the moment they are pretty much empty, but still operational as the hospitals wind down their response to Covid.
