How is the skin darker in autumn than in summer?

The skin is darker in autumn than in summer. Autumn is coming, and it is also a very dry season, so our skin is very prone to some problems. At this time, it is necessary to deal with the problem in time. Let's share the reasons why the skin is darker in autumn than in summer.

What should autumn skin do if it is darker than summer? 1 skin darkening in autumn may usually be caused by ultraviolet radiation or slow cell metabolism. At the same time, it does not rule out the reasons such as lack of water on the skin, and it needs to be conditioned according to the reasons.

1, ultraviolet radiation: skin darkening in autumn may usually be due to lack of sun protection in summer, which will gradually darken the skin. If you want to make your skin whiten quickly, you can improve it by injecting whitening needles under the guidance of a doctor.

2. Slow cell metabolism: Generally, due to the gradual cooling of the temperature in autumn, the garbage on the skin may not be completely discharged, resulting in blackening of the skin. Generally, vitamin E cream and vitamin B2 ointment can be used under the guidance of a doctor to improve it.

3, skin water shortage: generally dry in autumn, it will lead to skin water shortage. If you don't replenish water in time, it may lead to dry and dull skin. Under normal circumstances, you can use some moisturizing products that suit you and drink plenty of water to replenish water.

Why does the skin turn black in autumn?

Just after the hot summer, the dry climate in autumn will reduce the ambient temperature and humidity, and the skin is not easy to retain moisture. Normal stratum corneum usually maintains 15~20% water content, but with the decrease of temperature, skin blood vessels will contract.

When the secretion of sweat glands and sebaceous glands decreases, the water content of stratum corneum may be lower than 10%! So the skin will become rough and black. The phenomenon of desquamation began to increase wrinkles and even cause dermatitis and eczema.

After autumn, vegetation will wither and wither, which is easy to hurt people. Experts also said that the climate with large temperature difference can easily make people feel irritable and dry. Common symptoms are depression and irritability, which can lead to unwillingness to work, insomnia and headache. In this case, the skin is also easy to feel pressure and lifeless, unlike the rosy, smooth, soft and tight state before.

How is the skin darker in autumn than in summer? Although the sunshine and ultraviolet rays in autumn are not as strong as those in summer, there are many other factors that may really make the skin darker than in summer!

The temperature drops and the air is dry.

The temperature drops sharply in autumn and winter. The more cold air, the less water vapor and the drier the air. Especially in the north, dry skin in autumn and winter is the same problem for most people.

At the same time of these changes, the oil secreted by the skin itself has also decreased, and our skin needs to keep the moisture in the stratum corneum at around 20%. The decrease of temperature and humidity increases the challenge to the daily work of skin.

The air quality is worrying

Automobile exhaust, coal burning for heating, air drying and fine dust increase. These air pollution not only affects the lungs, but also does great harm to the skin.

After the particles in the air are attached with harmful substances, they will fall on the skin surface, causing harm to the skin and inflammation.

Pay attention to protection

So the skin problems in autumn are basically: lack of water and dryness, and skin inflammation.

If you don't change your skin care strategy quickly, avoid harmful operations and add extra protection, you may have skin sensitivity or even dermatitis, and your skin will be dull and look darker than in summer.

So how should we protect it?

1, sun protection.

Use sunscreen+hard sunscreen as long as you like. But be careful to avoid particularly dry sunscreen.

2, cleansing.

Do not frequently use soap base and scrub particles for cleansing. These are the cuticles of the skin. Continuous high-intensity use will reduce the protective function of skin barrier and cause the aforementioned skin problems.

3. Essence.

Like cleansing, you can reduce the use of high-concentration salicylic acid and vitamin A alcohol products.

You can choose the ampoule essence combined with compound fruit acid and hyaluronic acid, which can remove old and waste keratin and moisturize and replenish water for the skin.

4. Water temperature.

The water temperature of washing and bathing should not be too high or too cold, and the cleaning time should be appropriate.

It is recommended to wash your face with warm water at 25-30℃ to avoid alternating hot and cold water. The temperature difference is too large, which will irritate the skin!

The skin in autumn is darker than that in summer. 3. The skin is dark, but it has little to do with the season. But why does autumn feel darker?

One is in summer, when the ultraviolet rays are strong, you may not do enough sunscreen or the sunscreen effect is not good, and then your skin color will gradually turn black. In autumn, you may find it more obvious.

The other is that dark skin color is also related to sleep. If people don't sleep well or sleep late at night, their skin color will be very dark or dull.

These all need to be adjusted from the lifestyle. One is to pay attention to sun protection. Not only can you wear sunscreen. Sometimes you can cover it with an umbrella, scarf or mask, which can achieve the ideal sun protection effect. Also, be sure to take a rest. Be sure to work and rest on time at night and go to bed early. Drink more warm water, eat more fruits and vegetables, and do more exercise. This will gradually improve the skin color.

Reasons for sun protection in autumn

The amount and intensity of ultraviolet rays reaching the ground are mainly determined by the solar altitude angle and the degree of attenuation of sunlight in the process of passing through the atmosphere.

The height angle of the sun is the largest in summer, but there is much rain and thick clouds in summer. In the process of sunlight passing through clouds, ultraviolet rays decrease.

Although the solar altitude angle decreases in autumn, the clouds are thinner, the weather is dry and the rainfall is less, and the influence of clouds and moisture in the atmosphere on the reduction of ultraviolet rays is reduced. Finally, there may be more ultraviolet rays reaching the ground than in summer!

UVA you ignored

Ultraviolet rays in the sun include UVB and UVA. In summer, the sun is fierce and contains a lot of UVB, which is easy to cause sunburn and tanning! In autumn, when the sun shines obliquely, the UVB content in the sun drops obviously. But UVA doesn't have a big gap because of the season. The warm sunshine in autumn will make people forget that it is also lethal!

Autumn ultraviolet killer UVA

Features: Strong penetrating power, can penetrate clouds and glass directly to the dermal layer of skin.

Harm to skin: stimulate melanin production, destroy collagen and elastic fibers, and skin will appear dark spots and aging unconsciously.

Sunscreen in autumn is essential.

The weather in autumn is dry, the metabolism of human skin is slower than that in summer, and it is also exposed to the sun. The process of whitening recovery is longer than that in summer, and the sun protection work cannot be slack! Similarly, we should also do a good job in sun protection in autumn, try to avoid going out around noon and avoiding sun exposure. When going out, you should take protective measures, such as applying sunscreen, playing parasols and wearing long-sleeved trousers.
