HERE’S WHAT YOU NEED TO KNOW AND…

Types of Keratosis

Seborrheic Keratosis: Non-cancerous, wart-like spots in shades of brown or black. Common in older adults and usually harmless. Actinic Keratosis: Precancerous patches caused by sun damage. Appears as rough, dry spots on sun-exposed areas and can lead to skin cancer if untreated. Keratosis Pilaris: Known as “chicken skin,” this causes small bumps, usually on arms or thighs. It’s harmless but may be cosmetically bothersome.

Causes & Risk Factors

Sun exposure is the main cause of actinic keratosis. Genetics may contribute to seborrheic keratosis and keratosis pilaris. Dry skin and hormonal changes may worsen keratosis pilaris. Fair-skinned individuals and those with a family history are at higher risk.

Diagnosis & Treatment

A dermatologist can typically diagnose keratosis by examining the skin. If a spot looks suspicious, a biopsy may be done.

Seborrheic Keratosis: Can be removed if needed via freezing, scraping, laser, or electrosurgery. Actinic Keratosis: Requires treatment (freezing, topical creams, or light therapy) to prevent cancer. Keratosis Pilaris: Managed with moisturizers and exfoliating creams.

Prevention

Wear SPF 30+ sunscreen daily. Avoid tanning beds and limit midday sun. Use moisturizers for keratosis pilaris. Monitor skin for changes and consult a doctor if needed.

When to See a Doctor

Seek medical advice if a lesion: Becomes painful, bleeds, or changes quickly. Looks suspicious. Is bothersome and you want it removed.
