What is the process of laser mole removal and what instrument is used?

Laser nevus removal is to use the huge energy of laser to act on the pigment tissue in an instant, so that the pigment is crushed, decomposed and swallowed by macrophages and excreted with lymphatic circulation, thus achieving the purpose of removing pigment.

When removing nevus by laser, we can hear the tiny explosion and see the dry fragments of nevus tissue protein when gasifying tissue. Every gasification 1 time, the surface debris must be wiped with normal saline, cotton swab or gauze to avoid unnecessary thermal damage during repeated scanning. Gasification to black basically disappeared, and the following signs were observed by naked eyes: rough skin appendages were seen at facial wounds, which were white particles, and most of these granular tissues were sebaceous glands; For example, dense connective tissue can be seen in the wound of limbs or trunk, and the density of tissue gradually decreases from dermal papilla to deep tissue. When the gasification continues, the attachments in the dermis disappear, the tissue density becomes low, and thick fiber bundles can be seen, which looks like cotton thread immersed in water. At this point, it has reached the reticular layer of dermis, and gasification should stop. At this time, if filamentous melanin or punctate melanin still extends deep, VersaPulseQ switch can be used with 75nm or 1.

064nm laser was used for treatment, the spot was 2-3mm, the energy was 4-8J/cm2, and the pulse was repeated several times locally.
