Lentigines (Plural) – Lentigo (Singular)

This term describes brown blotchy marks of different shapes and sizes on sun exposed skin of hands, forearms and face.

Best thought of as large freckles, these darken in summer and tend to fade in winter, though never completely. They are flat and smooth on the surface, not lumpy.

They are very common in Australia and a sign that the skin in the area has had enough lifetime sun exposure, often with multiple sunburns.

Cutera’s LimeLight IPL can effectively reduce the appearance of these irregular brown blotches.

Lentigines or Lentigo
A lentigo (plural lentigines) is a small, pigmented flat or slightly raised spot with a clearly defined edge that is surrounded by normal-appearing skin. Lentigo or lentigines may evolve slowly over years, or they may appear suddenly. They may occur anywhere on the body and vary in colour from tan-brown to black. Viewed under the microscope a lentigo shows an increased number of normal melanocytes (skin cells that produce the pigment melanin that produces skin colour). Melanocytes appear to replace keratinocytes in the basal layer of the epidermis.
