What is pityriasis versicolor?

Pityriasis versicolor is known as damage caused by a fungus to the skin, the fungal infection can inhabit the patient’s skin and damage the natural pigmentation causing spots of a lighter or darker color than the patient’s skin tone.

Despite being a skin infection that is not dangerous or contagious, it can cause other emotional damage to the patient that is related to their self-confidence and self-esteem.

Hot and humid climates are favorable for the formation of these fungal lesions on the skin, yet there are a variety of effective treatments that can help restore the patient’s confidence.
