Pityriasis alba, also known as Pityriasis alba, is a common and benign skin condition that occurs mainly in children and adolescents aged 3 to 16 years. It is characterized by the presence of hypochromatic, i.e. lighter, patches on the skin, which are mainly located on the face, cheeks, neck, shoulders and upper limbs. Although the appearance of the white patches often causes concern for parents or patients, the condition is not contagious, nor is it associated with a serious health problem.

The exact cause of tinea versicolor has not been fully clarified. Experts believe that it is related to mild skin inflammation and is often associated with atopic dermatitis, dry skin and allergic diseases. Factors such as prolonged exposure to the sun, wind, cold and insufficient hydration of the skin seem to worsen the condition. In summer, the lesions become more visible, because the surrounding skin darkens, while the affected areas remain lighter.

Clinically, the condition usually begins with small red or pink plaques that show mild peeling. Over time, the redness subsides and white or hypochromatic spots with unclear boundaries remain. The lesions rarely cause itching or pain, which helps to differentiate them from other skin diseases, such as mycosis or vitiligo. Diagnosis is mainly made through clinical examination by a dermatologist and only in rare cases are additional tests required.

The treatment of white dandruff is mainly based on proper skin care. The daily use of moisturizing creams helps significantly in reducing dryness and peeling. At the same time, the use of sunscreen is particularly important, as it limits the strong contrast between the white spots and normal skin. In some cases, the dermatologist may recommend mild topical corticosteroids or anti-inflammatory creams for a short period of time.

Although the course of the disease can last months or even years, the prognosis is excellent, since most lesions gradually resolve without leaving scars or permanent skin changes.
