There are small white spots on the skin of my arms

Our Asian skin should be yellow, some with a light yellow tint. Some people are born with fair skin and are beautiful. However, if you find some small white dots on your skin color, you may have vitiligo. Vitiligo is caused by a disorder of melanocytes and is a congenital factor. It may also be related to other reasons.

White spot disease causes

Skin color is physiologically determined by a pigment in the skin called melanin, which is produced by special cells called melanocytes. This vitiligo may be a phenomenon of melanocyte degeneration and death. The exact cause is unknown, but there are four main possibilities:

(1) The peripheral nerves of the body's nervous system are abnormal, releasing toxic substances that destroy melanocytes.

(2) There is something wrong with the patient’s immune system, which produces antibodies against his own melanocytes, thus destroying his own melanocytes.

(III) Self-destruction theory: Melanocytes produce toxic substances during the process of pigment production, leading to self-destruction.

(iv) Congenital genetic defects make melanocytes vulnerable to damage.

(V) Other unknown factors.

Serious consequences

Typical vitiligo symptoms include milky white circular patches, and the course and severity of the disease vary from person to person. Generally speaking, vitiligo will be more obvious in people with darker skin, while people with fair skin will often notice white spots in the summer because of the obvious contrast of tanning. Patients with severe vitiligo may develop white spots all over their body, but it is always impossible to predict how severe the white spots of an individual patient will become in the future, and doctors cannot predict it either.

People with vitiligo often lose their pigment very quickly, but it is also possible for the condition to stop depigmenting suddenly. This process of discoloration stopping on its own and then starting to discolor again may occur repeatedly. Once formed, it is extremely rare for white spot lesions to restore their pigmentation on their own.
