Sun umbrellas can still protect against the sun when exposed to water. Can I not apply sunscreen if I don't use a sun umbrella?

Parasols are the most common sun protection products in summer. Many people use parasols when going out. Parasols have a good sun-shading effect. Try not to expose parasols to rain, as the sun protection effect will be affected when they come into contact with water.

It is best to avoid rain and water for sun umbrellas, because frequent exposure to water will affect its UV protection function. The better the sun protection function of the umbrella, the more it should avoid contact with water. If the sun umbrella is wet or dirty, you can use a wet towel to wring out the water droplets and wipe it clean.

In fact, it is still necessary. Holding an umbrella cannot completely block ultraviolet rays. It is better to have a comprehensive protection.

1. Summer parasols can block half of the light but cannot completely protect against the sun. Because visible light and ultraviolet light can reach your skin indirectly through reflections from other places, 20% is reflected by water, and 15-25% is reflected by sand, so you should develop the habit of using sunscreen all year round.

2. In fact, the intensity of ultraviolet rays cannot be underestimated in not only summer, but also spring, autumn and winter, even on cloudy days. Although it is not visible at the moment, melanin slowly accumulates in our body and will affect the skin over time. Be sure to remove makeup every day after applying sunscreen.

3. Parasols have a certain sun protection effect, but some ultraviolet rays will still be reflected onto the skin, so just holding an umbrella cannot guarantee the sun protection effect. You still need to apply sunscreen.

4. If you are outdoors in strong sunlight for a long time, more than half an hour, it is recommended to apply sunscreen even if you use a parasol. If the sunlight is not strong in winter and it does not exceed 1 hour, you can just use a parasol.

It is useful, but you have to buy products that are suitable for you and buy a better sunscreen.

1. Using sunscreen can whiten your skin, but it cannot achieve true whitening. It can only make your skin look whiter after applying it, and the skin's original color will return after removing makeup.

2. Sunscreen refers to cosmetics that contain sunscreen agents that can block or absorb ultraviolet rays to prevent the skin from getting tanned or sunburned. Its main function is to prevent the skin from getting tanned or sunburned, and it does not have a real whitening effect.

3. With the pollution of the environmental air, the hole in the ozone layer is getting bigger and bigger, and ultraviolet rays can irradiate the ground and human skin more accurately, thus endangering human skin health. Therefore, it is still necessary to apply sunscreen every day.

4. Sunscreen is the most classic sun protection product. It contains sunscreen ingredients that can protect the skin from damage by ultraviolet rays and prevent skin tanning and sunburn. Ultraviolet rays are present 365 days a year, so there is no problem in applying sunscreen every day to protect against the sun.

1. There are many places in life that need sun protection, such as working in front of a computer for a long time, which requires certain protective measures for facial skin. The ultraviolet rays in the sun still exist even in mist, cloudy and cloudy weather, so you should always pay attention to sun protection.

2. Develop some good sun protection habits in daily life. For example, regardless of summer, winter, sunny or cloudy, you must apply sunscreen before going out. In the hot summer, avoid going out between 10 am and 3 pm.

3. General sunscreen products are sweat-proof for 30 minutes and waterproof for 80 minutes. If you stay in the sun for a long time, you should apply sunscreen repeatedly, preferably once every hour.

4. Sensitive skin has poor tolerance to some of the functional ingredients added to sunscreen products. Improper use may cause more serious damage to sensitive skin. So if you have sensitive skin, you should pay more attention to the ingredients when choosing sunscreen products.

5. I don't know if you have ever encountered these situations: no matter how crazy you are about sunscreen/whitening essence, your skin is still yellow and black. Have you ever thought that the reason for your dark yellow skin is actually just that you often stay up late and your complexion is not tanned. Choose a sunscreen that suits you, and then apply enough and evenly, about the size of a one-yuan coin, and you can increase the amount appropriately. For sensitive/acne skin, allergic skin, pregnant women, and babies, hard sunscreen (parasols, sun hats, etc.) is the first choice, followed by physical sunscreen, and finally chemical sunscreen. The effect will be seen after applying sunscreen, but if you apply sunscreen about 15-30 minutes in advance, let the sunscreen emulsify into a film (water and other solvents evaporate, prompting the sunscreen particles to be evenly and closely arranged), which will enhance the sunscreen effect. How to judge whether the sunscreen has formed a film: After applying sunscreen, wait for 3-5 minutes, look in the mirror, and the whitening of the skin will be improved and bright. Touch it with your hand, it feels sticky and smooth. It is recommended to use sunscreen after the film is formed, then do isolation, primer, and makeup. According to data, sunscreen can resist 73% of UVA, but suitable hard sunscreen can resist 90% of UVA. Hard sunscreen is relatively simple, such as parasols, sun hats, sunglasses, etc., but the parasols must be large enough, opaque, and have a black coating on the inside to prevent sunburn. Secondly, sun protection should be done all year round on cloudy days and indoors, and sunscreen and hard sunscreen should be used in combination as much as possible. Then apply more whitening skin care products containing vitamin C, arbutin, niacinamide, etc. to inhibit and reduce melanin synthesis. Snowflake skin rejuvenation has an antioxidant effect, reduces melanin synthesis, removes free radicals, whitens and rejuvenates the skin, or whitens and manages skin once a week, snowflake skin rejuvenation management, cherry blossom skin rejuvenation management, antioxidant and anti-aging, prevents tanning and aging, and whitens and rejuvenates the skin.
