In some cases, a skin biopsy may be performed to rule out skin cancer, especially if the lesion is changing in shape, size, or color.
Treatment Options
Treatment varies based on the type of keratosis:
- Seborrheic keratosis often doesn’t require treatment, but removal options include cryotherapy (freezing), curettage (scraping), laser therapy, or electrosurgery.
- Actinic keratosis should be treated to prevent skin cancer. Options include cryotherapy, topical medications like 5-fluorouracil or imiquimod, photodynamic therapy, and chemical peels.
- Keratosis pilaris is usually managed with moisturizers, gentle exfoliation, and creams containing lactic acid, salicylic acid, or urea.
Prevention and Management
To lower your risk of developing keratosis, especially actinic keratosis, consider the following:
- Wear sunscreen daily with SPF 30 or higher.
- Avoid tanning beds and limit sun exposure during peak hours.
- Use moisturizing creams regularly to manage keratosis pilaris.
- Check your skin regularly for new or changing spots and consult a dermatologist for evaluation.
When to See a Doctor
While most forms of keratosis are harmless, seek medical advice if:
- A lesion becomes painful, bleeds, or rapidly changes.
- You are unsure whether a spot is benign or cancerous.
- You want to have lesions removed for cosmetic reasons.
In summary, keratosis is a broad term covering several skin conditions.
While many types are purely cosmetic, some carry potential health risks. Understanding the type you have is the first step toward effective treatment and peace of mind.
