Solar lentigines (also known as “freckles” or “sun damage spots”) are usually found on the chest, upper back, and face. What do all of those locations have in common? They are hot spots for excessive sun exposure and sunburn. Over time, the body responds to ultraviolet light by increasing local proliferation of melanocytes (the color cells in your skin). These spots are more common in fair skin individuals, but can be seen in all skin types. These spots should be all one color with very sharp borders, but can often be difficult to distinguish from an abnormal mole or even melanoma. If your solar lentigo is more than one color, raised in any area, if you notice abnormal borders, or if you have any concern that one of your spots is abnormal, you should schedule an appointment to see your dermatologist.
