What happens during the disease - pityriasis alba
Pityriasis alba is a common skin condition characterized by pale, scaly patches on the face, neck, and upper arms. it is caused by a disruption in the normal skin barrier, resulting in an increased permeability of the skin to environmental stimuli. this increased permeability leads to a decrease in the natural oils and lipids that help protect the skin, resulting in dryness, flaking, and pale patches. additionally, the disruption of the skin barrier can lead to an overgrowth of certain types of bacteria, resulting in inflammation and further skin discoloration.
Pityriasis alba - Prevention
Pityriasis alba can be prevented by avoiding excessive sun exposure, using sunscreen with spf 30 or higher when outside, and moisturizing the skin regularly. additionally, it is important to maintain good general hygiene and a healthy diet.
