Invisible spot ≠ no spot!! Is your stain still there?

Having a white face is the dream of every beauty lover. Unfortunately, the ideal is always plump, and the reality is always bony. Friends often leave messages in the background: what is the way to fade spots? Can skin care products lighten spots? Is it IQ tax? Don't worry. I'll talk about light spots today.

Spot, how did you get here?

A hot knowledge: the formation of spots is related to melanin. We can imagine the production and processing of melanin as a black factory, which is full of black heart hawkers who work 24 hours a day and work overtime.

Black heart vendors are diligent, just to produce more melanin.

The birth of melanin should go through three stages: production, transportation and deposition. For example, selling to the market goes through these three links: ① raw material production ② express packaging ③ market circulation. Without any of these links, melanin cannot be successfully generated.

In addition, various internal and external factors (such as heredity, endocrine disorder, lack of sleep, excessive pressure and body metabolic problems) are also the behind the scenes reasons that induce manufacturers to produce melanin in large quantities.

Invisible spot ≠ no spot

I've heard that the spots you see now actually grew out five years ago.

It's not Xiaoyan that frightens you. It takes time for melanin to be activated and finally expressed to the surface of the skin

Maybe 1-2 years, maybe 5 years, maybe 10 years, depending on your daily sunscreen and whitening work.

Invisible spots deep in the skin are similar to the cockroach theory - "seeing one means there may be 20000 at home".

Fortunately, now skin testing has enabled us to detect deep spots under the skin. You can see three indicators related to spots: spots, ultraviolet spots and brown spots. Ultraviolet spot → invisible spot in shallow layer, brown spot → invisible spot in deep layer.

With age, metabolism slows down, and these deep spots will increase. Therefore, the game with color spots is like a protracted battle. If the enemy is in the dark, whoever has the foresight to prevent early may be able to laugh longer.

Why do spots become obvious when you get older?

The post-90s and post-00s are saying that they are old. A very important reason is that the smooth, white and tender skin in the past suddenly grows some color spots at a certain age, and the whole skin color becomes dark. The fundamental reason is that it is inseparable from the synthesis and metabolism of melanin in the skin.

First of all, from the perspective of synthesis, the main reason for the increase of melanin is ultraviolet light. For example, ultraviolet rays will stimulate the skin to produce too many free radicals, which will trigger a series of signals to accelerate the synthesis of melanin, and finally lead to skin problems such as spots, darkness and even wrinkles.

Secondly, after skin aging, the ability to resist free radicals will decline and the metabolic rate will slow down, so melanin will slowly accumulate on the skin surface and form color spots that many people hate.
