There's no real cure for it. It's an immune disorder. The steroid cream is an immune suppressant, that's why it's "effective".

See it from an allergy point of view. You're allergic to something & each time you triggered your allergy, your eczema flares up. So try to identify what triggers your eczema & avoid it like a plague.

Also, stop taking sugar & gluten may probably help too. Focus on eating clean.

Focus on internal healing, it's better for autoimmune disorders in the long term. Despite me being an eczema skincare seller, I still tell people that.

You go 2nd, 3rd or more rounds to the doctor, they'll just give you a higher dose of steroid only. The purpose is just to suppress the immune system & let your body heal by itself over time. Sometimes the triggers are still active, so that's why even after the steroid effect is over, the eczema will flare back up again. Nothing our modern meds can cure eczema. Just manage the flare ups only.

If you focused on skincare, that's external healing. If focused on dietary care, that's internal healing.

In a nutshell, avoid inflammatory food such as sugar, gluten or processed food. Eat more immune boosting food.

If he has other problems as well, then ideally seek a nutritionist or dietitian opinions too in order to get the right balance.
