Solar keratosis, also known as a sunspot, is a small, scaly patch of skin caused by long-term exposure to UV radiation from the sun. They are most commonly found on areas of the body that receive the most sun exposure, such as the face, hands, and arms. Solar keratosis is typically benign, but it can sometimes progress to actinic keratosis or even skin cancer if left untreated.
Symptoms of Solar Keratosis
The symptoms of solar keratosis include small, scaly, and slightly raised patches of skin that are rough to the touch. They are usually pink, red, or brown in color and can range in size from a few millimeters to several centimeters. Solar keratosis is typically painless, but it can sometimes itch or bleed.
Treatment of Solar Keratosis
Treatment options for solar keratosis include cryotherapy, which involves freezing the lesion with liquid nitrogen, or topical medications such as imiquimod, which stimulates the immune system to attack the abnormal cells. It is important to note that while solar keratosis is typically benign, it can sometimes progress to actinic keratosis or even skin cancer if left untreated.
In my clinic I use cryotherepy to effectively treat these sun spots and lesions, after a thorough check to ensure the diagnosis.
