Ultraviolet rays are the main killer of skin aging, which can make skin texture chaotic, blood circulation poor and melanin accumulate, thus making skin dark yellow, so we should pay attention to blocking ultraviolet rays no matter what season.

Be sure to protect yourself from the sun when you go out. Even in autumn and winter, as long as there is the sun, you should apply sunscreen on the exposed parts, choose SPF index according to the strength of the sun, and bring umbrellas in summer to try to be fully protected from the sun.
