It can take weeks or months for psoriasis on the palms and feet to go away. Strong steroid creams can thin the skin, thus while Halobet Cream may assist with redness and scaling, it should not be used excessively for extended periods of time without a dermatologist's supervision. Wear comfortable shoes, avoid harsh soaps and scratching, keep your skin properly moisturised, and try to minimise stress, all of which can exacerbate psoriasis. Please see your dermatologist again if you haven't improved after a month. You could require an alternative course of treatment, such as stronger moisturisers, vitamin D creams, phototherapy, or other medications.
