the white spots on your face

the white spots on the face after exercise? Not a fungus infection. I found out from my best friend (google) on what they are and the treatment.

Definition of Pityriasis

Pityriasis is one of any of a number of skin diseases that have in common lesions that resemble dandruff-like scales without obvious signs of inflammation.

Types of pityriasis include: pityriasis alba (also called pityriasis streptogenes, pityriasis simplex, erythema streptogenes); pityriasis rosea; pityriasis rubra pilaris; and pityriasis versicolor (tinea versicolor).

Description of PityriasisPityriasis alba

This is characterized by hypopigmented, round to oval, scaling patches on the face, upper arms, neck, or shoulders. The patches vary in size, usually being a few centimeters in diameter. The color is white or light pink. The scales are fine and adherent.

Usually, the patches are sharply demarcated; the edges may be erythematous and slightly elevated. As a rule, pityriasis is asymptomatic. However, there may be mild pruritis. The disease occurs chiefly in children and teenagers.

The cause is unknown. Excessively dry skin following exposure to strong sunlight appears to be contributory. Efforts to find an infectious agent - either bacterial, viral, or fungal - have been unsuccessful.

Treatment of Pityriasis

Highly useful are 0.5% hydrocortisone and 1% crude coal tar in a cream base (Zetone cream), half-strength Pragmatar ointment, Lac-Hydrin, 2% Zetar in Cordran cream, or 1% Vioform cream. The prognosis is good and there is usually spontaneous healing within several months to a few years.
