try eucerin, cut your nails fully to avoid scratching, gently exfoliate to get rid of dry skin. also know your triggers, for example I can’t use bio washing up powder bc it reacts with my skin so I use non bio. drink plenty of water, avoid stress and consume (and it might make your skin itchy but maybe worth a shot?) coconut oil.
if you are using steroid use it for a short period of time, for a few days and make sure you are constantly moisturizing throughout. I personally hate E45, I use cetramacragol (yikez spelling) and if you want a thicker sort of Oiler one, hydromol (personally it didn’t work for me though)
try to avoid exposing yourself to hot water, have cooler showers and moisturize immediately
thankfully mines basically cleared up but I know the struggles lol, good luck! X
