Scar revision is a process of cutting the scar tissue out. After the excision, the new wound is usually closed up to heal by [[primary intention]], instead of [[secondary intention]]. Deeper cuts need a multilayered closure to heal optimally, otherwise depressed or dented scars can result.<ref name=scarrevision2010>{{Cite web  | title = Scar revisions  | quote = Deep cuts need multi-layered closure to heal optimally; otherwise, depressed or dented scars can result  | url = http://www.haplasticsurgery.com/scar-revision-surgery-dallas-texas.html  | access-date = 16 October 2010  | archive-url = https://web.archive.org/web/20120119050557/http://www.haplasticsurgery.com/scar-revision-surgery-dallas-texas.html  | archive-date = 19 January 2012  | url-status = dead  | df = dmy-all  }}</ref>

Surgical excision of hypertrophic or keloid scars is often associated to other methods, such as pressotherapy or silicone gel sheeting. Lone excision of keloid scars, however, shows a recurrence rate close to 45%. A clinical study is currently ongoing to assess the benefits of a treatment combining surgery and laser-assisted healing in hypertrophic or keloid scars.

''Subcision'' is a process used to treat deep rolling scars left behind by [[Acne vulgaris|acne]] or other skin diseases. It is also used to lessen the appearance of severe [[glabella]] lines, though its effectiveness in this application is debatable. Essentially the process involves separating the skin tissue in the affected area from the deeper scar tissue. This allows the blood to pool under the affected area, eventually causing the deep rolling scar to level off with the rest of the skin area. Once the skin has leveled, treatments such as [[laser resurfacing]], [[microdermabrasion]] or [[chemical peel]]s can be used to smooth out the scarred tissue.<ref>{{Cite web|date=2014-09-17|title=Chemical peels vs laser peels vs microdermabrasion: which one is right for you?|url=https://www.bclaserandskincare.com/2014/09/lasers-chemical-peels/|access-date=2021-06-24|website=Beautiful Canadian Laser and Skincare Clinic|language=en-CA}}</ref>
