Three sunscreen misunderstandings make you more and more black

Sun protection is needed when there is sunshine, no sun protection on cloudy days and indoors.

The naked eye of human beings can't see the pervasive ultraviolet rays. Although there is no direct sunlight on cloudy days and indoors, this does not mean that there is no ultraviolet light. 90% of the ultraviolet rays can penetrate the clouds and cause damage to the skin. In addition, UVA in the ultraviolet rays will refract into the room and cause the skin to darken. Even in the evening, there are strong ultraviolet rays in halogen lamps and fluorescent lamps in concerts, nightclubs, etc., so you should do sun protection work anytime, anywhere. Indoor protection only needs to choose SPF 15 or so, but outdoor activities must choose high-level sun protection to ensure that the skin is protected from ultraviolet rays.

You can use sunscreen without a sun umbrella or a hat.

Most MM will think that I have already supported the umbrella. Why do I have to wipe the sunscreen ? In fact, the umbrella hides more crises! The high quality umbrella can effectively block the ultraviolet rays, but no matter how effective it is, at best it can only Block direct UV rays. It can be said that there is no use for ultraviolet rays from refraction such as ground reflection or glass window. Experts say that wearing a large wide hat or umbrella with a 10 cm brim can only block about 70% of the light damage (equivalent to SPF 3 to 4), so choose a refreshing sunscreen suitable for the skin, with an umbrella, a hat, etc. External protection measures can really prevent sunburn and tanning.

Waterproof, sweat-proof sunscreen can be used without recoating

Even the best sunscreen products can not be sunscreen for more than ten hours. Because of the dilution of sweat and oil secreted by the human body, the sunscreen effect will gradually weaken. If you are playing at the seaside, you should pay more attention to the recoating. The so-called waterproof refers to the sunscreen function after 40% of the water in the water, after the water is evaporated, and then the sunscreen is still 40% after the water is applied. That is to say, the waterproof sunscreen product can only be limited to 40 minutes in the water twice, so it should be reapplied every one and a half hours. However, if you are in a cool environment without sun exposure, you can replenish it in 5-6 hours. >>>Foot care can also be beautiful
