Filler or laser for hypertrophic scar? Artefill or Radiesse or some CO2 fractional laser to treat indented scar? (photos)

Thank you for your inquiry. For a relatively shallow scar like yours, you could certainly minimize or even eliminate the appearance without surgical excision. At our office, we offer microneedling with PRP, which is a minimally-invasive procedure that works with the body’s own healing process to smooth out minor imperfections like scarring. To further enhance your results, we can add injections of dermal fillers, which plump and smooth out the skin from the inside out. While the results of these treatments are temporary, they can last for many months before another treatment is needed. Of course, the best solution for you is to see an experienced plastic surgeon that offers a variety of treatments that can be customized to your precise situation. After a personal assessment, this professional will be able to recommend the best treatment option for you.

Looking at the photos, it's relatively well healed scar considering I see a full spectrum of different scars.  The redness can be improved with lasers.  Laser however can cause light induced hyper pigmentation so get treated by an expert as it can be a double edged sword.  Recently, micro needling with Radiofrequency (i.e. Infini) has become very effective in treating scars, and I would look into it as it is minimally invasive and often gives results much better than expected.  As there is no raised component of the scar, cortisteroid injection would not be indicated here.  Hope this helps.

Yes, a combination approach will give the most improvement for this type of scarring. This scar can be improved with a combination of lasers (Fraxel, Yellow, Co2), microneedling/prp, subcision and fillers. I recommend getting a formal evaluation with a scarring expert.  See an expert. Best, Dr. Emer

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. Daniel Barrett, MD, MHA, MS

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.
