You know them by their more common name: sun spots. They look like a cluster of moles that appear in sun-exposed areas like your arms, face, neck, upper chest, and legs. The good news? While they’re related to how much sun exposure you’ve gotten, they don’t develop into skin cancer, Elbuluk says. The bad? They’re hard to tell apart from moles that could turn cancerous. Also, having a lot of them makes it even harder for you to examine your skin yourself—all the more reason to get an annual skin check from a board-certified dermatologist.
