According to Michael Valdes, M.D., a New Jersey-based plastic surgeon, while the spots and wrinkles appear to be superficial, the damage resulting from overexposure actually occurs on a cellular level. The sun fries your skin's DNA, causing cells to malfunction.
Extra melanin is produced, which accounts for brown blotches and freckling.
Fortunately, there's no need to run for cover. You want to make sure that any spot, damage or changes in the skin you're seeing isn't pre-cancerous. If you catch it early there's a cure, but you don't want to wait too long. Technically it's a Xenon flashlamp which emits intense pulse light. You can target age spots, broken capillaries with the pulse light and they break down and are absorbed by the body.
