Age spots and actinic keratosis are both skin conditions, but they are very different. Age Spots
Age spots, also known as liver spots, are flat, round patches of discoloration that appear on the skin. They are usually brown or black, and they typically appear on the face, hands, arms, and shoulders. Age spots are caused by sun exposure and are most common in people over the age of 40. They are harmless, but they can be a cosmetic concern.
Actinic Keratosis
Actinic keratosis, also known as solar keratosis, is a precancerous skin condition. It is characterized by rough, scaly patches of skin, typically on the face, scalp, ears, arms, or hands. Actinic keratosis is caused by long-term exposure to ultraviolet (UV) radiation, such as from the sun or tanning beds. It can be treated with topical medications, cryotherapy, or other treatments.
