Crust

Crust is a term used in the medical field to describe a hardened layer that forms on the surface of the skin due to the drying of bodily fluids such as blood, pus, or serum. This is often a symptom of various skin conditions, including eczema, psoriasis, and impetigo.

Causes

Crust formation on the skin is typically a result of an underlying skin condition. These conditions can cause the skin to produce excess fluids, which then dry and harden on the surface of the skin. Some of the most common causes of crust formation include:

• Eczema: This is a chronic skin condition that causes the skin to become inflamed, itchy, and dry. In severe cases, the skin may crack and bleed, leading to crust formation.
• Psoriasis: This is a chronic autoimmune condition that causes the rapid buildup of skin cells. This buildup leads to the formation of scales and red patches that can be itchy and painful. In some cases, these patches can crack and bleed, leading to crust formation.
• Impetigo: This is a highly contagious skin infection that causes red sores on the face, especially around the mouth and nose. These sores can burst and produce a thick, golden crust.

Symptoms

The primary symptom of crust is a hardened layer on the surface of the skin. This crust is typically yellow or brown in color. Other symptoms can vary depending on the underlying cause and may include:

• Redness
• Swelling
• Itching
• Pain
• Bleeding

Treatment

Treatment for crust on the skin typically involves addressing the underlying cause. This may involve:

• Topical creams or ointments: These can help to reduce inflammation and itching, and promote healing.
• Antibiotics: If the crust is caused by a bacterial infection, antibiotics may be prescribed.
• Moisturizers: These can help to keep the skin hydrated and prevent further crust formation.
