Lentigos are flat brown marks. The most common type, the solar lentigo, is most commonly seen in middle age resulting from sun damage (age spots or liver spots). These are most often found on the face and hands and are larger and more defined than freckles. Solar lentigos are common in those with fair skin but are also frequently seen in those who tan easily or have naturally dark skin.
Although they are mostly considered to be of cosmetic concern and we do offer a variety of treatments to remove them, they are front and foremost a red flag that there has been significant sun exposure!
