Freckles and moles have different causes, colors, and textures, commonly occurring on various areas of the skin. Freckles frequently appear as small, flat brown dots, while moles may be small or large, flat or raised, and brown or black in color. Neither are dangerous on their own, but both moles and freckles should be carefully monitored. Changes in either could be an early warning sign of skin cancer or other sun damage-related conditions. It’s important to talk to a dermatologist about any freckles or moles you’re concerned about.
