What reason is feeling a lot of melanin on the face

First: if you want to know the reasons that affect the formation of melanin, you must understand how melanin is synthesized. Tyrosine tyrosinase reaction is the key reaction of melanin synthesis, so if this reaction is disturbed. Then this reaction can not be normal, it can not be normal synthesis of melanin, and synthesis of some other substances.

Second: another reason that affects the synthesis of melanin is the melanosome. The transport function of the black body is very important. We all know that the circulation in the body is regular. Once it is broken, the consequences are unimaginable. Therefore, if the transport of the black body is not smooth, the black body will stay in the melanocytes, and then the function of the melanocytes will decline.

Third: the last reason that affects the formation of melanin is ultraviolet light. This is a kind of external factors, the impact of ultraviolet on the human body, I believe we are not unfamiliar. In general, ultraviolet can enhance the tyrosinase activity in melanocytes, then increase the number of melanocytes, and then the movement speed of melanosomes will be accelerated. So it is necessary to prevent the interference of ultraviolet.

matters needing attention

Too much melanin accumulation or too little melanin production is not a good thing for the human body, so people should understand the reasons that affect the formation of melanin, to avoid UV damage, usually take a sunshade.
