Description

Kyu-Ho Yi and colleagues describe, in 2026, a pilot treatment for sunken acne scars that combines gas injection with a collagen-stimulating filler. Atrophic scars form when inflammation destroys collagen and fibrous strands tether the skin down. Standard subcision cuts those strands with a needle but does little to rebuild the dermis.

Five patients received one session using a temperature-controlled device that delivered short bursts of carbon dioxide gas into the deep skin through a fine needle, together with a PDLLA filler product. Gas pressure freed the tethered bands while raised carbon dioxide levels were expected to stimulate blood flow and collagen cells. Photographs at two and four weeks showed qualitative improvement in scar depth and contour, and satisfaction scores were high. Only brief redness and swelling appeared.
