Do you need sun protection in winter Why don t you tan too

Although the ultraviolet rays are not as strong as in summer, they also have ultraviolet rays, so sunscreen is to take a bath all year round to protect from the sun, and in winter, you can use sunscreen products with a slightly lower sun protection index.

Not protecting yourself from the sun can really lead to tanning. When exposed to sunlight and nuclei, UVA rays (especially UVA and UVB) penetrate the surface layer and cause damage. UVA can cause tanning and aging, while UVB can cause sunburn.

Prolonged exposure to sunlight produces more melanin to absorb UV rays, thus protecting cells from UV damage. This reaction manifests itself as a darkening. Therefore, not protecting yourself from the sun can indeed lead to a tan.

In order to maintain ** health, the following measures are recommended:

1.Use sunscreen: Choose a sunscreen with an adequate sun protection factor (SPF) to disrupt and make sure to reapply regularly during outdoor activities.

2.Avoid the time when the sun is at its strongest: Try to avoid the sun's heaviest hours between 10 a.m. and 4 p.m.

3.Wear sun-protective clothing: Choose long-sleeved clothing, long pants and a wide-brimmed hat to protect** from direct sunlight.

4.Find shade: When outdoors, try to rest in the shade and avoid prolonged exposure to the sun.

With these measures, you can reduce your risk of tanning and sunburn while protecting** your health.

Yes, sunscreen is recommended.

For the young lady who loves beauty, she must do a good job of sun protection, especially pay attention to applying sunscreen, but some friends feel that it doesn't matter if you wipe sunscreen or not, in fact, there are many harms if you don't wear sunscreen. So what are the dangers of not wearing sunscreen? Why does sunscreen turn darker when I wear it?

Here is a detailed answer to this question.

The hazards of not rubbing sunscreen are these:

1. It may cause sunburn, and the skin will appear red spots, peeling, burning, itching and other discomforts after the skin is exposed to the sun.

2. It will cause skin tanning, because the melanocytes in the skin will accelerate their secretion after being irradiated by ultraviolet rays, and they will become dark.

3. Cause aging, collagen and elastin in the decomposition and degeneration, thereby accelerating the aging of the company.

There are several reasons why sunscreen turns darker:

1. It may be that the sunscreen is not long enough, you must know that after the sunscreen is applied, no matter how much the sunscreen index is, it needs to be reapplied, if you don't reapply, it is easy to tan, because no sunscreen can resist ultraviolet rays all day long, and it is necessary to reapply properly to bring a good sunscreen effect and avoid darkening.

2. Improper selection of sunscreen, sunscreen is a job to be done all year round, but when you choose sunscreen, you should choose according to the actual situation, for example, if you have been exposed to the air, you need to choose a sunscreen with a high sun protection index, so as to protect the skin. If you choose a sunscreen with a low index, you will not achieve a good sunscreen effect, and your skin will darken.

Everyone should pay attention to the correct application of sunscreen when applying sunscreen, so as to bring good results.

Wearing sunscreen doesn't mean you can't tan. The effectiveness of sun protection is related to the choice of sunscreen, the use of sunscreen, and the repair after the sun. The level of SPF is directly related to the effectiveness of sun protection, but it is not necessarily that the higher the SPF, the better.

It is best to clean with a makeup remover to avoid clogging pores and causing acne.

Doing enough sun protection with sunscreen or black, another point could be that sun repair isn't doing well! If you've been staying indoors, you generally don't need to do special sun repair, moisturize 2-3 times a week**; If you've experienced the sun, you have to do a sun repair, in fact, it's not that hard, is to apply a moisturizing repair** or aloe vera gel, followed by a whitening serum and moisturizing lotion! Once you sweat, basically the sunscreen will also be lost with the loss of sweat, so the end result will definitely not leave sunscreen on the face, so we should replenish sunscreen in time when exercising outdoors.

If you go out and apply it temporarily, the sunscreen has not yet formed a film and will not achieve the desired effect, and you will still tan in the sun, and you generally need to apply it 20 to 30 minutes before you go out. Then the dose is not enough. When sunscreen is applied too thinly, the sunscreen effect will be relatively reduced, and it will also be affected by ultraviolet rays and darken.

The outdoor ultraviolet rays are too strong, and it is especially easy to sweat outside, so it is easy for the sunscreen to disappear, so the face is not protected in the later stage, and it will naturally tan.

If you don't want to get a tan, it's best to apply sunscreen half an hour before you go outside. Of course, sunscreen can give a sense of boredom. Therefore, Sister Persimmon recommends not to apply it at home, so it is best to apply it half an hour before, which will not affect the comfort of resting at home.

Before applying sunscreen, we must pay attention to ** care, that is, the water emulsion is used as a primer. In this way, the sunscreen can not only be applied better and better adsorbed by **, but also can play its most role. In this way, we are not afraid of getting a tanner easily when we go out.

It is likely that the sunscreen effect is not particularly good, it is likely that the sunscreen is applied unevenly, and it may be because the ultraviolet radiation is too strong, so this situation occurs. No, the darker it is, the easier it is to tan.

Maybe the sun is really poisonous, and you should go get a parasol when you go out again. Yes, if a person's ** is particularly dark, then the person will be particularly prone to tanning.

Because sunscreen can only play a certain protective effect, it cannot completely block ultraviolet rays. It's not that the darker you are, the easier it is to get a tan.

Sunscreen doesn't mean you won't tan when you use it, and you need to pay attention to the following:

1. Use in advance.

Due to the different active ingredients in sunscreen, some must penetrate into the stratum corneum, and some must form a refractive film, so it must be wiped 20 minutes or 30 minutes before going out in advance to exert its protective effect.

2. Choose appropriately.

It is recommended to choose a sunscreen labeled with both SPF and PA, which means that it can fight against UVB and UVA at the same time. Choose sunscreen according to your skin tone, season, and length of sun exposure, and don't go overboard with SPF, which is not proportional to the effectiveness of sun protection. People who have been indoors for a long time can choose sunscreen products with SPF10 and PA+.

People who are often outdoors, easy to tan, and sensitive to strong light can choose SPF20 or so, PA++; If you work under the scorching sun for a long time or go to the beach, it is best to choose a strong sunscreen product with SPF30 or about 30 and PA+++. Daily use of SPF15-25, PA++ is sufficient.

3. It is very important to wipe enough.

One of the biggest misconceptions people have when using sunscreen is that they don't apply enough sunscreen. The British Association of Physicians recommends at least 30ml of sunscreen for the whole body, including 5ml on each leg, 5ml on the chest and back, 5ml on both arms, and 5ml on the neck and face.

Now that you've decided to take good sun protection, don't let this effect be compromised. The amount of one dollar coin size is more scientifically effective for the whole face.

4. Refill and apply in time.

After applying it for a few hours before going out, the sunscreen effect will gradually weaken due to the dilution of sweat and other reasons, and it will not last all day after applying it once. Therefore, it should be washed off and reapplied in time to determine the continuation of the sun protection effect. Apply every 1-2 hours to ensure sun protection.

In addition to the face, sunscreen can also be applied to other exposed areas such as the neck, arms, etc.

5. Repair Tanhong after the sun.

Sun protection is a systematic effort. After the sun, it is more necessary to calm and hydrate first, followed by whitening and antioxidant.

1) It is because after ultraviolet irradiation, it is dry and the water loss is large, resulting in water shortage, loss of barrier function, and light sensitivity, so it is necessary to calm and hydrate first.

2) Ultraviolet radiation produces a large number of oxygen free radicals, which attack our normal cells and accelerate aging phenomena such as dullness, roughness, and wrinkles, so it is necessary to strengthen the whitening and antioxidant work. Eat more antioxidant foods, such as green foods, blue plums, cantaloupe and various types of melons and fruits.
