Haster Lotion is a dermatologist-prescribed topical corticosteroid containing Halobetasol Propionate 0.05% w/v. It is used for the treatment of inflammatory skin conditions such as psoriasis, eczema, and dermatitis. Halobetasol is a super-potent corticosteroid that reduces redness, swelling, itching, and discomfort by suppressing inflammation and immune responses in the skin. Due to its potency, Haster Lotion should be applied only to affected areas and for the duration recommended by a physician to avoid side effects.
