" White skin spots are irregular patches marked by lack of color or pigmentation, which can appear in different parts of the body. Skin damage can cause an interruption in the production of melanin, the skin pigment produced by specialized cells in the skin called melanocytes, resulting in white spots on the skin. See the treatment section at the bottom of this page for Dermatologist administered and home treatment options."
Another common skin condition that causes white skin spots is Pityriasis alba, which usually affects children and adolescents. The cause is unknown, but it is associated with eczema, a chronic skin condition characterized by itchy, scaly, white patches of skin. It is also seen in people that suffer from allergies or asthma.

This leads to the appearance of reddish-tan discoloration and white skin spots. This skin condition is common among adolescent boys and young men and occurs in hot climates.
Other conditions that can lead to white skin patches are nevus depigmentosus, idiopathic guttate hypomelanosis, and halo moles.
