This medication is used as a moisturizer to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations (e.g., psoriasis, eczema, skin burns and extra dry skin). Emollients are substances that soften and moisturize the skin and decrease itching and flaking. Some products (e.g., zinc oxide, white petrolatum) are used mostly to protect the skin against irritation (e.g., from wetness). Absorbase is a major part of psoriasis therapy - with application applied at night, works while you sleep.
