Acne Successfully Treated with Laser Combination

Dermatolog Surg; ePub 2018 Jun 5; Bakus, et al

Active acne can be treated successfully with a combination of long-pulsed (LP) and Q-switched (QS) YAG lasers with patients remaining off acne medications throughout laser therapy and the follow-up period, according to a recent study. 20 patients with moderate-to-severe inflammatory acne were treated with LP YAG laser followed immediately with QS YAG laser. Patients received at least 8 treatments. Follow-up evaluation occurred at a minimum of 12 months. Pre- and post-treatment photographs were graded by blinded physicians. All topical acne medications and oral antibiotics were discontinued throughout the therapy and follow-up period. Researchers found:

  • There was an 81% reduction in acne lesions, with 60% of patients having ≥90% reduction.
  • Overall appearance was graded at 84% improvement at follow-up.
  • Follow-up occurred at a mean of 22.7 months after completion of therapy.
  • Aside from transient erythema, there were no other adverse effects.
