Pityriasis alba causes acne-like breakouts on the face.
White pityriasis causing facial acne may be due to excessive oil production, bacterial infection, skin irritation, and inflammation. Treatment should be based on the specific condition. Details are as follows:
1. Excessive Oil Production
White pityriasis is associated with excessive sebum on the skin. Overproduction of oil can lead to clogged hair follicles and bacterial growth, thereby triggering the formation of acne. When white pityriasis occurs on the face, excess oil may promote the development of acne.
2. Bacterial Infection
The areas affected by seborrheic dermatitis may provide an environment conducive to bacterial growth. These bacteria can provoke inflammatory responses and contribute to acne formation. Bacterial infection is a potential cause of acne on the faces of patients with white pityriasis.
3. Skin Irritation and Inflammation
White pityriasis can cause inflammatory symptoms such as redness, itching, and flaking. The inflammatory response may increase skin sensitivity and potentially trigger acne development. Irritants such as cosmetics, facial cleansers, or environmental factors may exacerbate the appearance of acne.
In addition to the above causes, acne-like lesions might also result from sebaceous cysts, lipomas, fibromas, or other conditions. Avoid scratching with hands and maintain cleanliness of the affected area.
