Fractional CO2 Laser resurfacing treatment of acne scar comparing high and low energy levels

Background : Fractional CO2 laser resurfacing in the treatment of acne scars, attempts to reduce adverse effect by creating microscopic injury zones dermis with skipped interval areas. Aim study The purpose this is compare safety and efficacy high pulse energy (70 mJ) low (45 fractional facial scars. Patients Methods Twenty patients moderate severe atrophic scars were treated three sessions at four-week intervals levels applied each side face separately. severity baseline after was assessed using Goodman Baron’s qualitative scar grading system. Patient satisfaction score obtained a quartile scale. Results on both sides comparable other before (p = 0.643). At final assessment, demonstrated an excellent response 0.000). However, difference between mean scores not significant 0.731). most frequently reported effects crustation erythema. Crustation lasted longer right (mean 6.75 days) whereas for left 5.45 days). Erythema transient only four cases persisted beyond week (right 10.5 days while 8.75 Conclusions Both mJ/pulse) results satisfactory outcomes no statistically differences. While duration (crustation erythema) increased slightly higher fluence.
