Freckles are brown spots that commonly occur in sun-exposed areas on the skin. They're harmless and occur during puberty but can also develop at any age. As one gets sun exposure, the spots darken. When one avoids the sun or UV exposure, the spots lighten. The face is the most commonly affected area, but the arms and legs are quite common sites as well.
It is most common for one to have many of these lesions in an area, and not one or a few.
Freckles can be confused with “age spots” or moles (nevi), which do not get darker and lighter the way that freckles do.
Any lesion that has multiple colors, is larger than 4-mm, is asymmetrical, and/or has irregular borders should be checked by a board-certified dermatologist.
PREVENTION
As Sun-exposure, natural and/or artificial, makes them darker, avoidance is paramount. One should avoid midday Sun, wear protective clothing (i.e. wide brimmed hats and shirts), and use a broad-spectrum sunscreen that contains titanium dioxide and/or zinc oxide in high concentrations. Topical Vitamin C preparations can help prevent new spots and lighten existing spots.
IS LASER TREATMENT FOR FRECKLES NECCESSARY?
Everyone is different and no single treatment is best for everyone. Some treatments take time and patience, some leave crusts that take weeks to heal, some cost hundreds of dollars, and some cost as little as $35. So using different creams or tonics may not work, or even worse, can harm your skin if you don’t consult a dermatologist.
