Different types of scar removal machine(2)

There is also a PDL（scar removal machine), also known as pulsed dye laser, 585 and 595. This laser is also mainly used to seal blood vessels.

There is also the most common dot matrix laser(scar removal machine). In fact, it is a carbon dioxide laser. Dot matrix is only one of its modes. Its function is to gasify the scar and make the scar smooth and shrink.

Others(scar removal machine) include ion beam, soft ray, photodynamic and many other equipment, which belong to photoelectric equipment. The main function of these devices is to close blood vessels, rearrange collagen in scar tissue and promote fibroblast apoptosis.

It should be noted that the single use of a scar removal machine often can not control the recurrence of keloids, so the current keloid treatment is to use two or more devices for combined treatment. Only in this way can keloids be cured without recurrence.
