Age spots, also known as brown spots, liver spots and solar lentigines, are a common sign of aging. Flat, oval areas of pigmentation, age spots tend to appear on parts of the body, such as the face, hands, arms, shoulders and feet, that are exposed to the sun. Most common in people older than 40, they can be freckle-sized or more than a half-inch in length, and range in color from light brown to black. When age spots are grouped together, they appear even larger.
Causes of Age Spots
Although age spots are usually caused by accumulated exposure to the sun‘s ultraviolet (UV) light, they may also be the result of using tanning beds/lamps; trauma or injury; or genetic predisposition. People with light skin are more likely to develop age spots, as are those with a history of frequent sunburn or sun exposure.
Diagnosis of Age Spots
True age spots are harmless and do not require treatment. If what is thought to be an age spot appears irregular, however, a biopsy may be performed to ensure that it is not malignant. Spots with the following characteristics should be evaluated by a physician:
- Dark pigmentation
- Unusual combination of colors
- Rapidly increasing in size
In addition, spots that are itchy, red or sensitive, or that bleed, should be checked for malignancy.
Treatment Options for Age Spots
Although age spots are not medically dangerous, many people who develop them find them aesthetically unappealing. Treatments to remove age spots or make them less prominent include the following:
- IPL laser can help with age spots by targeting the excess melanin in the skin that causes these pigmented spots. The light energy from the IPL device is absorbed by the melanin in the age spots, causing them to break up and fade over time.
- A Hollywood Spectra Peel, also known as a Spectra Laser Peel or a Hollywood Laser Peel, is a non-invasive laser treatment that can help improve age spots and other pigmentation issues. The Spectra Peel targets pigmented areas of the skin, such as age spots, sun spots, and freckles, by breaking down the excess melanin that causes these discolorations.
- A chemical peel can help with age spots by exfoliating the top layers of the skin, which can reduce the appearance of pigmentation irregularities such as age spots. The peel works to break down and remove the damaged outer layers of skin, promoting cell turnover and revealing fresher, more evenly pigmented skin underneath. Over time, this can help to lighten and fade age spots, resulting in a more even complexion.
Each of these treatments may require more than one session to fully remove the pigmentation.
Prevention of Age Spots
To prevent age spots or keep them from worsening, avoiding prolonged sun exposure and regularly using a broad-spectrum (UVA and UVB) sunscreen is recommended. Wearing UV-blocking clothing and a broad-brimmed hat will provide additional protection.
