Dimethicone is a drug commonly used as a moisturizer to treat dry, rough, scaly, itchy skin and mild skin irritation (eg, diaper rash, burnt skin due to radiation treatment). Emolient is a substance that softens and moisturizes the skin and relieves itching and flaking. Some products (eg, zinc oxide, white petrolatum) are mostly used to protect the skin from irritation (eg, from wetness). Dry skin is caused by lack of fluid in the upper skin layer.
