Understanding Different Types of Keratosis
Keratosis refers to various skin conditions involving thickened or rough patches. There are three common types:
Seborrheic Keratosis: Non-cancerous, wart-like growths in brown or black, usually seen in older adults. They’re harmless but can be removed for cosmetic reasons.
Actinic Keratosis: Precancerous spots caused by sun damage. These appear as rough, dry patches on sun-exposed areas and can turn into skin cancer if untreated.
Keratosis Pilaris: Often called “chicken skin,” this causes tiny bumps on the arms or thighs. It’s harmless but may be cosmetically annoying.
Causes & Risk Factors
Sun exposure is the primary cause of actinic keratosis. Genetics may play a role in seborrheic keratosis
and keratosis pilaris. Dry skin and hormonal changes can worsen keratosis pilaris. Fair skin and family history increase overall risk.
Diagnosis & Treatment
A dermatologist usually diagnoses keratosis visually; suspicious spots may need a biopsy.
Treatments include freezing, creams, laser therapy, or surgery, depending on the type.
Prevention
Use SPF 30+ daily, avoid tanning beds, and limit sun during peak hours. For keratosis pilaris, regular moisturizing and gentle exfoliation help.
When to See a Doctor
Seek help if a spot bleeds, grows, hurts, or concerns you in any way.
