Being in the sun for a long time, why does the skin turn black?

There are four seasons in a year, including vibrant spring, hot summer, cool autumn and snowy winter. However, the saddest thing is the hot summer day. Every summer, we experience three months of contact with the sun. Then, after a summer, I feel dark, so it will turn black after a long exposure in summer. Because of the strong sunshine and strong ultraviolet rays outside in summer, it is easy to turn black after a long exposure in summer.

Every summer, we will see that many people will take the best sun protection measures when they go out to play, such as wearing cool gloves, applying sunscreen, wearing a sun hat and using a sun umbrella to shade themselves. In fact, these measures have not had much effect. If exposed to the sun for a long time, it will turn black. Just doing these sun protection measures will be better than not doing them, and it will also play a certain role. At least you can rest assured.

It's really skinny to recall our childhood now. At that time, no matter how big the sun was and how dark it was, I went out to play when it was time, without taking any sun protection measures. In this way, even if I only play outside for a day or two in summer, I really feel a lot darker when I get home, such as my arms, face and neck, as long as it is exposed. This is because of summer.

Finally, if you really can't control yourself and want to go out to play in summer, I suggest you take good sun protection measures. As we all know, the sun in summer is very toxic. Some sensitive skin can't stand the sun's toxic exposure, and in severe cases, it may be allergic. If the skin is exposed to too much sun, it will be prone to aging and dullness. Once tanned, it may take a long time to return to normal, so it is necessary to take necessary sun protection measures.
