Everyone was excited when they heard "Smashing Melanin". Hold for now, okay? Let me briefly talk about the principle of laser and the classification of whitening laser. Otherwise, you just think that the laser is just a few clicks and then the skin will be white. Possible benefits and risks~~~
Introduction to the principle of laser whitening
Laser in English is Laser (Light Amplification by Stimulated Emission of Radiation), the inventor of its principle is the famous Einstein , but the craziest and most regrettable thing about Einstein is that his ideas are really too crazy, so crazy that at that time there was no way to do experiments to confirm his principles! Therefore, although the theory of laser was proposed in 1917, and Einstein himself lived until 1955, in fact, the laser was not successfully manufactured until 1958. In other words, he invented something that he couldn't see in his life. It's really too tragic! But after the laser was actually verified, related applications and research began to be produced in large numbers. Later, a bunch of follow-up research won the Nobel Prize. Einstein didn't know whether this would make him smile or die? I think it should be Smiling Jiuquan, after all, he has won the Nobel Prize, so let others get it.
Like all cutting-edge technologies, the initial application is often in the "defense and military field". The laser also startedIt was used for military purposes, but with the end of the Cold War between the United States and the Soviet Union, relevant knowledge and technology were gradually matured and released, and lasers began to be used in medical applications. Of course, people's heads move very fast. Human beings love beauty so much that they want to use everything for whitening. With such a miraculous new technology, of course it is used for whitening. Otherwise, what are you doing?
That's just right, the laser is a thing that can accurately attack specific substances, and it is really good at crushing pigment blocks. It's so easy to use!
For example, there is a piece of white paper on the table with some black spots on it. After has swept all over for one round, you will find that the black spots are particularly damaged because the black spots absorb a lot of energy . And the blank part is like nothing happened.
How will it be applied on the skin? ! How about it? !
The melanin produced by melanocytes in the basal layer will gradually move upwards, making you look black. If you forgot about the mechanism of this part, go back and review the article on melanin mechanism and whitening active ingredients.
Laser light can produce great destructive power on melanin tissue precisely and in a short time. But don't forget, its principle is "selective absorption of black", that is, the darker it will receive more energy, so when the melanin is destroyed, a certain amount of energy will be absorbed nearby, and of course the epidermis will also absorb a certain amount of energy.Part of the energy may be received, which is why some skin may feel red and swollen like a burn after laser treatment. Applying the same principle can also be used for hair removal and tattoo removal.
Please don’t order food from the doctor when you are having laser treatment. Some people think that the effect will be better if the energy is stronger. But if you understand the above principles, you will know that the darker the skin, the energy should be lowered. Otherwise, the epidermis will cause serious thermal damage. This is a medical behavior, don't think that this is ordering a large cup of rare milk with light sugar to go ice~[!--分页符--]
After understanding the working principle of laser whitening, the next step is to get to know the common types of whitening lasers!
(Forget it, the article is too long, I will talk about it next time)
The name of the general laser is to see what kind of material is excited by the laser. For example, ruby laser" is the laser produced by exciting a small amount of "chromium atoms" in ruby. There are many names in medical beauty that are random gimmicks taken by , but this one is a real ruby~
Common Q&A for laser whitening and blemishes
Q1: Who is suitable for laser whitening?
A1: Basically, for dull skin, spots, or enlarged pores, different types of lasers will have different effects. So I will not say "Who are suitable for laser whitening", this is a choice, as long as you understand the effect of laser, possible side effects, consider the price and other factors, most people can use laser whitening.
A2: Pregnant women, people taking anticoagulants (not easy to clot), people with light-sensitive drugs, and people with diabetes (wounds are not easy to heal), or crab Foot swelling (Keloid may occur once a wound occurs, and laser is usually not recommended)
A3: In the first three weeks, avoid taking oral A acid or light-sensitive drugs. Avoid using acids for peels. Do not use physical exfoliants, and pay attention to sun protection. The main purpose is to prevent the skin from being too fragile before receiving the laser, or increase the risk of anti-darkness.
A4: Generally, the general full face laser treatment takes about 5-10 minutes. However, the areas and ranges to be treated vary from person to person. In addition, if some people are afraid of pain and need to apply anesthesia, remove the anesthesia, and add some cleaning time after the operation, usually one hour is enough.
A5: The pain level of each model is different, and each person's pain tolerance is also different. Usually whitening laser pain is not high, and many people can do without anesthesia. The most commonly heard description is the feeling of being gently bounced on the face by a rubber band.
A6: Generally, after whitening laser treatment, there will usually be slight sunburn, slight fever, and skin redness. If some plaques are treated at the same time, there may be a little bleeding in particular. The way of care varies according to the degree of your treatment. You should ask your doctor to explain the way of care to you. Some people will need some medicines after surgery, but not everyone. After surgery, sunscreen and moisturizer are essential. Use sunscreen products with at least SPF30 or above for sun protection. You can also eat more fruits and vegetables to supplement vitamin C to strengthen the effect of diluting melanin. Avoid alcoholic beverages and spicy food within a month, and avoid hot springs, saunas, and strenuous exercise that can easily cause skin redness. A small number of people may experience anti-blackness after the operation, and most of the symptoms will fade within six months. If this is the case, please contact your physician.
A7: In fact, there is no "immediate effect" after laser treatment, and a recovery period of several days is usually required. Of course, some lasers are relatively weak, and there is almost no recovery period, and the skin will become smoother soon. For example, some skin cleansing or compact powder lasers focus on applying makeup immediately after surgery. In fact, there will be no wounds after the treatment, and there will be fewer fine hairs on the face, so it will be easier to apply makeup. If it is to remove spots, it will often cause a little bleeding, and the recovery period will be longer. Regarding the recovery period and the degree of injection, you must communicate with the doctor before the operation!
A8: Everyone's skin type and degree of treatment are different, so it is difficult to have a certain standard. usuallyTo be conservative, an interval of more than one month is recommended. Be careful if the clinic asks you to call two or three times a month very frequently. Basically, a regular doctor will not ask you to do this. If you beat it too frequently, if the melanoblasts are killed and white spots occur, the loss outweighs the gain. For the actual treatment interval, please communicate with your doctor, and it is usually recommended to be more than one month.
Finally and finally, please know that laser is really a great invention. It's the cheapest and smartest way to do it. If you have a very urgent need, such as a wedding dress in two weeks, and you want to quickly whiten your skin, laser treatment may be a good choice. We also have to admit that it is really cool and tempting to directly use laser to crush melanin, but we must pay attention to communicate with the doctor, and don't watch TV shopping for how much the laser costs a few times. Don't forget, the essence of medical aesthetics is still medicine. Laser is a treatment method, and diagnosis is necessary before treatment. You watch TV shopping, and you prescribe treatment without diagnosing the condition at all. Under such circumstances, do you think you have a chance to get the most suitable treatment for you? This is worth thinking about together.
