Often people with acne can be left with permanent depressed scars. Trauma or surgery can also leave depressed or indented scars. Recently Laser has become the approach to improving depressed scars. Either a single session with a carbon dioxide laser which will result in days of downtime and potential months of redness or multiple treatments with non-ablative lasers can improve scars. Available lasers include Fraxel Co2, fraxel erbium, and Nd Yag lasers. The nd yag has no downtime and results in permanent improvement of 35-40 per cent. The fraxel erbium does leave days of redness and results in up to 50 per cent improvement. The treatments are more expensive costing about 4-5,000 for a series of treatments versus 1,250 for yag. Combining yag with a long term filler such as Artefill can give a significant long term improvement at a lower cost than Fraxel.
