Some people are born with freckles, and others develop as a result of sun exposure. They may fade during the winter, but they come back darker every summer if you don’t take precautions to keep the sun’s rays off of your skin. They aren’t harmful to the skin, but some people prefer to lighten or remove them for a more even complexion. Freckles will reduce with all treatment modalities available. Most patients show an improvement > 50% after treatment in their freckling as long as daily sunscreen is used.
