Those Little White Spots? Understanding Stucco Keratosis on Your Feet

Have you noticed small, white, slightly raised spots on your ankles or the tops of your feet? They might feel a bit rough, like sandpaper. If so, you could be dealing with a skin condition called stucco keratosis. Don't worry though, it's a common and harmless skin condition. Read on to learn what it is and how to manage it.

What is Stucco Keratosis?

Stucco keratosis, also known as keratosis alba, is a skin condition characterized by small, dry, white or greyish-white, scaly lesions. They typically appear on the ankles, tops of the feet, and sometimes the lower legs.

The lesions are often easy to remove but then grow back quickly again. It can easily be mistaken for other skin lesions such as warts. Stucco keratosis is not associated with any other conditions but it's appearance may concern some patients.

Although thought to be common, stucco keratosis is a condition which has been under researched and may be more common than we think.

What does stucco keratosis look like?

• Appearance: They are usually 1-4 millimetres in diameter and have a flat topped "stuck-on" appearance, resembling paint splatters. They can be round, oval or have irregular borders. You may just have a few or several hundred.

• Texture: They feel rough & dry to the touch, similar to sandpaper.

• Location: Most commonly found on the lower extremities, particularly in sun-exposed areas.

• Cause: While the exact cause isn't fully understood, sun exposure, ageing, and dry skin are believed to be contributing factors. It is more common in older people.

• Symptoms: Stucco keratosis generally have no symptoms but occasionally are itchy.

How to Manage Stucco Keratosis:

While stucco keratosis is generally harmless and doesn't require treatment, many people seek management for cosmetic reasons or to relieve dryness. Here's what you can do:

• Moisturising:

  Regularly apply a good quality emollient or moisturiser to the affected areas. This can help soften the lesions and reduce dryness. Look for products containing urea and lactic acid, as these ingredients can help exfoliate the skin and gently remove them.

• Exfoliation:

  Gentle exfoliation with a soft washcloth or a mild exfoliating scrub can help remove the surface scales. However, avoid harsh scrubbing, as this can irritate the skin.

• Sun Protection:

  Protect your skin from excessive sun exposure by wearing sunscreen with an SPF of 30 or higher and protective clothing. This can help prevent the development of new lesions.

• Physical removal:

  Generally physical removal is not advised as this may damage the skin leading to irritation, infection and scarring.

When to See a Podiatrist:

• If the lesions are causing discomfort or pain.

• If you notice any changes in the appearance of the lesions, such as redness, bleeding, or rapid growth.

• If you're unsure whether you have stucco keratosis or another skin condition.

• If home care does not improve them.

• If you have diabetes or other conditions that impact skin health.

By understanding what stucco keratosis is and how to manage it, you can keep your feet looking and feeling their best. Remember, regular foot care and sun protection are essential for maintaining healthy skin.
