The Use of Lasers (Ablative Laser, Non-ablative Laser, Fractional Laser, Photobiomodulation (PBM)) in Skin Regeneration

Abstract

Lasers have been used in a variety of industries, but we will concentrate on their use in medicine, specifically dermatology. I concentrated on three types of lasers in this article (ablation, non-ablative lasers, and fractional lasers). The non-ablative laser causes skin contraction as a result of wound stimulation of collagen during the healing phase in the dermis, upper dermis, and thermal ablation. Laser ablation is more dangerous because it heats up the dermis. A fractional laser affects the inner dermis layer, which contains collagen, rather than the epidermis, which stimulates this vital component. An ablative fractional laser, on the other hand, peels off the skin's outer layer. According to research, these three lasers produce unfavorable outcomes. Therefore, PBM technology was used without thermal interactions and effects on the skin, increasing patient satisfaction with rejuvenation. This is what we concluded through the search engines Scopus, Google Scholar, and the EndNote application.
