Scale (dermatology)

Scale (dermatology)

Psoriasis, a common skin condition that causes scales.

A scale in dermatology refers to a visible peeling or flaking of layers of the skin. Scales are typically dry, white, and flaky, but can also be thick and waxy. They are a common symptom in many skin diseases, including psoriasis, eczema, and seborrheic dermatitis.

Causes

Scales can be caused by a variety of factors, including:

• Inflammation: This can occur as a result of an immune response to an infection or injury. Inflammation can cause the skin to produce more cells, leading to scaling.
• Dry skin: This can cause the skin to flake and peel, leading to scales.
• Skin diseases: Many skin diseases, including psoriasis, eczema, and seborrheic dermatitis, can cause scales.

Symptoms

The primary symptom of scales is the visible peeling or flaking of the skin. Other symptoms can include:

• Itchiness
• Redness
• Pain
• Swelling

Treatment

Treatment for scales depends on the underlying cause. Common treatments include:

• Moisturizers: These can help to hydrate the skin and reduce scaling.
• Topical steroids: These can help to reduce inflammation and scaling.
• Antifungal medications: These can be used to treat scales caused by fungal infections.
