In summer, when the temperature is high and the ultraviolet radiation is more intense, women wear sunscreen to protect their skin from ultraviolet rays. In the same way, the articles we usually use also have poor weather resistance in summer.

Under the strong sunlight, the weather resistance and yellowing resistance become very poor. After drying for a month or even a week, the color began to turn yellow and fade.
