The reason why baby has white spots on eyebrows

Pityriasis alba

1. Cause : This disease, also known as simple pityriasis or dry pityriasis facialis, is a chronic skin disease of unknown cause.

2. Symptoms : It is common in children and young adults, and is more common in people with darker skin. Typical skin lesions are round or oval reddish spots with blurred edges, 0.5 to 2.0 cm or larger in diameter. After a few weeks, the pale red spots gradually turn into pale white spots, covered with a small amount of bran-like scales. The number of lesions varies, mainly on the face and occasionally on other parts of the body. No subjective symptoms, or there may be itching or burning sensation. The course of the disease varies in length, worsening in summer, but it can all resolve naturally.

Vitiligo

1. Cause : This disease is a depigmentation disease of the skin, mucous membranes and hair caused by a significant decrease or loss of melanocytes. The causes of vitiligo are quite complex, including autoimmune theory, melanocyte self-destruction theory, neurochemical factor theory, genetic factors, changes in trace elements and mental factors, microcirculation disorders, diet, emotions, tobacco and alcohol, drug stimulation, mechanical stimulation, surgery, trauma, and many other factors.

2. Symptoms : There is no significant difference between genders. The disease can occur in all age groups, but it is more common in adolescents. The skin lesions are depigmented spots, which are often milky white but can also be light pink, with a smooth surface and no rash.

Vitiligo secondary to inflammatory skin diseases

1. Cause : Long-term or frequent use of drugs such as thiourea, thiouracil, thyroxine, norepinephrine, etc. will also affect the synthesis and metabolism of melanin to a certain extent and induce white spots. In addition, direct contact can also induce it. For example, white spots occurring around the eyes are often caused by the use of eye drops.

2. Symptoms : It manifests as a special snail-like arrangement in various patterns, which can be distributed unilaterally or bilaterally. Biopsy shows normal or reduced melanocytes and a small number of melanosomes.
