How is asteatosis defined?

Asteatosis is characterized by dry, scaly skin that results from a deficiency in sebum production. Sebum is the natural oil produced by sebaceous glands in the skin, which serves to lubricate and protect the skin’s surface. When sebum levels are low, it can lead to a compromised skin barrier, resulting in dryness and a flaky appearance. This condition does not involve excess oil production or the presence of oily skin, which differentiates it from other skin conditions related to oil. Additionally, asteatosis is not specifically associated with skin infections, and while dry skin can sometimes become more susceptible to infections, that is not the defining characteristic of asteatosis. Overall, the definition emphasizes a lack of moisture and protective oils rather than an overproduction, making it essential to recognize and address the underlying causes of this condition.
