Solar lentigines, commonly known as sun spots or age spots, are harmless patches of darkened skin that result from exposure to ultraviolet (UV) radiation. This exposure leads to local proliferation of melanocytes, the cells responsible for producing melanin, the pigment that gives color to our skin, hair, and eyes.
A solar lentigo is a flat or slightly raised brown lesion with a clearly defined edge. Unlike a true freckle, which is generally uniform in color, a lentigo can range from tan to dark brown. These spots are often found on chronically sun-exposed sites such as hands, face, lower legs, and may also follow sunburn.
Sometimes referred to as liver spots due to their brownish hue, solar lentigines are not indicative of liver disease or dysfunction. They are simply a sign of skin’s response to sun damage over time.
1. What are solar lentigines?
Solar lentigines, also known as sun spots or age spots, are harmless patches of darkened skin that result from exposure to ultraviolet (UV) radiation.
2. How can I prevent solar lentigines?
Limiting sun exposure, using sunscreen, and wearing protective clothing can help prevent solar lentigines.
3. What treatment options are available for solar lentigines?
Treatments include cryotherapy, laser therapy, pulsed light, and chemical peels. Consult with a dermatologist to choose the best option for you.
4. Are solar lentigines dangerous?
No, solar lentigines are not harmful. However, any new or changing spots on the skin should be evaluated by a dermatologist to rule out skin cancer.
5. Can solar lentigines be completely removed?
While treatments can help reduce the appearance of sun spots, they might not completely remove them. Also, new ones can form if the skin is exposed to more sun damage.
6. What is the CryoPen procedure?
CryoPen is a form of cryotherapy that uses extreme cold to destroy abnormal tissue. It’s an effective treatment for solar lentigines.
7. How does the CryoPen procedure work?
The CryoPen device is applied to each lentigo, emitting a jet of nitrous oxide that freezes and destroys the discolored cells.
8. What are the aftercare instructions for the Cryopen procedure?
Patients should avoid strenuous activity for 24 hours following the procedure, avoid picking or scratching at the area, and keep it clean and dry to aid in the healing process. Sun protection is also important in the weeks following the procedure.
