Entering the summer, the heat wave is rolling, the light is strong, although the appropriate sunlight is beneficial to the human body, but excessive or long-term exposure to the scorching sun will accelerate skin aging, and serious skin diseases will be induced. How to protect yourself from the sun in hot summer?
Let's first understand what sunscreen is to prevent? What skin problems can be caused by prolonged UV exposure?
The ultraviolet rays in the sun are divided into three bands, of which UVA and UVB can penetrate the atmosphere and reach the dermis and epidermal base layer of human skin, respectively. What we usually say is sunscreen, which is to prevent UVA and UVB these two ultraviolet rays.
The first is that we have an acute sunburn situation, then acute sunburn means that after we get sunburned, there will be very serious skin redness, and even a large number of blisters, and the burning pain of patients is very serious.
In addition, prolonged sun exposure can even cause something like what we clinically call pleomorphic sun rash, which is a variety of itchy rashes on our skin.
This rash even after the end of the year, every year with UV time will attack, to the patient has a very serious skin impact, but also caused a serious impact on the quality of life.
What is the difference between physical sunscreen and Chemical sunscreen?
Medical staff also introduced that according to the different ingredients of sunscreen, sunscreen is divided into physical sunscreen, physical and chemical sunscreen and chemical sunscreen. How are they different? Which sun protection works best?
Physical sunscreen is mainly the composition of titanium dioxide and zinc oxide, chemical sunscreen it is mainly through the absorption of ultraviolet light, component conversion, to offset the effect of ultraviolet light on skin damage, physical and chemical mixed sunscreen is both.
Medical staff suggest that when applying sun protection, different types of sun protection products can be selected for different groups of people, especially children, and be careful when choosing sun protection products.
In the daylight environment, patients with more sensitive skin choose pure physical sunscreen. The advantage of chemical sunscreen is that it is relatively light in texture, and the skin's stickiness will be weak after being applied, and the skin will feel better.
Most people who are not sensitive or convenient to reapply sunscreen products can choose physical and chemical mixture or chemical sunscreen, which can achieve better use effects and user feelings. We recommend that children under 6 months of age or to cover the sun protection, then in 6 months to more than 2 years of age can choose children's sunscreen products.
Skin has a certain tolerance does not need to "fully armed" hard sunscreen
With the continuous high temperature weather, a variety of sunscreen equipment has become a different landscape. Colorful sunscreen coat, sunscreen mask, sunscreen ice sleeve, sunscreen gloves, many people in order to sunscreen, as long as exposed to the use of this hard sunscreen way, the body from head to toe wrapped tightly. So, is this sun protection really what we need?
For example, we are now on holiday, many patients are learning to drive in driving schools or staying outdoors for a long time, hard sun protection can indeed achieve very, very good sun protection effect.
If we are just commuting to and from work, we are within half an hour, or the UV exposure index of the day, for example, 2 to 3, a low or medium intensity UV exposure, in fact, the skin can tolerate about 20 minutes of sun exposure, or we can wear light sunscreen products.
Strict hard sun protection is not necessary in these environments, and may also inconvenience our lives.Tan tan red peeling blister how to deal with correctly?
Summer scorching sun, if a long time exposure to the sun, light tan tan red, heavy peeling blister, then how to do this situation?
Medical staff suggest that after accidentally sunburn in summer, wrap ice cubes in a towel as soon as possible for cold compress, but be careful not to let the skin contact the ice directly.
In addition, you can choose a low-sensitivity moisturizer, but it is recommended to use 24-48 hours later, to minimize the friction between clothing and skin. Skin repair usually takes up to four weeks, and when you have to go outside, try not to apply sunscreen to the affected area.
If the local skin is red and hot after sunlight irradiation, and there is no blister, then the method of cold wet compress may be able to relieve it. If it hurts very much, you may take a little pain medication yourself, but if the symptoms are obvious or even bullous, you should seek medical attention in time.
