The importance of sun protection: Sun protection is also needed in spring

The sooner you start applying sun protection, the better your skin will be. Experiments have shown that people who have always done a good job of sun protection will look more than 10 years younger than those who do not when they reach the age of 50, proving that ultraviolet rays can cause great damage to the skin. Sharp contrast

Sun protection refers to taking some methods to block or absorb ultraviolet rays in order to prevent the skin from getting tanned or sunburned.

1. Prevent sunburn. Sunburn is medically known as solar dermatitis. Prolonged exposure to the sun can cause acute redness and swelling of the skin, and in severe cases, lead to the formation of blisters. Sunburn often causes more serious skin problems, such as itching and peeling, and these symptoms cannot be solved by skin care products. So to prevent sunburn, you must remember to apply sunscreen.

2. Prevent photoaging. Sunlight is the most direct external factor that causes skin aging. Unprotected skin will prematurely develop wrinkles, spots, rough skin and other phenomena due to the sun. Sun protection can slow down this aging caused by external factors.

3. Prevent suntan. UVA in sunlight is the cause of skin darkening. Once the skin is tanned, whitening it becomes more difficult. In other words, if you pursue the state of "whiteness covers a hundred uglinesses", the most effective way is to prevent them before they happen. Therefore, choosing a sunscreen with the PA logo is the best choice.

UV stands for ultraviolet rays

UVA: It exists all year round, whether it is day or night, rainy or cloudy. It can cause the main cause of aging and is easily ignored by women. In this case, day cream and foundation with sun protection factor are generally used.

UVB: Noon, April to November in the south, generally late May to September in the north, noon. Being exposed to the sun can cause burns on the skin, redness, tanning, and spots. In this case, you need to use sunscreen.

UVC: Dust in the air, car exhaust and polluted environments, etc. (light in the air can easily cause skin diseases such as skin cancer, psoriasis, etc.). To deal with this situation, clean it every day.

2. Computer radiation can penetrate a person's body.

Due to the above points, you cannot choose sunscreen casually. The wrong choice will cause many skin diseases, such as skin cancer, psoriasis, etc. Ultraviolet rays can penetrate everywhere, which also proves that women need to protect themselves from the sun at all times.

3. Beauties who like swimming should pay attention! Ultraviolet rays stay longest in water. This is why the water in outdoor swimming pools is warm or hot in the evening. After swimming, I felt my skin became darker.

Myth 1 : Ultraviolet rays are only very strong in very hot conditions.

Reality : UV rays do not generate heat. For example, when people climb a mountain, the higher they go, the cooler the mountain breeze becomes, and the stronger the ultraviolet rays become. For every 1,000 meters you go, the UV rays increase by 10%. The same is true at sea: the sea breeze makes you feel cool, but the ultraviolet rays at this time are already extremely strong.

Myth 2 : When the clouds are thick on cloudy days, ultraviolet rays will not harm the skin.

The truth : Clouds have almost no shielding effect on ultraviolet rays. 90% of ultraviolet rays can penetrate clouds. Only dark and thick rain clouds can block some ultraviolet rays.

Myth 3 : Sunscreen will provide sun protection immediately after application.

The truth : Since the active ingredients in sunscreen must penetrate into the surface of the stratum corneum to exert a long-term protective effect, it is necessary to wipe it off 30 minutes before going out, and replenish it again before going out. The dosage used must be at least 1 to 2 ml each time to achieve the best sun protection effect.

Myth 4 : Forgetting to apply sunscreen a few times occasionally will not have much impact on your skin.

The truth : Sun exposure is cumulative, so even if you are only exposed to the sun indirectly, the damage to your skin will accumulate over a long period of time. You may not see the consequences immediately, but over time it will cause tanning, spots on your face, loss of skin elasticity, wrinkles, and aging.

Myth 5 : As long as you apply sunscreen before going out, your skin will be safe all day long

The truth : After applying sunscreen products to exposed areas for several hours, their sunscreen effect will gradually weaken due to dilution by sweat and other reasons, so they should be washed off and reapplied in time to ensure the continuation of the sunscreen effect.

Myth 6 : My skin is already tanned, so applying sunscreen won’t help.

The truth : The skin turns brown after sun exposure, indicating that the skin enters a self-protection state. Thickening of the skin and the production of melanin are manifestations of the skin's self-protection. However, melanin can only partially absorb UVB, thus protecting the skin from damage, but it has no function of absorbing UVA. Therefore, when going outdoors, a barrier between the sun and your skin is essential.

Myth 7 : I am already using lotion and foundation that both have sun protection values, so the sun protection effect should be the sum of the two.

Reality Check : The only real sun protection you get is from the product with the higher SPF value, so there is no need to use two sunscreen products at the same time.

Myth 8 : Using a parasol can provide shade

In fact, 50% of ultraviolet rays can pass through the isolation of parasols and harm the human body; the same is true for glass, which can only isolate medium-wave ultraviolet rays (UVB), while long-wave ultraviolet rays (UVA) can penetrate the glass unimpeded, so sun protection is also needed when sitting indoors.
