Dear bensterism,I often treat use a combination of subcision and dermal fillers for treatment of indented scars and I get great results. However, an-in person examination would be required to estimate which treatment would be the best for you. I would suggest you to consult a board-certified plastic surgeon.

Good Day,This is an excellent question and in my humble opinion, the best answer is in the photographs. Your facial scar is small. It is at a transition area between two body areas, which makes camouflage easier.Since the scar is indented, but with a small diameter. I recommend surgical excision with a dermal punch at each of the scar center points and closure with a suture (most likely one or two). This excision will treat the indentation without the need for other volume, such as fillers. When patients have indented linear scars, is best to excise them, undermine the skin, bring together the deep tissue (usually either fascia or muscle), and perform a plastic surgical closure.Post-treatment along the scar (or as primary treatment, which in this case is not the best option) with a skin resurfacing energy based system, CO2 laser or radio frequency (RF) followed by dermal needling (Micron better than Dermapen or Rejuvapen) and topical application of PRP. Also, post-treatment topically with either a silicone base scar cream. Alastin extra cellular matrix cream and human stem cell creams (Stemulation or Regency) that increases healing and improves the outcome.In summary, you have a scar that is more simply to treat than most and have many options to choose from to reach your desired result.
