Abstract
BACKGROUND:
Despite their prevalence, there is a paucity of information in the medical literature on the treatment of atrophic chickenpox scars.
OBJECTIVE:
To evaluate the efficacy and safety of using the chemical reconstruction of skin scar technique for the treatment of atrophic facial chickenpox scars.
METHODS AND MATERIALS:
One hundred patients (mean age 23 years; Fitzpatrick skin types II-IV) were treated with focal chemical peeling with 70% trichloroacetic acid (TCA) for a maximum of six sessions. Improvement rate, frequency of adverse events and patient satisfaction were assessed.
RESULTS:
Five hundred thirty-three peeling sessions in 100 consecutive patients were performed. Final assessment at 12-week follow-up visit after the last treatment revealed improvement in 95% of patients: mild improvement in 12 cases, moderate improvement in 42 cases, and marked improvement in 41 cases. The appearance of scars did not change in five patients. Seventy-nine patients expressed moderate to high satisfaction with the results. Post-treatment side effects were mild and transient, resolving gradually within the study period.
CONCLUSION:
Focal peeling with high-concentration TCA appears to be a safe and effective alternative in the treatment of atrophic facial chickenpox scars.
