Symptoms
The emergence of black spots on the skin is the only symptom. They don't itch and aren't painful.
Diagnosis
Age spots are self-diagnosable based on their appearance. Contact your doctor if you are concerned about changes in your skin. He or she can conduct testing to rule out the presence of other diseases.
Expected Timeframe
Most age spots fade with time, but because the skin has been injured, they are unlikely to remove completely.
Prevention
You can reduce the risk of age spots by reducing your sun exposure. Sun exposure before the age of 20 is the most important element in determining the appearance of your skin later in life. Limiting your sun exposure will help prevent age spots from expanding or deepening if you already have them.
Wear long-sleeved shirts, slacks, and a hat to protect your skin from the sun. If you'll be outside for more than a few minutes, wear sunscreen. 10am to 3pm is the best time to avoid the sun because the sun's rays are at their strongest at this time. This is the best time to stay out of the sun.
Treatment
Age spots do not require treatment. A dermatologist may be able to prescribe medicine to lighten the spots or provide another sort of treatment if you want aesthetic treatment.
When to consult a doctor?
Contact your doctor if you are concerned about changes in your skin. He can rule out cancer and other underlying medical issues.
Prognosis
Age spots aren't dangerous.
