Chapter 3 Test Your Sunscreen Quotient
As the saying goes, "the face is white and pretty", most oriental women regard themselves as beautiful.Whether the skin is fair and attractive is closely related to the number of melanocytes in the skin.Because ultraviolet rays can activate melanin in the human body, color spots will appear.Sun protection is indeed a compulsory course for ladies who love beauty.

Usually, you put on sunscreen and put on a sunshade, why does your skin still turn dark?Compare the simple test below to find out how high your sun protection quotient is!

1. Are you born with the "capital" to bask in the sun?
2. As long as you use an umbrella when you go out, is there no risk of sunburn?

3. When the sun is strong, do you feel that wearing white clothes is both cool and sun-proof?

4. As long as you wear sunscreen when you go out, do you need to reapply it at any time?

5. Is the sun protection factor of sunscreen products as high as possible?
6. Can the sunscreen effect of sunscreen products be superimposed?
7. Now many girls like wheat-colored skin. Do you also think that a little tan would be healthier?
8. Do you no longer need to apply sunscreen if your skin is already tanned?

9. After sunburn, should you apply plaster immediately?

10. If you sit in an office and work every day, do you not need to take sun protection measures?
11. When you get home at night, do you still need to do your homework on sun protection?
answer:

1. If the human body has been exposed to the sun for 5000 hours, skin cancer may occur.This sunshine time not only refers to the exposure to the sun in summer, but also includes the time when the human body is in contact with the sun every day.Therefore, the more sun exposure, the greater the risk factor of skin exposure to the sun.

2. 50% of the ultraviolet rays in the sun will pass through the parasol.Parasols only block the burning UVB rays, but UVB rays penetrate without difficulty.

3. White clothes can only reflect the heat of the sun, but cannot block ultraviolet rays, while black, red, purple, navy blue cotton clothes are good choices.

4. The efficacy of sunscreen products has a certain time limit, and everything will be fine after just one wipe.During outdoor activities, in order to maintain the anti-ultraviolet effect, sunscreen products must be reapplied every 2 to 3 hours.After swimming, you should wipe off the water at any time and reapply.

5. For daily whitening and maintenance, you can choose sunscreen products with an SPF value of 8 to 15, and you don’t need too high a sun protection factor.Only when you are engaged in outdoor activities such as swimming and playing ball or in the hot summer, you should use sunscreen products with an SPF value above 15 to resist the damage of ultraviolet rays to the skin.If you blindly pursue a high SPF, it will cause unnecessary burden on the skin.

6. When these beauty products are rubbed more than three layers one after another, no matter how many layers are added, its coefficients will not be added or multiplied.Although the SPF value cannot be multiplied, but because each layer is applied thickly, it will still have a certain sunscreen effect.If the sunscreen product is applied thickly, you should choose a refreshing lotion; if you apply it thinly, you must choose a high-factor sunscreen product.

7. When the human body is irradiated by ultraviolet rays, more melanin will be formed in the basal layer of the skin, which is a self-protection mechanism of the skin.Darkening your skin tone is a form of protection, but with an SPF of only 2, it doesn't help much.Any degree of tanning increases the chances of skin cancer and is the cause of skin aging and wrinkles, so tanning is not good for the skin.

8. The skin turns brownish yellow after sun exposure, indicating that the skin has entered a state of self-protection, and the production of melanin is the performance of the skin's self-protection.But melanin can only absorb medium-wave ultraviolet rays, so that the skin is no longer damaged by it, but it is powerless to long-wave ultraviolet rays.

9. Do not apply plaster after the skin is sunburned, otherwise the high fever will not be dissipated, but will cause further damage; do not apply thick skin cream, otherwise it will affect the immune and repairing functions of the skin.

10. The exterior walls and glass windows of buildings cannot isolate ultraviolet rays.Even if you sit in the office every day and don't go out, you should apply SPF15 sunscreen and keep the curtains closed.

11. When you get home, you need to use a facial mask for moisturizing and whitening, and apply skin care products all over your body after taking a shower, because there are also ultraviolet rays at home, and the light from lights, TVs, and computers will make the skin grow spots.

Beauty tips: After sunburn, you should apply cold compresses immediately, and apply cold compresses every once in a while, so as to dissipate the deep heat energy and reduce the thermal reaction of the skin.You can also use aloe vera to help cool the skin.
