everyone has moles some place on their body. Dont be insecure, your unique! Being unique makes you beautiful! Cindy Crawford has a mole on her face and she is labeled as one of the most beautiful women in the world.
There's nothing wrong with them. Most people don't notice them. If you have a large one that's irregular-shaped, 2 colors, or raised, you should go to a dermatologist to get it checked out because it could need removing.
