Having white and tender skin is the dream of most mm. It is a pity that the mm of natural beauty is few and few. This summer, let's take a look at the magic whitening formula of summer, so that you have different skin.
Don't pay attention to the concept of sunscreen at night
More and more women pay attention to the sun protection during the day, but the sun protection and whitening at night are often ignored by people, especially when going to the pub or watching movies, because halogen lamps and fluorescent lamps contain strong ultraviolet rays, which are easy to tan. It's too late to regret until you get sunburnt and get old!
Concept 2 you don't need sun protection indoors or in a car
What is' ultraviolet '? In fact, the' ultraviolet 'in people's mouth can be subdivided into long wavelength UVA, medium wavelength UVB and short wavelength UVC. UVA will refract into the room, also known as' indoor ultraviolet'. It can go deep into the dermis and destroy collagen, elastic fibers and even fibroblasts. Therefore, UVA can not only stimulate pigment synthesis and make skin 'Black', but also cause skin damage Aging and fine lines are the main culprit. Therefore, for the sake of skin health, drivers should not only pay attention to sunscreen, but also install a protective film containing ultraviolet rays on the windows.
Idea 3 no sunscreen for umbrella
Every summer, you will see that the beautiful eyebrow of the street is supporting a handful of umbrellas. But what if they ask for their sunscreen lotion? Most people will ask you in reverse: 'I have already had an umbrella, why do I need to apply sunscreen lotion?'
In fact, there are more crises hidden in the umbrella! High quality umbrella can effectively block ultraviolet rays, but no matter how effective it is, it can only block direct ultraviolet rays at best. But it's useless for ultraviolet rays such as reflection from the ground and refraction from glass windows. Only by directly applying sunscreen lotion on the skin surface can we completely isolate all pervasive ultraviolet rays.
Concept 4 no sun protection on rainy days
It's only when people think about the sun that they'll see the sun. But in rainy days, because there is no sense of warmth and heat in the sun, I intuitively think there is no need for sun protection.
In fact, although clouds can block infrared rays, they can't block ultraviolet rays, especially long wavelength UVA! Although infrared rays are blocked by clouds, they won't feel scorching by the sun, but ultraviolet rays still hurt skin unconsciously!
Idea 5 only once a day is enough
Many people think that it is enough to apply sunscreen every day before going out. Besides, they don't have time to make up during work or travel. In fact, this should be dealt with in a specific way. If the weather is sultry and prone to sweating, sweat will take away the sunscreen on the skin surface, so wearing sunscreen is definitely not once and for all. Instead, reapply sunscreen every two or three hours by applying 5 teaspoons of the equivalent of 100 grams of sunscreen evenly to the body and face, but it should be noted that the same amount should be used in the shade and in the sun.
Concept 6 don't use sunscreen if you don't get sunburn easily
'I can't get dark in the sun! So I don't need sunscreen at all.'.
The above words can often be heard from the conversation of the neighbors while taking the bus. In fact, the skin is not easy to Tan 'white beauty' should do a good job in sun protection! Because 'white beauty' is born with white skin, the amount of melanin in the skin is naturally less, that is to say, the protective cover used to resist 'evil' ultraviolet rays is relatively less. Although the sun is not dark for a while, the accumulated UV damage in the long run is no less than that of 'black beauty'. In this way, the chance of black spots, wrinkles and skin cancer in the future is many times greater than that of "black beauty"!
Concept 7 sunscreen that didn't run out last year will be used again this year
If you continue to use sunscreen that you didn't use last summer, you don't have sunscreen. Remember, sunscreen must use this year's new products! Why? Because sunscreen contains sunscreen ingredients that will deteriorate and lose their sunscreen effect after a year. Just as many skin care products are marked with a warning that they will be used up 12 or 6 months after opening, the sunscreen after being turned on should be discarded after a year of shelving. Even if there is no sunscreen turned on, after a year, the effect is not as good as before, so give up.
Idea 8 sunburn doesn't need sun protection
Some people think that if you work in the sun every day and your skin is tanned, you don't need sun protection. In fact, suntanned skin is more need sun protection, because suntanned skin will also be damaged by UVA. Skin thickening and melanin production are the performance of skin self-protection, but melanin can only partially absorb UVB, and has no function of preventing UVA absorption. Therefore, it is essential to create a barrier between the sun and the skin.
Idea 9 repair in autumn after sunburn
The strong sunshine in summer is available every day, so it's useless to treat sunburn; when the sun weakens after autumn, it won't recur. You can't have this idea.
In fact, sunburn treatment should be carried out on the same day or even at that time! The earlier the treatment time is, the smaller the degree of skin damage. This can not only quickly reduce the reaction of skin redness, swelling and burning, but also help to slow down the damage of ultraviolet rays.
Concept 10 eyes and lips do not need sun protection
In fact, eye and lip skin is a very delicate part of the human body, ultraviolet merciless invasion will greatly damage them. Therefore, it is very necessary to apply sunscreen products on your lips in midsummer and choose high-quality anti ultraviolet sunglasses.
Concept 11 old people don't need sunscreen
Many old people only use ordinary skin care products when they go out, never use sunscreen. They think sunscreen is for young people. In fact, there is less water in the body of the elderly, and the skin is dry due to water loss and less secretion of skin glands. The skin is thinner, the epidermis is is atrophic and the protection ability is poor. Therefore, under the ultraviolet radiation, it is more likely to cause the increase of senile plaque and even cause skin problems. Therefore, the elderly should also attach great importance to sunscreen.
