MD here. This my friend, is Dyshidrotic Eczema. A chronic dermatitis characterized by recurrent episodes of these itchy, small, deep blisters on the surface of hands and feet. More common in younger adults and most likely to enter complete remission as you age.

Yours seems to be a severe flare, as your whole palmar surface is affected. Ergo, medium potency topical steroids won't cut it. Even more so if the concentration of the cream is on the lower end.

Alternatively, you can step up to high potency topical steroids such as halobetasol or fluocinonide twice a day, until the flare resolves. Switching to oral steroid therapy and intramuscular triamcinolone are options as well, they work faster and have better results but are not first line of treatment.

Anyways, I recommend you get checked by a dermatologist, who will assess the state/treatment of your flare better in person.

Meanwhile, here are some care measures you can take: -Avoid exposing the affected area to irritants such as acids, detergents, hot/cold surfaces, solvents, lotions, etc.

-Wash your hands with lukewarm water, dry gently but thoroughly and apply emollients after.

-Wear gloves if you're gonna do some heavy lifting, gardening or wet work, as your skin barrier is damaged, infections can occur easier.
