Xerodermia is a medical condition commonly known as dry skin. The term refers to the skin becoming dry and itchy due to the lack of moisture. Some synonyms for xerodermia include ichthyosis, asteatosis, or pruritus. Ichthyosis is a skin condition that causes the formation of scales on the skin surface, while asteatosis means a lack of sebum in the skin. Pruritus refers to the sensation of itchy skin. Xerodermia can cause discomfort and even lead to cracking, bleeding, and increased risk of infections. Treatment involves hydrating the skin and using moisturizers to maintain its suppleness and moisture levels.
