Freckles are groups of skin cells (keratinocytes) that contain melanin, the brown skin pigment. The skin cells are otherwise perfectly normal, so the spots are flat and cannot be felt. They do not cause a lump. The melanin is produced by a specialized cell called a melanocyte. Exposure to sunlight stimulates the melanocyte to increase the amount of melanin it makes and the pigment seeps out and is picked up by the surrounding skin cells. That’s why the color appears in spots, instead of uniformly across the skin. Areas that lack melanocytes do not freckle. Since people generally get more sun exposure in the summer, they tend to freckle more at that time. .
