Acne Scars

Introduction: Pulsed carbon dioxide laser devices are considered highly effective treatment options for skin resurfacing.  The aim of this study was to evaluate the efficacy and safety of an ablative 10,600-nm carbon dioxide fractional laser system on moderate to severe acne scarsMaterials and Methods: Forty participants (Fitzpatrick skin types III–IV) ranging from the age group of 25-45 who had moderate to severe acne scars were included in the study.CO2 Fractional laser was used, Unit: eCO2 Lutronic Korea; FDA approved, in 3 sessions at one month interval and 4th and 5th sessions at the interval of 2 months. Comparison was done on a monthly basis for the improvement of scars at one monthly interval and any other symptoms like pain, recovery time for wound healing and complications of laser like hyperpigmentation were noted by asking the patient to fill up a questionaire.Results: All the patients completed the treatment.At the end of the session participants experienced a reduction in the size of the scars. At the first laser session, they presented 10-25%, at the second session 20-45% and at the third session 30-60%. All participants felt an ascending improvement rate during and after the course of treatment. An average improvement of 71% was observed. Twelve of sixteen patients showed mild erythema which was transient and recovered at its own.Conclusions: Fractional Co2 laser ablation provides a safe and effective treatment of moderate to severe facial acne.

Spectroscopic Instrumentation

The spectral line parameters of carbon dioxide have been measured in the laser band I (00011 ← 10001) centred at 10.4 μm. The spectra were recorded at room temperature using the spectroscopic instrumentation at the far-infrared beamline, Canadian Light Source, Saskatoon, Sask. The spectral line intensities, air- and self- broadened Lorentz half widths, and pressure-induced shift coefficients were retrieved for 48 spectral lines using a multispectrum fit technique (Benner et al. J. Quant. Spectrosc. Radiat. Transfer, 53, 705 (1995)). Line parameters were retrieved using the Voigt and speed-dependent Voigt models. The deviations between our results and other results reported in the literature and in the HITRAN08 (Rothman et al. J. Quant. Spectrosc. Radiat. Transfer, 110, 533 (2009)) database were examined and discussed. The effect of errors in fitting channel spectra parameters was examined and found to be mitigated by the inclusion of channels in the multispectral fit.
