Sun: watch out for summer mushrooms!

Pityriasis versicolor is manifested by spots on the upper body.

Summer, the beach, the sun ... And the mushrooms! With sweating, some of them develop particularly, such as pityriasis versicolor. This benign mycosis can however be easily treated.

What is pityriasis versicolor?

Pityriasis versicolor is due to a yeast called Malassezia. It is naturally present on the surface of the skin but in some people, it can proliferate abnormally. Like many other fungi, pityriasis versicolor develops particularly in acidic environments.

In summer, with perspiration and acidic PH of the body, the skin becomes an ideal environment. Some factors can increase the risk of seeing it appear: clothes that do not let the skin breathe, hypertranspiration or immune system disorders. Teenagers are more likely to get the infection.

A cosmetic discomfort

In general, the fungus does not cause pain, although some people may feel some itching, as specified by the British National Health Service. The main discomfort associated with pityriasis versicolore is aesthetic: the mushroom leaves traces that can be brown, pink or red depending on the skin color. Small tasks grow progressively until they regroup and grow. They appear on the upper body: neck, arms and back.

How to heal?

To treat pityriasis versicolor, it is necessary to apply antifungal creams. In general, the infection disappears fairly quickly. After a few weeks, the skin is normally back to normal, but the risk of recurrence is high. In 90% of cases, people with the fungus will have a second infection within two years. For 10% of individuals, recurrences will be frequent over the long term. In this type of case, doctors suggest applying the creams preventively before the beginning of the summer.
