What should you do if you get sunburned while traveling? Can you whiten your skin by hiding at home after tanning?

I went traveling with my friends. Although I heard that the destination was a plateau, I thought it would be no problem since it was only over 4,000 meters above sea level. However, after we went there, not to mention the altitude sickness, My face is completely tanned. Sometimes the sun is shining brightly and I am dripping with heat and sweat, and sometimes the cold wind is freezing. It is really unbearable. Although there is no scenery, my face is peeling from the sun. What should I do?

1. What should you do if you get sunburned while traveling

Going to a plateau without applying sunscreen? Skin ages prematurely!

When traveling to the Qinghai-Tibet Plateau, many "travelers" will proudly post before-and-after photos online: before entering Tibet, their skin was fair and rosy, and when they returned from Tibet, they were "caressed" by the strong ultraviolet rays on the plateau. Underneath, the skin is dark and shiny. In order to show that they are not "feminine", some male "alert friends" will also specially mark under the comparison photos: no sunscreen.

Wang Xiaoguang pointed out that people with dark skin will look older than their lighter-skinned peers. In fact, more than 90% of premature skin aging can be attributed to excessive sun exposure. If you don’t wear sunscreen when traveling to plateaus, beaches, or deserts where the sun is strong, it is tantamount to deliberately aging your skin prematurely.

How to tell if your skin has been sunburned? Wang Xiaoguang pointed out that sunburned areas may feel burning, itching or stinging. In mild cases, the rash may gradually subside within 1 to 2 days, with scaling or pigmentation.

Some time ago, a picture of an African player being sunburned in China went viral on the Internet. On the dark upper arm of this African brother, there is a patch of skin that is obviously darker. "Compared with white and yellow people, black people have a relatively lower chance of getting sunburned." Wang Xiaoguang pointed out that people with light skin are more likely to get sunburned because there is less melanin in the skin, and melanin can absorb ultraviolet rays and protect against ultraviolet rays. Penetrates into the dermis.

Skin receiving "sunlight exercise" can help reduce sunburn

Preventing sunburn on the skin is not just about applying sunscreen, wearing long-sleeved clothes, holding an umbrella and wearing a hat. There is a way to go. Wang Xiaoguang suggested that you might as well let your skin gradually undergo "sunlight exercise" to moderately increase the melanin in your skin. Simply put, you can make yourself slightly darker.

For those who rarely come into contact with sunlight, the exposure time can only last for a few minutes at the beginning, and then gradually increase. This can increase the melanin in the skin, thus strengthening the resistance to ultraviolet rays. Defense ability plays a protective role.

The most important thing to do after sunburn is "cold and wet compress"

What to do after sunburn? Wang Xiaoguang recommends cold and wet compresses first. Dip a cotton pad into ice water and apply it on your face for about 15 minutes until the skin returns to its original color and temperature. Then, cleanse your face with a mild cleanser and apply some moisturizing gel.

After doing a certain amount of sunbathing, vitamin C supplementation is very important. Vitamin C can inhibit the growth of melanin. In addition to oral vitamin C tablets, you should also take more in your diet. There are many fruits and vegetables containing vitamin C, such as tomatoes, lemons, cucumbers, carrots, kiwis, apples, citrus, etc. Eat more of these fruits and vegetables It can maintain the healthy and whitening condition of the skin.

If you have severe sunburn, especially if you have blisters on your skin, the most important thing is not to apply any products and avoid rubbing the skin to avoid rupturing the blisters. You can try using a makeup remover dipped in ice water. Pat your face gently to cool down your skin, and see a dermatologist as soon as possible.

Routine treatment: Apply wet compresses after sunburned blisters

1. For those with erythema, no blisters and pain, you can use 2.5% indomethacin solution (pure vinyl alcohol, propylene glycol, Dimethylacetamide, the ratio is 19:19:12) for external application.

2. When bullae and exudate are long, you can use 2% to 4% boric acid solution; milk solution (50:5 milk and water) or physiological saline (one teaspoon of salt dissolved in 500 to 600 ml of water) ) and wait for the solution to be applied wetly, no more than 20 minutes each time, no more than 3 times a day, until the blisters dry up. Most blisters do not require treatment.

3. For itchy sunburn, antihistamines or analgesics can be taken orally: cyproheptadine 2 mg 3 times a day; chlorpheniramine 4-8 mg orally 3 times a day; astamine 10 mg orally once daily. Painkillers include aspirin 1 g orally three times a day; paracetamol 0.25 to 0.5 g orally four times a day. For severe sunburn, 10 mg of prednisone can be taken orally 3 times a day for 2 to 3 days, but it should be applied 36 hours or less after the sunburn. It can reduce redness, swelling, heat and pain.

Traditional Chinese medicine theory: Sunburn is caused by "Yang poison invaded from the outside and heat-heat poison invaded from the inside"

Wang Xiaoguang said that Chinese medicine believes that sunburn is "Yang poison invaded from the outside and summer-heat evil poison invades internally". Internal invasion, poor drainage, burning of the skin, and stagnation in the skin.” The treatment method is to clear away heat and detoxify, and should be combined with external treatment.

If the skin color is red and there are erythema, it is necessary to clear away heat and relieve itching. You can use Sophora flavescens, Aspergillus alba, and Baijili for external washing. For those with only erythema but no blisters, or those with small blisters that have not burst, you can use 30 grams of Sophora flavescens, 30 grams of dandelion, 20 grams of wild chrysanthemum, or 30 grams each of Sanguisorba and Purslane in decoction. After cooling, apply wet compresses every time. 30 minutes, 3 to 4 times a day, 1 dose a day. Or apply it externally with Sanhuang lotion, 1 to 2 times a day.

If the redness and swelling are obvious and the blisters are large and ruptured, you can use 30 grams of Sophora flavescens, 30 grams of Sanguisorba, 20 grams of Phellodendron, 15 grams of Chinese gallnuts, and 30 grams of Lithospermum chinensis, and boil them twice in water to make 500 ml. Apply cold compress for 15 to 20 minutes each time, once every 3 hours, and continue the treatment until the bullae dry up.

If the blisters are large and ruptured, strict sterility should be used whether or not lotion is used to prevent infection. When cleaning the skin after sunburn, it is best to use mildly acidic cleansing products that match the skin's pH value to avoid irritating the skin, such as using baby soap or soap-free baby shower gel to clean the skin.
