To treat or prevent dry, rough, scaly, itchy skin and minor skin irritations, this drug acts as a moisturiser. Emollients are chemicals that soften, moisturise, and reduce flaking and irritation of the skin. Some products are primarily meant to shield the skin from irritation. The top layer of skin loses water, which leads to dry skin. In order to keep the skin moist, moisturisers create an oily layer on top of the skin. Common emollients include petroleum, lanolin, mineral oil, and dimethicone. Altogether gives soft and brighter looking skin.
