Use Aqueous cream in the shower. It's a soap substitute & very cheap over the counter. Apply and lightly rinse off. Don't rub. Pat yourself dry. Helps to moisturise skin & is recommended for eczema conditions.
Our skin is an organ just like liver, kidneys, brain etc. If you've got some internal "inflammation" it can show in your skin. Getting to the source of that can be challenging. Could be something you eat or a lack of a certain mineral or vitamin? See a skin specialist when C19 relaxes maybe? Good luck. I hope it gets better soon & our posts have been helpful.
