Abstract
Depressed acne scars remain a difficult problem to correct with present methods. A new process to restore the dermal thickness destroyed by acne inflammation, called recollagenation, was developed. After an intradermal pocket was created at each depressed site, an implant of freeze-dried, irradiated, human cadaver fascia lata was inserted through a needle hole to elevate the depressed epidermis. Selected sites were retreated to establish the desired dermal topography. Initially, local inflammation created an elevated phlegmon at the treatment site, which then progressively leveled over the subsequent 4-10 weeks. Ultimately, a predictable improvement in skin contour occurred in the majority of depressions. Recollagenation is an effective method to repair acne lesions.
