What is the best temperature for sun protection in summer? The weather is about 37 degrees.

37 degrees, just use 30 times the sunscreen.

Ideally, sunscreen should be used after cleansing and before putting on makeup to ensure that it is close to skin cells that need protection. But in practice, basically, after the daily skin care steps, you can apply sunscreen and then make up daily. But sunscreen, like ordinary skin care products, takes a certain time to be absorbed by the skin, so sunscreen should be applied 10~20 minutes before going out.

At the same time, it should be noted that the duration of the effect depends on the SPF or PA value of the product.
