Follicular cysts are caused by keratin trapped in a hair follicle, and they are often associated with swelling, inflammation, pain, and secondary infection. This laser procedure can ablate multiple layers of cysts and adjacent hair follicles with minimal bleeding and minimal thermal damage to the surrounding healthy tissue.

This laser benefit is especially prominent in delicate areas, such as eyelids.
