What exactly is fractional laser? To many patients, it appears to be very "high-end." The widespread popularity of many treatments is often inseparable from the deliberate promotion by beauty institutions. However, "fractional laser" is not as mysterious as it seems. I believe everyone has seen a wire mesh; the light emitted by the fractional laser is arranged in a grid pattern, with the corresponding mesh parts lacking laser beams. This means it does not affect the entire skin surface, leading to a much faster skin recovery rate post-treatment.

Fractional laser works by emitting hair-thin laser beams in a grid pattern on the skin, creating numerous micro-injuries. These beams penetrate the epidermis and reach the dermis, stimulating and damaging the skin to promote regeneration, ultimately achieving the effect of skin structure reconstruction.

Characteristics: Compared to traditional laser treatments, it has a broader clinical application range, longer-lasting effects, and faster skin recovery. This is why you often see the scabs on the skin of someone who has undergone fractional laser treatment arranged like a mesh. The difference between fractional laser and previous laser treatments is that it does not affect the entire skin surface but works on the skin in a dispersed manner at specific intervals, allowing for quicker recovery while still achieving the desired therapeutic effects.

Types of Fractional Laser:

There are mainly two types based on the treatment method.

1. Ablative Fractional Laser: This method causes the skin to form scabs and results in significant skin damage. However, the effects are much more pronounced, and recovery typically takes 2-3 months. Common examples include CO2 fractional laser and erbium laser.

2. Non-Ablative Fractional Laser: This type is much gentler compared to the first one, with each treatment's laser energy being about one-third of that of ablative lasers. It does not cause scabbing, and the redness on the face gradually fades within 1 to 3 days post-treatment, having minimal impact on one's external appearance during the treatment period.

点阵激光 到底是一种什么样的东西呢？在很多患者的眼里它是那么的“高大上”，有很多东西之所以那么流行，其实与美容机构的刻意宣传是分不开的。“点阵激光”其实也不是那么神秘。我相信大家都见过铁丝网吧，点阵激光发出的光就是以结点的方式排列，而对应的网眼部分就是没有激光束的，也就是说它不作用于整个皮肤，所以后期皮肤的修复速度会快很多。

点阵激光是通过发射出细如发丝的激光，以点阵状落在皮肤上，先制造出无数个微小的伤口，然后穿透表皮，到达真皮，以刺激、破坏肌肤来让肌肤再生的方式，实现皮肤框架重建的效果。

特点：与传统的激光治疗相比，它具有临床使用范围更加广泛，效果持续长久、对皮肤的修复更快等特点。所以你经常会看到做了点阵激光的皮肤脸上如果结痂的话，痂皮的排列就像网眼一样。点阵激光打在皮肤上跟以往的激光的差别是它不用作用于整个皮肤，只是按照一定的间隔，分散的作用于皮肤，皮肤修复起来会比较快，并且同样可以达到治疗作用。

点阵激光的种类

以对皮肤的治疗方式来区分，主要有两种。

第一种剥脱性点阵激光，这种方式是会让皮肤结痂，对皮肤的损伤性要大许多，当然，效果也要好很多，恢复一般要2、3个月。常见的有二氧化碳点阵激光、铒激光。

第二种非剥落点阵激光。相对于第一种，要温和很多，一次治疗的激光能量是上一种的三分之一。并且不会结痂，术后1到3天脸部就会逐渐褪红，治疗期间对外在形象影响不大。
