Freckles: Symptoms, Causes, Diagnosis & Treatments

Small sized brown coloured spots on the skin are known as freckles. They are especially present in those areas of the body that are exposed to the Sun, for example, the face. Though they may not give a good visual look, freckles are not harmful to the patient. The major factor that is responsible for the formation of freckles is the overproduction of melanin. This is the element that determines the pigmentation or colour or skin and hair. UV rays stimulation is the precise process that causes freckles.

Freckles are divided into two different categories

  • Ephelides: Lack of proper protection against the ultraviolet rays of the sun is the major cause of ephelides. These types of freckles are present on the face and back of the hands. It is also found in the parts above the waist. People with lighter tone are more prone to this category of freckles. The probability of such freckles is higher in the Asian and Caucasian people.
