Recollagenation of acne scars
1Division of Otolaryngology/Head and Neck Surgery, UCLA School of Medicine, USA.
Background:
Depressed acne scars remain a difficult problem to correct with present methods.
Objective:
A new process to restore the dermal thickness destroyed by acne inflammation, called recollagenation, was developed.
Methods:
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.
Results:
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.
Conclusion:
Recollagenation is an effective method to repair acne lesions.
