Why does sister Dou’er “fake essence and false essence” call sun protection every day, but she is not as white as others? Every summer, sister Dou’er is ridiculed for “black and black”.
the main sunscreen is ultraviolet. Ultraviolet rays can accelerate the formation of skin melanin. If sun protection is not in place, it is easy to turn black and old. In serious cases, skin cancer and skin tumor may occur.
so the question is, you’ve used the most expensive sunscreen in the world, but it’s still black… How can you get the best results? What misunderstandings can we encounter in our daily life?
we usually commute in summer. Doctors suggest that SPF30 is enough, PA + + + sunscreen is enough, but if you want to stay outdoors for a long time or go to the seaside, you should choose spf50 +, PA + + + + +.

the advantages are strong coverage and good skin protection. The disadvantage is not delicate enough, thick and white, rough texture will make the skin feel oil stuffy, may also lead to acne.
pay attention! In addition to sunscreen on your face and arms, don’t forget your neck, back neck, back of your hand, ankles, and feet. These areas are also exposed to the sun. Remember to treat them fairly.
the amount of facial smearing is 2 mg per square centimeter. The amount of an adult’s face is about the size of a dollar coin. In terms of technique, we should pay attention not to rub, but to gently pat evenly. We should apply it every two or three hours, and apply it 30 minutes before going out.
in case of sunburn, you can take some measures on your own, such as ice compress with ice towel to relieve discomfort, and pay attention not to bathe in too hot water.

the UPF value of a qualified sunscreen clothing and hat should not be less than 15. The brim width of sun proof wide brim hat is recommended to be greater than 7 cm.
ordinary clothes also have a certain sun protection effect, and the clothing with dense stitching and dark color has better protection effect.

ultraviolet rays are divided into UVA, UVB and UVC. Among them, UVA has a strong penetration, which can pass through the glass and reflect to our skin on the ground. Therefore, indoor workers also need sun protection.
most men think that sunscreen is what women need to do. They think it’s strange for men to wear sunscreen or hold an umbrella.

sunscreens are time sensitive, not once a day. After going out, sweat will dilute the role of sunscreen, it is recommended that you make up every 2 or 3 hours is the best. Here’s the point! When you apply sunscreen, don’t apply it. It’s best to pat it evenly.
