Will CO2 laser and subcision help reduce the appearance of my lip lift scar? 9 months post op

I have been performing subcisions routinely for elevating and smoothing all kinds of indented scars since 1995. It is a relatively inexpensive procedure that has a several decades" long track record for safety and efficacy in all skin types and engenders little to no significant post-treatment downtime. CO2 laser, on the other hand, is a relatively expensive and aggressive procedure (much like dermabrasion was) that runs the risk for development of scars and skin dyspigmentation. Buyer beware. On the other hand, once the subcision is performed, professionally perfomred manual Dermastamp microneedling (no need for the added expense or risks of RF microneedling) can be performed to help the site blend better with the surrounding normal tissue. You would be wise to consult with an experienced, board certified cosmetic dermatologist. Hope this helps and best of luck .
