Tinea versicolor, also known as sun spots, is a common fungal infection that is caused by an overgrowth of the yeast Malassezia furfur on the skin. The condition is often characterized by white or varicolored patches on the skin and is commonly found on the arms and legs.
Although the condition is not contagious, it can be unsightly and embarrassing for individuals who suffer from it. Sun spots are more likely to occur in warm and humid climates, and those who sweat excessively may also be at an increased risk.
