The weather in Hainan makes the skin pores coarse.

The weather in Hainan is hot and sweaty. People who have been in Hainan are better, and their skin is used to it. If they come and go later, sweat glands suddenly secrete more sweat, which will lead to enlarged pores. Doing a good job of cleaning can effectively prevent the pores from deteriorating. The best solution is to take good care of them with skin care products, or it may slowly tighten the pores, but it is difficult to fully recover.
