What is this Halobetasol 0.05% w/w + Salicylic Acid 3% w/w Ointment used for?

This ointment pairs a strong steroid with an ingredient that softens thickened skin, and it's typically used for stubborn patches like psoriasis or eczema that haven't responded to milder treatment. Because it contains a potent steroid, it's meant for limited use on the specific area your doctor points to, since prolonged or widespread use can thin the skin or cause other side effects. It really is best used under a dermatologist's guidance rather than on your own.
