The skin is made up of many layers that help it protect the body from various diseases and infections. The color of the skin is determined by the quantity of a particular pigment that is found in the skin. This pigment is known as melanin. Darker skinned individuals have a higher amount of melanin in their skin than lighter skinned individuals. In some cases, melanin distribution may be uneven leading to darker or lighter patches of skin.
White spots on legs can be a result of a few different conditions. It is important that the patient is aware of the underlying condition that is causing the white skin spots. In some cases, the condition is caused by an infection or infestation while in other cases it is caused by a deficiency of melanin. Vitiligo is a disease that affects the skin's ability to generate melanin. This results in patches of skin that lose their color. Gradually, the skin patches become larger and larger. An individual with serious vitiligo will change his or her skin color to a light shade of pink. Vitiligo is a condition that cannot be cured. Certain creams and steroid treatments can be used to help reduce the spread or the speed of the spread of this condition. The condition, however, cannot be reversed. It must be noted that patients suffering from vitiligo may not experience any itching or discomfort associated with the change in their skin color.
White skin spots may also be caused by a fungal infection. Fungi are present on and within the human body in small quantities. Regular washing and good hygiene usually ensures that fungi do not have the opportunity to multiply. However, an individual may suffer from skin fungus that causes the skin to appear white in patches. This type of problem may also cause itching and irritation on the skin. The treatment of this kind of problem is based on the diagnosis of the condition. In some cases, samples of the infected area may be scraped off for testing to determine the exact type of fungi. The patient will then be given topical and oral treatments to deal with the condition. In some cases, the skin may lose its pigment due to underexposure to the sun. Individuals suffering from this type of problem may spend time in the sun as this helps to nourish the skin by aiding the production of vitamin D.
