ABSTRACT
BACKGROUND:
Therapeutic dogma has been to treat acne scars with ablative fractional laser no less than 6 months after isotretinoin (ITN) cessation.OBJECTIVE:
To evaluate the safety and efficacy of fractional ablative CO2 laser (FACL) in patients treated concurrently with ITN.METHODS:
We conducted a prospective split-face randomized control trial in patients treated with FACL concurrently with ITN versus patients treated with FACL 6 months post-ITN treatment. Patients received 3 monthly sessions of FACL with concurrent ITN treatment on half of the face; the other side of the face received the same FACL treatment regimen 6 months post-ITN cessation. Patients were followed for adverse effects up to 6 months post-FACL treatment. Final cosmesis was scored using the Quantitative Global Acne Scarring Grading System (GASGS) by three independent dermatologists.RESULTS:
The GASGS of the concurrent ITN-FACL treated side of the face was significantly lower than the side treated with delayed laser therapy (4.7 ± 2.5 vs. 7.7 ± 2.9, respectively, p < 0.001).LIMITATIONS:
The laser's settings were standardized, and not adjusted per patient skin type.CONCLUSION:
Per our prospective trial, concurrent treatment of FACL -ITN is superior to delayed FACL treatment 6 months post-ITN cessation. Fractional ablative laser treatment is effective in improving acne scars, which persist despite isotretinoin therapy.Palavras-chave
