Answer

Malassezia organisms can be found on the skin in 75-98% of healthy people. These organisms are part of the normal skin florae of many individuals who do not have signs or symptoms of folliculitis or other disease. Colonization by M furfur begins soon after birth, and the peak presence of the yeasts occurs in late adolescence and early adult life, coinciding with increasing activity of sebaceous glands and concentration of lipids in the skin.
