Keratosis is a condition in which the skin develops thick, scaly patches. It is usually caused by excessive exposure to the sun or other environmental irritants. It can also be caused by certain medical conditions, such as psoriasis or eczema.
Causes of Keratosis
Keratosis is most commonly caused by prolonged exposure to the sun's ultraviolet (UV) rays. This can occur when someone spends a lot of time outdoors or works outdoors for long periods of time. Certain medical conditions can also cause keratosis, such as psoriasis, eczema, and other skin conditions.
Signs and Symptoms of Keratosis
The most common symptom of keratosis is the development of thick, scaly patches on the skin. These patches are usually reddish in color and may be itchy or painful. In some cases, the patches may become hardened and raised.
Diagnosing Keratosis
Keratosis is usually diagnosed by a physical examination of the skin. If the doctor suspects the condition is caused by a medical condition, they may order additional tests such as a biopsy or blood tests.
Treating Keratosis
The treatment for keratosis will depend on the cause of the condition. If the condition is caused by prolonged sun exposure, the doctor may recommend avoiding further exposure and using a sunscreen with an SPF of at least 30. If the condition is caused by a medical condition, the doctor may prescribe medications or topical creams to help reduce the symptoms.
