The hot summer is the most afraid to go out, the hot sun is very uncomfortable, the beautiful girls are afraid to go out. So how can you do a good job in sunscreen?

How to judge sunscreen effect


When you buy a sun protection product, the most important thing you care about is its sun protection effect, which is called SPF (sun protection factor) and PA (sun protection index).


SPF is determined by the lowest dose of erythema on the skin. Redness of the skin after sun exposure, known medically as “erythema”, is the least severe reaction of the skin to sun exposure. The lowest dose of erythema is the shortest sun exposure time for erythema to appear on the skin. The higher the SPF, the longer the protection time. If you choose an SPF20 sunscreen, your safe exposure time is 15×20=300 minutes.


PA refers to the measure of effectiveness in preventing UVA. The defense effect is divided into three levels: PA+, PA++, and PA++. PA+ means effective, PA++ means quite effective, and PA+++ means very effective. Good bask in the product to want both give attention to, can resist UVB, also can block UVA. However, the higher the SPF value and PA protection level, the greater the irritation, and the more unsafe factors. Therefore, consumers should choose according to the sun exposure situation appropriate protection strength bask in the product.


Sunscreen Selection


For indoor work, it is recommended to choose SPF10, PA+ sunscreen cosmetics. If we go out everyday, we can choose SPF15 to SPF30. PA+ sunscreen products, 20 minutes before going out about the smear evenly, every 2-3 hours to wipe. For outdoor sports, choose spf30-50; PA+++ sunscreen products, every 2-3 hours to wipe.

Of course, the first is sunscreen umbrella, now the street girls hand an umbrella, but to choose an excellent sunscreen umbrella needs to do a good job oh


1.UPF value (UV protection factor) : The sun protection effect increases with UPF value. UPF30 has 95% UV filtering, which is enough for daily use, so the quality of sunscreen is guaranteed.


2.Umbrella fabric: non-adhesive umbrella fabric is thinner, but this kind of umbrella fabric through UV filtering technology, sunscreen ability is not inferior; The glue coated umbrella cloth has black glue, silver glue, etc., which is not easy to fall off, and has the effect of heat insulation while shading.


3.Color: Very hot fried vinyl is not necessarily the first choice! However, dark umbrellas are better at shading than light umbrellas. In addition, the reason why the price of color glue sunshade umbrella will be higher than that of vinyl sunshade, mainly because the production cost of color glue is higher, and more attention is paid to beauty.

So the hair after insolation is dry and yellow, make the hair fall out. Isn’t it very! Can be! Be afraid! ? That’s the doctor’s conclusion. I’m not being alarmist.


1.UPF value: the higher the value, the better the sun protection ability.


2.Fabric: the fabric is close and uniform, in order to prevent the sun in place with air permeability


3.Brim: wide brim cover area is larger, give consideration to neck, chin and other parts
