Solar Lentigo, Liver Spots
What Is It?
As you age, years of being in the sun start to add up. Age spots (also called liver spots or solar lentigo) are collections of pigment caused by exposure to the sun. Pigment is deposited as a form of response to injury just like a scar is a response to a cut. The pigment collects in areas injured because of thin skin or greater sun exposure. Age spots also can be caused by bruising that leaves blood pigments behind. They are most common in people over age 55. The spots commonly appear on the hands, but can be almost anywhere, especially sun-exposed areas such as the face, back, arms, feet and shoulders.
Symptoms
The only symptom is the appearance of darkened spots on the skin. They do not itch and are not painful.
Diagnosis
You can diagnose age spots yourself by their appearance. If you are concerned about changes in your skin, contact your doctor. He or she can do tests to rule out other diseases.
Expected Duration
Most age spots fade over time but probably will not disappear because the skin has been damaged.
It is a similar process to scar formation in that scars are often heaped up when they form, and soften as they “remodel” over time.
Prevention
By limiting your sun exposure, you can decrease the possibility of age spots. Sun exposure under the age of 20 is the major factor that determines how your skin will look in later life. If you already have age spots, limiting your exposure to the sun can help prevent them from enlarging or darkening.
To protect your skin from the sun, wear long-sleeved shirts, pants and a hat. Use sunscreen if you will be outside for more than a few minutes. Avoid being in the sun during midday (10 a.m. to 3 p.m.), when the sun’s rays are the most intense.
Treatment
No treatment is necessary for age spots. Creams sold in stores will not lighten the spots. There are some newer medications prescribed by dermatologists that can lighten some pigmented areas, but these should be used sparingly. Creams also are available to cover them for people who feel self-conscious.
When To Call A Professional
If you are concerned about changes in your skin, contact your doctor. He or she can rule out cancer or other underlying medical conditions.
Prognosis
Age spots are not harmful.
