When summer comes, I often receive messages from people on WeChat and backstage:
A: "I am mixed with oil, just like you. What do you use for sun protection?"
B: "Yinyin, with neutral skin, is easily sensitive. Do you have any sunscreen recommendations? Not too expensive. "
C: "Go to the seaside to play. What sunscreen for adults is waterproof and easy to use?"
I believe everyone knows how important sun protection is. In the British BBC, a documentary "The Truth of Beauty" revealed that the biggest culprit of long wrinkles aging and blackening turned out to be: sunbathing.
ultraviolet rays in solar rays are divided into short-wave ultraviolet rays (UVB) and long-wave ultraviolet rays (UVA). UVB is responsible for "sunburning" you, causing skin redness, blisters, peeling and aging. However, the penetration is weak and can be blocked by clothes, hats, umbrellas and sunscreen.
UVA is responsible for "tanning" you, entering the dermis, forming spots, wrinkles and so on. Penetration is very strong, even if it rains, it can go through the clouds to the ground, and even penetrate the glass, and those lady-class skin care products can't easily reach the dermis for repair.
"Raising children does not prevent old age, but sun protection prevents old age." Words are not rough, the key to anti-aging is to do a good job of sun protection first! Sun protection is not only to prevent sunburn and sunburn, but also to prevent photoaging!
Every summer, major brands go all out to make sunscreen to seize the market. One brand has introduced several sunscreens, which have different SPF, waterproof isolation and touch-up functions.
I also found many new brands that I haven't seen before this year. Before recommending sunscreen to you, I made a sunscreen evaluation for your reference by comparing several new sunscreens with those for my own use, plus the sunscreens of my company's sisters.
Everyone will feel different when using sunscreen. This evaluation will be compared from the dimensions of sunscreen composition, sunscreen effect, waterproof ability, use experience and price, hoping to help those who are struggling.
most sunscreens on the market can be divided into physical sunscreen, chemical sunscreen and materialized sunscreen according to sunscreen components.
Physical sun protection
Using reflective particles, zinc oxide and titanium dioxide are common. Protect the skin by blocking, reflecting or dispersing ultraviolet rays. Usually only stays on the skin surface, will not be absorbed by the skin, is mild, and is the first choice for children, pregnant women and sensitive muscles.
There are relatively few pure physical sunscreens in the market. We chose two physical sunscreens that are more common in the market for this evaluation.
chemical sun protection
a film is formed on the skin surface, and the purpose of sun protection is achieved by absorbing ultraviolet rays. Common chemical sun protection components include benzophenone, ethyl hexyl salicylate and so on. Moreover, chemical sunscreen molecules will be absorbed by the skin and eliminated by human metabolism.
This time, we chose six chemical sunscreens, except Rock Zoo and LaPulovce, the other four are well-known brands.
combination of physical and chemical sunscreen
sunscreen cream containing both physical sunscreen ingredients and chemical sunscreen ingredients. Not only can it cover a more comprehensive ultraviolet protection band, but it can also make the sunscreen feel better and more stable, and it is suitable for more scenes and people, so most of the sunscreen on the market is materialized.
Therefore, the combination of physical and chemical sunscreen in this evaluation also accounts for half, and there are 7 models in one * * *.
No matter what kind of sun protection, its function is to help us resist the damage of ultraviolet rays and reduce the problems of skin oxidation and aging. Next, look at other ingredients, mainly sensitive muscles that need special attention.
alcohol
It can be seen that alcohol is added to half of the sunscreen, because alcohol is a good organic solvent, and on the other hand, it can make the sunscreen feel better, making it feel icy and cool. However, pregnant women, sensitive muscles and people who are allergic to alcohol should pay attention to
preservatives
Although these contain preservatives, they do not contain controversial preservatives, but sensitive muscles need to pay more attention.
essence
essence is not a poison, as long as it is not allergic, there will be basically no problem in using it, and if the smell of sunscreen is good, it is also a plus item.
Talcum powder
Talcum powder is mainly used in sunscreen cream to add a smooth touch to the texture. Japanese sunscreen prefers this ingredient. It can be seen that the five items containing Talcum powder in our sample are all Japanese sunscreen.
the sun protection value of sunscreen is a very important reference standard, which is related to whether it has the effect of sun protection and sun protection.
first of all, we should know that UVA and UVB in ultraviolet rays are really harmful to human body, and we also wear sunscreen to resist the harm of UVA and UVB in ultraviolet rays to our skin.
UVA
UVA is a long wave, which can reach the deep layer of the skin directly, causing the skin to turn black. PA value reflects the ability to protect against UVA. The more "+"behind PA, the stronger the protection against UVA. Usually, one more+sign can delay the tanning time by 2-4 times.
UVB
belongs to medium wave, which acts on the surface layer of skin, taking effect quickly and causing skin to turn red. The SPF value reflects the ability to protect against UVB, and the coefficient behind SPF refers to a time range to protect the skin from ultraviolet rays. The higher the SPF value, the longer the sunscreen time.
Take chestnuts as an example. If a person's skin turns red after 1 minutes in the sun without sun protection measures, then:
But the higher the value, the better, because the higher the value means that the more chemical components are added, the worse the air permeability is, and it is easy to cause pore blockage. In fact, you should choose different sunscreen according to your own needs.
to sum up, SPF3 and PA+++ sunscreen are enough for daily commuting; If you go out for shopping, outdoor sports and outdoor play, choose SPF5 and PA++++ sunscreen; It is best to choose SPF 5, PA+++++sunscreen products with strong waterproof function for swimming.
except for the low SPF of Kerun, the SPF of 934 is relatively low, and the other SPF values are SPF5 and PA++++, and the overall difference is not very big.
It's so hot in summer that you start to sweat soon after going out. If the waterproof ability of sunscreen is too poor, as long as you sweat, the sunscreen you put on before going out is basically white. Therefore, even if you are not going to the seaside, if you are a reader in love sweating, it is recommended to choose a sunscreen with certain waterproof ability.
We did the test of directly dropping sunscreen into water. After stirring, we can also see how waterproof the water is by the clarity of the water in the cup.
Also apply it to your hands and wait for the sunscreen to form a film, then spray water to test the water resistance. This waterproof ability test is very intuitive. After the film is formed, it is sprayed with water, which shows that it is waterproof. If the water drops are white, they are slightly soluble in water; If the water drops are clear, they are insoluble in water.
according to two tests, I divided the waterproof ability of these 15 models into three grades: strong, medium and weak.
strong
Kerun, Xinbi, la roche-posay, SOFINA, LaPulovce, Runbaiyan, Annai Sun, Shiseido, Aubrey
medium
Mistine, L 'Oreal, Esteban
weak
Rock Zoo, 934, Neutrogena
. Daily commuting with moderate waterproof ability is very suitable. If you sweat for a long time, you need to apply it again.
according to the fluidity, it can be divided into texture of correction fluid, texture of emulsion and texture of cream, and the texture of correction fluid and emulsion will be more moist and easy to push away.
1. Kerun
The texture of the correction fluid is very fluid, and the skin feels ordinary but not oily. At first, it is a little white, and it will become more natural after a while. It is suitable for pregnant women and sensitive muscles, and is suitable for neutral skin and oily skin.
The texture of the cream is not very easy to push, and it is a little white, but it forms a film quickly and is not greasy. It is also suitable for pregnant women and sensitive muscles, and can be used for normal skin and oily skin.
the texture of the emulsion is very refreshing, and it is a little oily at first, but it has improved a lot after the film is formed, and the oil skin will feel a little oily.
the texture of emulsion is not very easy to push, and the skin feels greasy, which will be obviously shiny, not suitable for oily skin, and dry skin will be better to use.
The creamy texture with no fluidity has obvious heavy feeling after being pushed away, and it is not refreshing and greasy. It needs to be coated with loose powder to neutralize some greasy feeling, which is not suitable for oily skin, and neutral skin will be more suitable.
The emulsion texture with light water feeling is very moist and easy to push away, and it forms a film quickly, with good skin feeling, not heavy and greasy, which is more suitable for mixing muscle and oil skin.
The emulsion has good texture, good fluidity and easy pushing, but the film formation is slow, and the back is still oily, which is suitable for dry skin.
The texture of the correction fluid is very malleable, with a little whitening effect. It is moist and suitable for oily skin and mixed muscles.
The texture of the cream needs to be circled for many times before it can be completely spread evenly. The film formation is slow, and then it turns white seriously. Moreover, the skin feels particularly greasy and prone to acne. It is not recommended to use neutral skin and oily skin. I'm a greasy skin prone to acne. I used this 934 for three days, and my makeup was removed every time. However, I still grew several closed mouths and then broke out. It is not very recommended for friends who are prone to acne.
The texture of the cream is weak in fluidity but easy to push, and it will burst into water drops when it is spread. The texture is very refreshing and moist, with a slight moisturizing effect, and both oil skins and mixed oil skins will like it.
The texture of the emulsion is not strong in fluidity, but it is easy to push away. After the film is formed, it is dry and not oily, but it is slightly white, and the oil skin will feel a little oily.
The texture of the correction fluid is moist, malleable and easy to push away. It is slightly oily. After film formation, it is not oily and slightly shiny. Dry and neutral skin will like it, and oily skin can also be used.
The texture of the correction fluid is very fluid, refreshing and non-greasy. After film formation, it has a foggy skin feeling, which is suitable for oily skin or mixed oil skin.
The texture of the correction fluid is good, the film is formed quickly, it is refreshing and will not stick, and it is more suitable for mixing muscle and oil skin.
The texture of the correction fluid is moist and malleable, but the film formation is slow, and there will be greasy feeling in the back, which is more suitable for dry skin and normal skin.
In addition to texture, the skin feeling of the upper face is also very important. After all, no one wants to take a long time to finish painting. They don't like the feeling of greasy or muddy painting on their faces, and they will lose points if they feel dry.
Because everyone has different skin types and different requirements for skin feeling, the skin feeling of each sunscreen will be different. This part of the evaluation has a strong subjective feeling, which is for your reference only, and it should be based on your own feelings.
L 'Oré al, la roche-posay, Rock Zoo, 934 and Oprah are oily, which are obviously oily when applied to hands, and some of them will have an oil film when dropped in water. Several models of the texture of the correction fluid all form films quickly, and Lapris will burst into water droplets when rubbed, which makes the skin feel good ~
Several models of sunscreen that participated in the evaluation this time have different specifications, and more specifications will be more cost-effective than less ones. We only calculate the price of each 1ml sunscreen according to the actual evaluation specifications and the daily price of a treasure flagship store, for your reference and comparison.
From the price per ml, it is mainly concentrated at 1.76~3.97 yuan. Big brands like L 'Oreal and la roche-posay are not only used in general, but also relatively expensive. Shiseido is the most expensive one this time. Mistine in Thailand is easy to use and cheap, so it is no wonder that it has been on fire for so many years.
finally, let's make a summary. You can refer to the contents of the following table and choose according to your actual situation and needs.
It is recommended to remove makeup by combining physical sunscreen with materialized sunscreen, because it contains zinc oxide and titanium dioxide, which are macromolecular substances, and it is easy to block pores if they are not removed. Pure chemical sunscreen does not need to remove makeup, because it will be absorbed by the human body, just wash it off with facial cleanser.
There are many kinds of sunscreen, and many ingredients are matched with each other to achieve better sunscreen effect and better skin feeling experience. Everyone will use the same model differently, only they can use it well.
