Scales

Definition

Scales are a visible peeling or flaking of outer skin layers. These layers are called the stratum corneum.

Alternative Names

Skin flaking; Scaly skin; Papulosquamous disorders; Ichthyosis

Causes

Scales may be caused by dry skin, certain inflammatory skin conditions, or infections.

Examples of disorders that can cause scales include:

Home Care

If your health care provider diagnoses you with dry skin, you'll likely be recommended the following self-care measures:

If your provider diagnoses you with a skin disorder, such as an inflammatory or fungal disease, follow instructions on home care. This may include using a medicine on your skin. You may also need to take a medicine by mouth.

When to Contact a Medical Professional

Call your provider if your skin symptoms continue and self-care measures aren't helping.

What to Expect at Your Office Visit

Your provider will perform a physical exam to look closely at your skin. You may be asked questions such as when the scaling began, what other symptoms you have, and any self-care you've done at home.

You may need blood tests to check for other conditions.

Treatment depends on the cause of your skin problem. You may need to apply medicine to the skin, or take medicine by mouth.
