Hyperpigmentation on the legs can be caused by a number of factors.
Dark spots can be caused by sun exposure, diabetes, and other health problems.
The course of treatment is individual and depends on the underlying cause.
This symptom is familiar to many people - basically, the cause of dark spots is that a much larger amount of melanin is produced in this area of the skin. It is melanin that gives your skin its color; the more melanin, the darker the skin tone.
In a large percentage of clinical cases, dark spots on the legs are not dangerous, but it never hurts to be careful and it is better to check with a dermatologist.
However, in the case of these symptoms, you should immediately consult a doctor:
- The spots are raised/convex from the skin;
- The mole has changed in appearance;
- You have dark spots on your finger, nose, vagina, anus, palm, mouth;
- Other types of and unusual injuries.
