Seborrheic keratosis (Age Spots)
Moles, seborrheic keratoses (age spots), skin tags and warts are non-cancerous growths that are quite common.
Seborrheic keratosis are known as age spots, liver spots, sun spots, senile lentigo and solar lentigines, These are flat or slightly raised, and can appear as black, brown or even grey spots on the skin.
Age spots come about when there is an excess localized production of melanin, or skin pigment, that occurs with skin aging and ultraviolet light exposure. Age spots are therefore seen on skin that receive the most sun exposure, like your face, shoulders, back, upper forearms and the back of hands. Patients who experience age spots are commonly over 40 years of age, have fairer skin, and have a history of frequent sun exposure or use tanning beds.
Age spots can be removed by an ablative laser, which removes the raised pigmented skin. I prefer to use an Erbrium Yag instead of a CO2 laser, as there is less risk of post inflammatory hyperpigmentation.
