UV, UVA, UVB, UVC, SPF, PA, PA+, broad-spectrum sunscreen, PPD, MPPD, MED, chemical sunscreen, physical sunscreen, waterproof sunscreen.What's the point?

UV: all kinds of sunscreens, hats, and clothing talk about UV protection, but UV isn't magic. It's Ultra Violet.Ultraviolet rays can cause damage to our skin. Besides tanning, sunburn and redness, they may also cause skin cancer.

SPF and PA are indices for UVA and UVB.Using products with these Numbers on them is like building a new defense tower to better protect our skin from these enemies.The higher the SPF and PA, the stronger the protection for our skin, in other words, the thicker the blood in the defense tower.

Broad-spectrum sunscreen is produced in accordance with the provisions, the amount of blood to meet certain requirements of various defense towers.These sunscreens have SPF 15 or higher and have passed UVA protection tests.Very reliable.

For some majors, MPPD and MED are respectively the minimum dose when our skin is exposed to UVA and UVB, which may lead to erythema and pigmentation on our skin.That is, the damage that dragon supersoldiers do to our defense tower during the experiment.

Chemical and physical sunscreens are simpler, like the concrete and steel that make up our towers.Chemical sunscreens work by absorbing converted uv rays, while physical sunscreens work by reflecting uv rays.

Waterproof sunscreens, as their name suggests, don't get washed away by water or sweat.Sunscreens such as amantinus fall into this category and are commonly used outside places such as the beach.

Look at the other answers, everyone has been to the topic recommended sunscreen, but in fact sunscreen is not suitable for all occasions.

For example, I like running, and I will go outside every morning to run for half an hour. Recently, the weather starts to heat up slowly, and the sunscreen will be uncomfortable to use. It is useless to apply less and the skin burden will be too heavy after applying enough, which will affect the skin's breathing and metabolism.Secondly, sunscreens with strong sun protection power tend to be thick and have a sense of presence. After sweating, sunscreens and sweat mix together, which will affect my mood to exercise.

What's more, sunscreen pollutes the ocean, which, combined with the problems we've been talking about, can be a recipe for self-sabotage.Therefore, when I go out for sports, I will choose hard sunscreen such as suntan clothes, which can prevent me from getting tanned and guarantee breathable comfort at the same time.

Bask in the requirement that my dress respect is taller, because not be all bask in dress to have bask in the effect, also not be all bask in dress to suit when motion to wear.In this regard, I also stepped on a lot of thunder, and explain to you when choosing sunscreen clothes need to consider what factors.

1. Wear resistance and comfort.Go jogging at ordinary times, the arm is ceaseless swing, the cloth that this brings about to bask in the cloth of the major area of sleeve child must have very strong wear-resisting degree, the demand that should withstand me to move for a long time, also want to maintain dress comfortable.

2. Air permeability and water resistance.Summer perspire is very normal thing, but prevent bask in dress with good permeability to be able to let the skin maintain a dry and bright condition, the sweat that gives also can be some less.In addition, water resistance is also very important, a sweat on the skin stick in the sunscreen clothes is not suitable for a long time to exercise.

3. Sun protection, of course, is the job of sunscreen clothing.Before you buy a sunscreen, be sure to do your homework to find out if its sunscreen technology works.
