In hot summer, it is a big test for skin. The hot sun may Tan the skin and even leave sunburn. How to prevent sunscreen and remove sunburn? Unlike being able to whiten back after a period of time after tanning, sunburn generally does not subside automatically and is likely to be 'permanently retained', which is undoubtedly very damaging to the face. Let's have a look at how to prevent sunburn and let the skin spend the summer safely.
Cause analysis of sunburn
Why does sunburn come from? First of all, as the name implies, because of intense sunlight, subcutaneous pigment cells are stimulated, become very active, secrete a lot of melanin. If the skin tissue is not repaired normally after sunburn, the melanin is difficult to discharge normally, and gradually deposit to the dermis, and finally form sunburn. Of course, it's also about metabolism. Generally speaking, old people are more likely to have sunburn than young people.
In addition, improper use of skin care products and make-up can also accelerate the formation of sunburn. Some skin care products contain too much perfume, lead, mercury and other light absorbing ingredients. If it is used for a long time, it is easy to form sunburn when exposed to the sun. Moreover, some mm in order to acne, oil control or whitening, excessive exfoliation, the use of salicylic acid containing products, the skin becomes fragile and sensitive, difficult to resist the invasion of ultraviolet rays, after the sun may appear red rash, sunburn.
The sun spot is red oval at the beginning, and some may be slightly prominent. After a few days, it developed into irregular plaques of different sizes and depths. Sunburn often occurs in the face and neck, back of hand, upper and lower limbs. Moreover, relatively speaking, the facial sunburn is more obvious.
Prevention and treatment of fair bloom
In order to keep the skin white and bright, especially prevent sunburn in summer. There is no doubt that the most important thing is, of course, sun protection. Although this is a year-round, indoor and outdoor (indoor lighting will also affect the skin), all need to do homework. But in summer, we should pay more attention to sunscreen, including the sun protection index of sunscreen products should not be low, and it is better to keep SPF30 around; if you need to go out or expose to the hot sun, you should apply sunscreen every few hours, and you'd better take sunshade umbrella and sunshade hat with you; do skin repair and calm care in time after sunburn.
The prevention and desalination of sunburn can not be separated from oral and external use. Vitamin C and vitamin E can inhibit the formation and deposition of melanin. It is effective to whiten and spot by taking vitamin C, drinking lemon juice rich in vitamin E, and adding vitamin A to the mask.
For the formed sunburn, if you want to completely remove, you can use laser skin treatment. The wavelength released by laser is absorbed by melanin particles in the skin, resulting in the explosion and decomposition of melanin particles. And melanin particles mainly exist in melanocytes, so the wavelength of laser is rarely absorbed by other parts of skin tissue, which will not cause damage to the skin at the same time of freckle removal. The treatment time of laser freckle removal is about 10 minutes each time. After treatment, daily skin care and make-up can be carried out as usual, which will not affect normal life and work, and there is no need for recovery period, and there will be no adverse reactions or side effects. General treatment 3-5 times can be significantly effective.
Tips for preventing sunburn
1, through the freckle cream, whitening mask and other lifestyle beauty, it is very difficult to completely remove the sunburn. In the market, there are many statements about "peeling and freckle removing" and "bleaching and freckle removing". The effect may be obvious in a short period of time, but this method will only damage the skin tissue and damage the sebum membrane. The immunity and health of the skin are weakened, and it is more likely to produce sunburn or other effects when exposed to the sun and other external influences.
2. The formation of sunburn is closely related to body function. Reasonable diet, work and rest habits, help to regulate endocrine function. At the same time, ensure appropriate exercise, or massage, push lymph, promote blood circulation and metabolism, promote the metabolism and discharge of melanin in skin tissue, play the role of prevention and desalination of sunburn, and restore skin whiteness.
