Would you believe that people with lots of moles are less likely to get wrinkles and other signs of aging? According to AOL Health, moles form when cells separate quickly, producing darker-colored spots on the skin. They can start to appear in children as young as age 4, are usually scattered all over the body, and in some people, moles continue to multiply as they get older. Their complexion remains smoother and without lines, so they look younger. Researchers at King's College in London studied more than 1,000 identical and fraternal twins between 18 and 80. The result: Those with more than 100 moles had fewer wrinkles and sturdier bones and muscles, and they were half as likely to get osteoporosis as women with fewer than 25 moles. That's because people with many moles produce white blood cells with extra long chromosome tails that carry extra DNA. The more spare DNA in your cells, the more times the cell can reproduce before it dies. However, the number of moles isn't the biggest predictor of how well you'll age. Dr. Joshua Zeichner is the director of cosmetic and clinical research at Mount Sinai Medical Center. He says that skin pigment or melanin protects your skin from age-related issues. That's why African Americans often look young deep into their 60's, and people with less melanin, like Caucasians, experience more damage from the sun, and look older and more wrinkled at a younger age. Bottom line: If you want to slow the aging process, limit the time you spend in the sun. Because doctors say sun exposure and genetics determine when you'll get wrinkles on your face - and how severe they are. If you have a lot of moles, know this: The marks may be the first signs of skin cancer. So, keep an eye out for changes in any of your moles - and see a dermatologist at least once a year to get your spots checked.
