It takes a lot of time in the sun to get darker and darker. But you never know why this is so, rest assured that science has a reasonable explanation. Schalka, a dermatologist at Brazilian medical institutions, said: "Tanning is one of the defense mechanisms of the skin against the sun's radiation."
According to Schalka, exposure to solar radiation can cause DNA damage to our skin cells. This damage can cause problems, such as skin cancer. Therefore, our body has developed a substance called melanin in the skin that is oxidized to resist long-time solar radiation. This prevents damage to the skin due to radiation damage, giving it a deeper color, commonly known as tan. Schalka still said that about 70% of skin aging is caused by sunlight. Protect her. This is a way to make you younger.
