I have white spots on my face and arms that seem to spreading. they are noticeable since my skin is tanned. what can i do to avoid them?

Skin color changes: Can come from several different reasons. One could be a skin fungus which can spread and look like whiter spots than your normal skin. One remedy may be showering with selsum blue shampoo and let it sit on your skin for a couple if minutes. Another possibility is vitiligo (the michael jackson skin disease). This is a skin disorder where you start to lose the pigment cells called melanocytes.
