Is holding an umbrella in summer really effective in avoiding tanning?

Yes, holding an umbrella in summer is an effective way to avoid getting sunburned. Parasols can reduce direct exposure to ultraviolet rays, thereby reducing the production of melanin and achieving the effect of sun protection. In addition, parasols can also block infrared and visible light from the sun, which also promote melanin production, so blocking them can also help protect against the sun.

It's worth noting that different parasols have different sun protection effects, some can block UV rays completely, while others only block a portion of UV rays. In addition, if the parasol is not of good quality or has been used for too long, it may also have light transmission, resulting in a decrease in sun protection. Therefore, when choosing a parasol, it is necessary to choose a parasol with a high sun protection index and pay attention to replacing it in time.

In addition, even holding an umbrella cannot completely avoid being tanned, because the ultraviolet rays in the sun can also be reflected through the ground, walls, buildings, etc. Therefore, in addition to holding an umbrella, you should also try to avoid going out when the sun is strong, or wear long-sleeved clothes, hats, sunglasses and other sun protection measures when you go out.

No. There are two kinds of umbrellas, one is the umbrella we use to cover the rain on rainy days. There is also a parasol with UV protection on sunny days.

The sunlight reflected back from the car glass will also have strong ultraviolet rays, so in order to effectively avoid being tanned, the first needs to wear a parasol, and the second needs to apply the corresponding level of sunscreen.

Holding an umbrella in summer can effectively avoid getting tanned, and try to go out less at noon when the weather is hottest. The umbrella you buy must be a sunscreen paradise umbrella or something, and a cheap one doesn't have much effect.

Of course it's true, the ultraviolet penetration in the sunlight is very weak, and the umbrella can completely block it, so it can avoid being tanned.

Of course, this umbrella is an umbrella with anti-ultraviolet function, avoiding direct contact with ultraviolet rays, and naturally avoiding the fate of being tanned.

Summer shirts can not effectively avoid being tanned, depending on what material you use umbrella, the kind of umbrella with sunscreen function can play an effective suntan function.

In principle, this is true, but it has something to do with the quality of the umbrella, and UV-blocking umbrellas have certain advantages over ordinary umbrellas in terms of preventing sunburn.

Hello, Know Me Cosmeceutical Skin Consultant is happy to help you.

When you go out in summer, in addition to playing an umbrella, you also have to wear sunscreen to protect yourself from the sun. Generally, sunscreen should be applied about 20 minutes before going out, because sunscreen does not have the effect of sun protection when applied to the skin, and it needs to give the skin time to absorb. If it is a purely physical sunscreen, it does not need to be applied in advance, because it acts directly on the surface of the skin and will not be collected by the skin.

Sunscreen doesn't last all day, so reapply it when you're sweating a lot or you're outdoors for a long time. It is advisable to avoid sunny hours between 12 noon and 2 p.m., as the ultraviolet rays of the sun are the most damaging during this time. Dear, I hope it can help you.

Wearing an umbrella that is not UV protection in the summer can prevent tanning. Ways to prevent tanning:

1. Apply sunscreen.

In summer, the sun becomes scorching, and sunscreen is an essential sunscreen, so you should apply sunscreen thirty minutes before going out, so as to achieve a good sun protection effect.

2. Reapply sunscreen in time.

Sunscreen can form a protective film for **, but this protective film can not maintain a day of sunscreen, the general sunscreen effect is maintained at 3-6 hours, so it is necessary to make up the sunscreen in time, so as to prevent tanning.

3. Use a parasol when you go out.

In this way, the umbrella should be a must-have for girls in their summer bags, and it can play a role in shading and ultraviolet protection outdoors to avoid direct sunlight from causing damage.

Some umbrellas don't have the function of blocking ultraviolet rays at all, so tanning is a normal thing.

Here's how to protect yourself from the sun in summer:

1. Start by applying sunscreen. Sunscreen is especially important, and you should wear it half an hour after you go outside. And it should be applied evenly, so that it will be better to go out.

2. Then go out with an umbrella, the kind of sunscreen.

3. Then when you go out, it is best to avoid ten o'clock to two o'clock in the afternoon, because this point is the time when the ultraviolet rays are highest.

4. Soak some water with lemon at night to drink, remember that lemons cannot be drunk during the day, because lemons absorb light during the day and will become black when drunk.

5. Then it is very important to make a **, if you are very exposed during the day, you need to make an aloe vera**, and the repair after the sun is super good.

What you need to play an umbrella in summer is a special sun umbrella, and ordinary umbrellas have no sunscreen effect.

How to choose a sun umbrella:

1. Sunscreen protection index (UV resistance index).

First of all, look at the fabric, and be sure to pay attention to the choice of brand. Regular brand umbrellas are required by the state to indicate the corresponding sun protection index on each umbrella. At present, domestic and foreign standards generally use UPF value, that is, the value of ultraviolet protection coefficient for the ultraviolet protection performance of textiles.

The UPF value is the ratio of the average amount of UV radiation to the unprotected**, and the higher the UPF value, the better the UV protection. This index will be marked on the products of regular manufacturers.

2. Light transmittance.

Transmittance is the percentage of the luminous flux that passes through a transparent or translucent body to its incident luminous flux. The ultraviolet rays in sunlight are different from ordinary light wavelengths, and ultraviolet rays are not visible, and the light transmittance mainly takes into account the degree of adaptation of the eyes. The UV protection index is invisible and is an important indicator for protecting health.

It's not like an umbrella can definitely prevent tanning, dear, sometimes it is necessary to apply some sunscreen. Some people are naturally prone to tanning, and some people are not afraid of tanning. I belong to the same former, and it may also be caused by the fact that ** is too thin and has a weak ability to resist ultraviolet rays, but I usually apply water to the baby for sunscreen, and I generally don't go out to dry outdoors if it's okay.

Just try to avoid sun exposure. Coefficients below SPF 30 are worth considering.

Is your umbrella fully protected There are two kinds of ultraviolet rays, UVA and UVB, both of which are prevented so that they will not be black, my umbrella is coated with a reflective sunscreen layer on the sunny side of the umbrella, and the umbrella is black sunscreen under the umbrella, so that it can be fully protected and the umbrella should be a little larger, so that there is more place to cover.

Wearing an umbrella is only to prevent direct sunlight, and the reflection of the surrounding buildings, including the ground, will also make you black, so it is not enough to wear an umbrella alone, either wear long sleeves to protect it, or wear sunscreen, and go back at night to whiten.

I use an umbrella almost every time I go out, why am I still tanned, and sometimes I touch sunscreen, but not an umbrella can't block all ultraviolet rays Sunscreen is the same Even if I wear sunscreen and an umbrella, I can't.

It means that your sun is really too strong, or your sun umbrella has too poor sun protection.

Is your sunscreen not good, sunscreen is applied 15 minutes before going out, and the ultraviolet rays are strong to make up the sunscreen once every 4 hours.

Then reduce going out, and it is best to choose the time to go out in the morning and evening. Put on a sun hat and a shawl to protect against this line.

The umbrella should be dark-colored, and there should be no silver inner layer; Apply sunscreen the size of a grape, and try to choose waterproof ones; Hydrate your skin before going out, and hydrate ...... as soon as you returnEat more tomatoes.

Try to go out to the sun as little as possible. For example, go out when the sun is not so strong. Or switch to a sunscreen with a higher SPF. Of course, the prerequisite is that you don't have allergies.

The scorching summer is about to pass, and the autumn tiger is coming again, and the ultraviolet rays are still strong. For beauty lovers, sun protection is essential when going out. However, some people still turn black despite diligently applying sunscreen and parasols every day, so what misunderstandings may they have walked into?

Myth 1: Irregular sunscreen

Although you wear sunscreen every day, but the quality of the sunscreen itself is not up to standard, it is obvious that it will not have a good sunscreen effect. Therefore, when choosing sunscreen, you must choose products produced by regular manufacturers, and the sunscreen spectrum produced by the manufacturer must be complete enough, so as to be able to effectively protect from the sun.

Myth 2: Apply before going out

Although we often say, "Always remember to wear sunscreen before you go out." "But you can't really put sunscreen on before you go out.

Because for it to work, it takes about 20 minutes for the film to form. Therefore, if you apply it before you go out, it will not be able to protect you from the sun when you go out before the film is formed.

Myth 3: Apply only once a day

This misunderstanding must have been avoided by many people, but it is still necessary to always remember and strictly implement it in order to be insured. Sunscreen is not something that can be applied once in the morning and you will not be afraid of the sun all day, it needs to be reapplied every two hours, and the dosage should be more than less, so that you can really not be afraid of the sun all day long.

Myth 4: You don't need to paint it on cloudy days

Our sunscreens protect against UV rays, not the sun. During cloudy days, even though the sun is not shining in the sky, ultraviolet rays can penetrate the clouds, which can also tan people. As long as the meteorological department shows that the UV rays are greater than or equal to 3, then it is necessary to wear sunscreen.

Sunscreen is a long-term and long-lasting work, in order to have a white and healthy **, sunscreen work must not be sloppy.

In this case, it is generally not prepared in advance, and if you suddenly apply it when you go out, it has not formed a good protective measure, and it will not be effective, so you must apply it in advance.

Sunscreen is not the best thing to do when you go out, and it should be applied half an hour before you go out. And you have to apply it every two or three hours.

Most people think that sunscreen can last for a day with one application, but in fact, sunscreen is time-lasting, and we need to make up for sunscreen every three to four hours.

The sunscreen itself does not protect against tan, and if your sunscreen itself does not have the ability to protect against tan, then you are not negotiable about natural tanning.

It may be that the quality of the sunscreen used is not good, or the sun protection index is not enough, and it cannot withstand the damage of ultraviolet rays.

Maybe the sunscreen you're using doesn't have enough SPF, or maybe your parasol doesn't have UV protection.

Sunscreen and umbrellas are only part of the equation, but the most important thing is to repair them after the sun.

First of all, it's probably because sunscreen is too cheap to be effective.

Either your sunscreen isn't very good, or you're just about to put it on when you're out the door. And if you only apply it once a day, it won't be effective!
