What is the reason for sudden spots on the face?

If spots suddenly appear on your face, you need to understand the causes. The most common one is that you don’t pay attention to sun protection, which causes skin pigmentation due to ultraviolet radiation. Genetic factors and external environmental pollution may also cause spots.

First, ultraviolet rays:

Ultraviolet rays are the main physiological stimulus for the proliferation of human melanocytes and increased skin pigmentation. The main cause of skin darkening is medium-wave ultraviolet rays. It can induce the proliferation of melanocytes and the production of melanin.

Second, genetics:

Studies have found that 30% to 47% of melasma has a family history. Researchers from the Institute of Dermatology of Anhui Medical University have found that the causative gene of freckles is in the region of bands 32 to 34 on the long arm of chromosome 4.

Third, environmental pollution:

Cities are becoming increasingly polluted due to various reasons. These pollutants cause micro-inflammations in the cells on our skin. This causes the cells in the skin to naturally secrete a substance called arachidonic acid to fight the inflammation. This arachidonic acid substance activates tyrosinase to a certain extent and accelerates the formation of melanin.

Fourth, trace elements in the body:

Through the detection of blood rheology, lipid peroxide levels, superoxide dismutase activity, whole blood glutathione peroxidase activity and analysis of zinc, copper, iron and magnesium in the serum of patients with chloasma, the researchers determined that there is a certain relationship between changes in trace elements and chloasma. Increased serum copper in the blood can increase its tyrosinase activity.

Fifth, oral medication:

Long-term oral administration of hibernation spirit, Lumina, spironolactone, birth control pills, etc. can also induce melanin.
