In summer sunbreak, keep your eyes clean
Introduction:
The sun is rising, and the most tense protection of the mms in the year has come to an end, with the first priority: strengthening sunscreen. But the sunscreen is going on every year, and you're constantly trying all kinds of new sunscreens. Because after the summer, the skin will still have new spots and stripes, with no dust cover, and the colour will remain dark and yellow, even with red blood and purple silk. By the fall of coolness, to relax, you've accumulated a summer of skin aging, and you've spent a lot of money on beauty salons。
Sunproof what? Ultraviolet。
Why the sun? To prevent the aging of skin caused by sun。
So, summer beauty isn't simple with sunscreen, and only more ways to prevent the aging of light can it be more effective to resist the damage to skin。
What's light age
Skin ageing has both internal and external aspects, and the natural ageing of the skin caused by the decline in gene-controlled cell metabolism, as we call it internal ageing; the ageing of the skin due to external environmental factors, as we call external ageing。
Aging light is the dominant form of ageing outside the skin, and ultraviolet radiation, especially at wavelengths between 320 nm-400 nm, is the main cause of aging skin light。
Aging can occur as early as 30 years of age, and may be the first manifestation of colour anomalies and disorders, such as the beginning of some dotted or irregular brown stains on the face, similar to freckles, which are referred to as sun-light blacks. Some of them have this chromatoma that will be integrated into larger brown spots. There have also been changes in old age and color loss. Since then, the skin has become loose and wrinkled, and some people have seen a small choreography of their faces (face red blood), and others have started to get rough, thick and even orange, so the skin has grown old and lost its beauty。
What are the factors influencing skin light ageing
Activation spectra (with small maps)
The uvcs, uvbs and uvas, among which the uvbs with wavelengths, also known as uvls, are the main causes of early skin decay, while the uva wavelengths are long, causing the most severe damage to skin, reaching the actual skin, destroying the gelatine fibres and elastic fibres, leading to the tanning of the skin, and causing the longest damage to the skin, which is present in sunlight for four quarters of the year, even when it can pass through glass windows and loses the elasticity and tightness of the skin unconsciously. So, in order to keep your skin healthy and young for a long time, we need to use both uvb and uva protections for four seasons。
Physical factors
The different skin shapes of each individual, different skin colours, skin thickness, colour adornment, integrity of the skin angular layer, hydrosis and lipidization, as well as the amount of skin-sorting substances in the skin, may affect the reflection, dispersion, absorption and penetration of the skin to the ultraviolet light, thereby affecting the light aging of the skin. Moreover, if the skin itself causes a skin disease, it increases the body's sensitivity to ultraviolet light and increases the degree of light damage。
Other factors
Farmers, seafarers, geologists and even operators who work in the fields are the people who need to be exposed to the sun for long periods of time, the characteristics of which are most visible. Thus, the skin of light age is called the skin of a sailor or farmer。
The uv content in the sunlight varies significantly from geographic latitude to altitude, and people living in the tropics and subtropical or highlands receive greater uv exposures and are more susceptible to various coloured and ageing features of their skin
In addition, inappropriate exterior photo-sensitive substances such as cosmetics can induce photolytic reactions in the skin。
Added to this is the abuse of human beings by free radicals due to external factors, such as air pollution, dry air, inappropriate lifestyles, such as excessive tobacco and alcohol, late-night overtime, regular oral contraceptives, and inappropriate or excessive sports, especially in the summers, when high temperatures, sun sun, irritating moods generate more free radicals that accelerate the ageing of the human body and skin。
The characteristics of skin light age
Aging light is most visible on the side of the face, neck and upper limbs, and is more pronounced among people of light colour。
Color spots
Cream vein expansion or disappearance
Dark skin
Wrinkles
Orange-like look
How to prevent the aging of light
One escape:
Reduce sunlight and limit the time of ultraviolet exposure, especially by avoiding going out between 10 a. M. And 2 p. M., and avoiding mid-morning of the uv dose。
Or carry sunproof equipment such as shades, suncaps and sunglasses, even on cloudy days。
Search for shelter, but be careful that water, snow, surface, grass, sand can also reflect ultraviolet light. So, don't think sitting under the umbrella of the beach can completely avoid daylight。
Two sunscreens:
Avoidance is, after all, only temporary, and sunscreening enhances sunscreening. However, babies under six months are not suitable for use。
Sunproof items are marked with spf or pa。
The spf (sunprotecingfactor) indicates the coefficient of protection against uvb, and the greater the spf value in a given range, the greater the sunproof effect, the greater the spf value of 30 products, and the rate of disruption of the uvb can reach more than 95%. However, in the purchase and use of sunscreen, the higher the sunscreen factor is considered to be the better, since the higher the coefficient, the more chemicals it contains, the less suitable for everyone, should be determined according to the skin characteristics of the individual, the light conditions and the length of stay outside。
Pa (protection uva) refers to the extent to which the tanning effect on the uva is protected. The defensive effect is three-tier, pa+ is valid, pa++ is fairly effective and pa++ is very effective。
The ideal sunscreen should have the following characteristics: effective absorption of harmful radiation, both against uvb and uva; strong attachment to the angular layer, resistant to water and to sweat; stability in sunlight, air, heat and water; and total non-toxic and harmless。
Trioxidant:
But can the sunscreen of the high spf index and the pa index alone resist the aging of the sun? In fact, whether it be an umbrella, a suncap or sunscreen, it is only possible to isolate ultraviolet light from the outside, not to mention the ageing caused by free radicals, which accumulates daily. Especially in hot summers, high temperatures, sun and moods, air pollution, and stress can create more free radicals and accelerate ageing。
You want the whole summer to be clean? In addition to the outer isolation, you need to wear the inner armor on your skin. - the use of antioxidants is an effective way of preventing skin light aging。
Common antioxidants are vitamin e, vitamin c, beta-carrotin, etc。
Natural vitamin e
Vitamin e has been dubbed the mythical “found of youth”。
As a natural antioxidant of lipid solubility, natural vitamin e protects the cell membrane from oxidation caused by sun, high temperatures, pollution, pressure, removes hate spots and inhibits the production of melanone, gives beautiful internal power to skin, along with your external sunscreen equipment, to resist light aging
Get rid of the free radicals from inside
Free radicals are the product of metabolic processes in humans. But excessive free radicals attack unsaturated fatty acids in the membranes or in the membranes, which oxidize these unsaturated fatty acids, thereby harming cell functions and aging humans. Vitamin e is a lipid soluble natural antioxidant that captures free radicals, protects cellular membranes from free radical oxidation, locks cell internal moisture, removes hate spots, inhibits melanone formation and helps skins to resist light ageing。
(d) the phenol base of vitamin e is free to effectively end the chain reaction of lipid peroxide and eliminate the erosion of the human body by the free base。
Stamps: vitamin e's side chain is directly involved in the oxidation process of the gills, thus inhibiting the activity of the chesamate and reducing the formation of the melanone. Vitamin e also has the effect of spreading end-of-vascular veins, improving micro-cycling, facilitating the transmission of nutrients and the discharge of metabolic waste in the body, thus also contributing to the elimination of “specks”。
Wrinkleproof:
Wrinkles are often generated by loss of fat under the skin, fractures of flexible fibres and degradation of adhesive gelatin tissue. In addition, the degradation of the fat gland can lead to wrinkles. Vitamin e inhibits lipid peroxidation, maintains inter-organizational links and makes skin smooth and flexible。
Water lock:
As vitamin e protects the cellular membrane from free radical oxidation, it helps to repair and consolidate the natural protective barrier of the skin, locks the internal moisture of the skin and provides deep internal and external nutrients。
Vitamin e also promotes the absorption of vitamins c and a and helps cells to better absorb nutrients from external skins and to double beauty effects。

I'll meet you in the sun
And do not think that the sun is sunproof, but remember that sunscreen is enough every two hours, and that every aspect of life should be improved。
Eating: less luminous vegetables such as celery, spices, carrots, etc., during summer festivals make it easier for the skins of love to grow. There should be more of them, such as monkeys, strawberries, tomatoes, oranges, cabbage, etc. In addition, extra tomatoes can protect the sun。
Clothes: wear colored cotton t-shirts. The sunproofness of the clothes depends on the quality and colour of the clothes. The spf value for cotton clothing is approximately 15-40; the spf value for shallow polyester clothing is about 7-10; and the spf value for knitted light clothing is about 4-9。
Diy seconds against the aging light
Wetting at any time: carrying spray-like mineral water with you and adding water to the skin in a timely manner。
Fruit membrane: fresh fruit when natural vitamin e+e+eggs + (learning)
1. Pour out the cucumbers (or lemon, banana, twigs, etc.) and add egg cleans, drop natural vitamin e into adequate feeding halls, mix them up and break them into mud。
2. Be evenly covered in the face and washed with warm water in 15 minutes。
3. This is the most mm-friendly facial film, because natural simplicity not only compensates for water humidity, but also for the effects of whiteness and inflammation。
Tips: why add natural vitamin e? Because natural vitamin e is the pen of the diy face, not only is it white-stained, but it also keeps its skin warm and prevents its thirst due to the length of the mask。
Shape mask:
Appropriate amounts of natural vitamin e oil can be used in combination with haemorrhoids, with light massages and three minutes to wash. The law allows for a smooth, smooth, smooth hair that works at the moment. Long-term use avoids old and yellow hair caused by sun。
How do you fix it
First, the sun is sweating and the salt is thoroughly washed. If it is felt that the face and body have a red fever, it is required to maintain the sedated skin. The cold water or ice towels will be applied to the surface for as long as possible, so that the activated black cells at the bottom of the skin base will be quieted down and the continuous secretion of the black is controlled. You can also use iced make-up tampons (normally frozen in refrigerators) to lighten the red and hot parts of your face, which can inhibit inflammation。
Vitamin e oil was then applied to the fever, or the face of natural vitamin e was applied, with restoration and dilution. It is important to note, however, that the sun should not be sunbathed immediately, otherwise the skin would be prone to brown spots。
You can try the diy after the sun
First, glucose and glycerine are boiled at 3:l ratio and cooled for use
This was followed by a spoonful of natural vitamin e and a few drops of mint oil, which were evenly mixed and placed in the freezer。
It's cold and clear when you don't take your face out in due course. It has a good calming effect on the skin of the sun。

The summer sun-proof guide
Why the sun
Appropriate sunlight is beneficial to the human body, but excessive or prolonged exposure to the sun accelerates skin ageing, induces skin disease when it is severe, even worse, or causes skin cancer。
Who's the sunproof guy
The sunlight mainly includes ultraviolet, visible light and infrared. And the sun is red and tan, and the main cause of skin damage is ultraviolet light。
How does ultraviolet light damage the skin
The uvb has a strong capacity for direct skin injury, which can lead to sunburning of the skin, causing heat, skin removal, red spots, etc。
Uva has a strong permeability and 80% of uva can penetrate the top of the skin, causing damage to lipids and glue proteins, causing skin ageing and even cancer。
So..
The sun's not about visible light
It's uvb and uva in ultraviolet
When will ultraviolet light be the strongest
In a year, late spring and summer were the strongest uvs。
One day, at noon, the uv's strongest。
Three key words for sunproofing
10 - 14:00
Avoiding prolonged outdoor activity
Select the sunproof shield
Use sunscreen properly
Spf refers to sunproof coefficients and the number of times the skin resists ultraviolet light. The larger the value behind the spf, the stronger it is against the uvb, the stronger it is against sun。
Assuming that a person is not sunproof, the skin is red for 20 minutes in the sun. Using sunscreens with a spf value of 30, it would theoretically take 20,30 minutes (i. E., 10 hours) for the skin to be red。
But the spf isn't as high as possible
The higher the value, the more other additions
The greater the skin burden
Pa means the effective time of protection against uva. The more the pa+, the stronger the uva, the stronger the sun。
Some countries have sunproof products without pa markings
Replace by the following:
Broad spectrum (spectrum sunproof)
Extra uva protection
What about sunscreen

What about sunburn
After the tan, the skin is red, it has a patch of red stains, it is accompanied by burns of pain and severe skin death, which is actually a skin disease called solar skin。
It's common in the sun
Do you need sunscreen
[necessary]
The sun is dry, the weather is dry. Uva in uv is as strong as in the dark sky, and can reach about 70% of uv strength in the sky without sunlight。
Does sunscreen work immediately
[wrong]
The sunproof products include both physical reflection and chemical absorption, which are required until they are absorbed into the skin to act as sunproof. It is generally recommended that sunscreen be applied 30 minutes before leaving。
Do sunscreens need makeup
[necessary]
If a low multiple is used to protect the sun, normal cleaning is sufficient. If high-multiplier waterproof sunscreen is used, it is recommended to use off-coup products。
It won't work if it's tanned
[wrong]
Sunproofing is not tan-proof, but tan-proofing. The sun has been tanned, as well as the prevention of further light ageing. When the skin is tanned, self-protection mode (forming melanol, etc.) is automatically activated, but uv rays continue to be absorbed, tans are tanned for long periods, melin is formed, and skin diseases are induced in serious cases。
In summer
Remember to keep the sun warm
