The effectiveness of the treatment is related to three factors: the treating physician, the treatment equipment and the response to the laser treatment. In the treatment process, the main body of treatment is the physician, the physician’s degree of grasp of the condition, treatment experience is very important. Some people mistakenly believe that as long as they have the equipment, they can achieve good results, which is not true. Let’s say that the effect of the same camera is different from the photo taken by different photographers. Similarly, the same treatment equipment used by different physicians, the effect will be different, after all, the treatment equipment is only a tool used by physicians for treatment. At present, some small medical units have blindly introduced some equipment to do treatment, so we recommend that you do not blindly choose a hospital for treatment. When we buy big items, we tend to go to big shopping malls in order to ensure the quality of the goods, because it is more guaranteed. It is also better to choose a regular and good hospital for treatment, because these hospitals have stronger technical strength, better mastery of new medical equipment, and more importantly, a strong medical foundation, high medical reputation, clear diagnosis of the disease, and therefore “allopathic treatment”, and therefore more reliable application of new technologies. Of course, first-class treatment equipment is also very important, otherwise “a clever woman can not cook without rice”. Because the efficacy also depends on the quality of the equipment itself, the efficacy of different equipment of course also differs. Specialized hospitals and large medical institutions have better knowledge of medical equipment when purchasing medical equipment, and have authority in the purchase of medical equipment, usually the equipment purchased is the most advanced at the time, to ensure their own medical image and medical reputation, as well as their absolute leading position in the medical. Some medical units for various reasons, the equipment purchased is generally lower in price and poorer in grade (such as the same equipment imported from the United States, although some are very similar in appearance, but the internal character and quality varies greatly), which of course will affect the treatment effect. The last thing to emphasize is the issue of individual patient responsiveness to laser treatment. Just as the results of treating different patients with the same medication for the common cold vary greatly, so does the efficacy of the same physician, using the same treatment equipment, treating different patients. This is because there is a great difference between people, as shown by the different responsiveness to light therapy. Therefore, you may see some patients with very good results that you envy, while others have slow results that make you feel overwhelmed, which is normal. In fact, those patients who do not show significant results at the beginning will also show happy results after a few more treatments. In general, the color of the skin and the reactivity of the skin to the laser are important factors in the results of the treatment.
