What is tinea versicolor?
Tinea versicolor is a yeast infection caused by the overproduction of the malassezia (formerly pityrosporum) fungus.
Malassezia are saprophytic yeasts that live on the skin of most adults without causing any discomfort. However, in some individuals and in some circumstances, the fungus goes on to colonize large areas of skin, especially on the trunk.
What does tinea versicolor look like?
The overproduction of malassezia causes the formation of singular, round patches or larger areas of clustered patches on the skin. These scaly patches are light brown to pink in color and may cause mild itching.
The malassezia fungus is very sensitive to ultraviolet rays. When individuals with tinea versicolor are exposed to UV rays, the colonies of the fungus die, leaving behind a noticeable white patch. The infection becomes more noticeable against tanned skin, with many people only realizing they have tinea versicolor after sun exposure and therefore, paradoxically, after the fungal colony has died.
How to treat Tinea Versicolor
The yeast that causes Pityriasis Versicolor, Pityrosporum orbicularis or ovalis, is sensitive to antifungals and to Sulphur and Salicylic Acid, substances characterised by their long residence time in the skin following application.
As a cosmetic adjunct to the treatment of skin symptoms, the suggestion is to:
- Apply 2S Cream in the evening to the affected area for 7 consecutive evenings.
- Use Eudermic Cleansing Base, mild detergent for washing.
When the subject realises that he or she is predisposed to developing PV spots, he or she can use 2S Cream, one application every 15 days in the evening (twice a month) and discontinue when exposing himself or herself to the sun.
Avoid the use of moisturizing creams or other ointments, as they often promote the growth of the fungus due to their oiliness.
