How many times is the best daily sun protection

Due to the gradual thinning of the ozone layer, the sun's ultraviolet rays are now very strong. Nowadays, when people go out with a sun umbrella, they are not concerned about whether they will get tanned, but more about whether they will get sunburned. Nowadays, even if you are fully armed for sun protection, you will still get tanned to some extent. So people usually consider how many times of sunscreen is better. The following mainly talks about multiples.

Generally, you can use a sunscreen with an SPF of 15 times in winter or when indoors; in spring and autumn, you can use a sunscreen with an SPF of 20 times or 25 times; in hot summer, you should use a sunscreen with an SPF of 30 times; in desert environments and when sunbathing, you should consider using a sunscreen with an SPF of 50 times or more.

Many of the current sunscreens are labeled with the usage environment, such as indoors, outdoors, in strong sunlight, etc. Can be used for reference.

I recommend this sunscreen. I have been using it.
