What are age spots?

Age spots (also called solar lentigo or liver spots) are collections of pigment caused by overexposure to the sun. They also sometimes result from bruises that leave blood pigments behind.

They are most common in people over age 55. Age spots commonly appear on the hands but can occur almost anywhere, especially areas that are more exposed to the sun than others such as the face, back, arms, feet, and shoulders.

When most of us see a skin blemish, we want to remove it.  However, the first step is to make sure it isn’t skin cancer.  Early stages can masquerade as innocent-looking age spots. If a spot enlarges, thickens, changes color, bleeds, or itches, see your doctor.

Whether we call them age spots, sun spots, or liver spots, they aren’t freckles.  Age spots are the result of excess pigment deposited in the skin during years of sun exposure.  If you absorbed a lot of direct sun over the years, you built up what are technically known as lentigines.  Lentigines are also age spots. None of us likes to look older, so many people with age spots look for ways to remove them.

For professional treatment, see a dermatologist.  They specialize in skin care.

Medical treatment

Retin-A
It is a topical application of tretinoin, a vitamin A acid.  It was developed by Albert Kligman, MD, Ph.D., professor of dermatology at the U of Pennsylvania in Philadelphia.  It eliminates fine wrinkles, blemishes and age spots by stimulating cell turnover in a metabolic process that Dr. Kligman acknowledges is still not entirely understood.

While it’s supposed to be available only by prescription you can buy it online.  However, we recommend that if you use this medical treatment, you work with a dermatologist to find a dosage that’s right for you.

Retin-A comes in a cream that is applied topically. The area begins to peel and after a few months the spot should diminish and could disappear.  It continually helps shed the outermost, dead layer of skin, so it can not only eliminate existing spots but can also prevent new spots from occurring.

The downside is the fact this area of new skin, which was previously sheltered from the elements, becomes exposed. That’s why a frequent side effect is dry, sun-sensitive skin that can be irritated and scaly.

Potential negative side affects from too much Retin-A are the reason why the product is only available by prescription through dermatologists.

We understand both of the above side effects typically diminish with time.  However, careful care is required while using the product.  Also be aware that you will need to use a moisturizer and sunscreen once you start using it.
