Brief Summary:
This study aimed to compare the safety and efficacy of subcision followed by diluted calcium hydroxyapatite injection versus subcision followed by the painting original chemical reconstruction of skin scars (CROSS) technique using trichloroacetic acid (TCA) for the treatment of atrophic acne scars.
Detailed Description:
Atrophic scars present as depressions secondary to fibrous contractions. Subcision is a technique in which a needle is inserted under the acne scar to sever the fibrous tissue (tethers) that bind down the scar. This releases the fibrous tissue.
The original chemical reconstruction of skin scars (CROSS) technique using trichloroacetic acid (TCA) entails focal application of highly concentrated TCA (70% to 100%) with firm pressure applied to the entire atrophic area using a sharpened wooden applicator until frosting occurs.
Fillers containing hyaluronic acid, calcium hydroxyapatite, and poly-L-lactic acid are increasingly used to correct atrophic acne scarring as they augment soft tissue in variable degree and are most effective in soft rolling or boxcar scars.
