The Difference between Fractional Laser and Pixel Laser

To most people who often focus on beauty industry, fractional laser and pixel laser can never be two strange words. These two technologies all derive from USA. Nowadays, both of them, especially the former one, become the latest and most popular beauty technologies around the world. However, I would like to ask a all of you a question: Do you know the difference between fractional laser and pixel laser? The most possible answer may be : No. That’s ok. In the following text, I will unveil the answer step by step.

       Before talking about their difference, I want to introduce the similarity of them at first. Firstly, they have same treatment scopes. Both of them can cure the following diseases: wrinkles, cutis laxa, acne, scars, stretch marks etc. Secondly, during the treatment, their target tissue is both water in our skin. Thirdly, all of them will cause tiny thermal channels on the surface of the treatment parts. Around these tiny channels,it has a certain amount of ablative effect and thermal effect which will promote the collagen-shrinkage and collagen-rebirth.

       From the introduction in the former paragraph, we have got that it really exists many commonalities between them. But do not forget our task today: find the difference between fractional laser and pixel laser. Now let us make a study on it together.

       As we all know, before the treatment, we must choose the spot density in advance. After the preparation, the focal spots of both will be all outputted in a scanning mode. But the most important difference between them is just the scanning mode. During the treatment, the fractional laser output its focal spots one by one in an unordered way. That means it emits only one focal spot in one scanning, and after one scanning finished, the next scanning will not appear in the neighboring place of the former one. About pixel laser, all of its focal spots are outputted together. For example, if you set the spot density on the screen as 120, then the pixel laser will output 120 spots on the skin of the people being treated in one scanning.

       Till now, we have got a general understanding on the difference between them. But what different effects will be brought by these two different scanning modes? In the scanning mode of fractional laser, it can offer a longer rest period to our skin. Thus, the damage caused by heating will be reduced dramatically. In the scanning mode of pixel laser, a large amount of heat will act on skin at the same time. As a result, it may lead to thermal injury in the process of healing. According to this theory, the fractional laser is safer than the pixel ones. After the treatment, the reparative phase of the fractional laser will be much shorter than the pixel’s. Now, you must know the difference between fractional laser and pixel laser well. When you want to buy one laser machine next time, you can make your own decision properly and quickly.
