A combination of 1064 nm Q-switched fractional ND-YAG laser with a nonfractional microsecond pulsed technology has a synergistic effect for nonablative facial rejuvenation
JOURNAL OF COSMETIC DERMATOLOGY(2021)
Abstract
Background: Non-ablative fractionated lasers for facial rejuvenation are increasingly preferred over ablative lasers due to their minimal downtime and fewer adverse events. The synergistic effect of the Q-switched fractional (QSF) 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, in combination with the non-fractional microsecond pulsed technology has yet to be fully evaluated. Aim: Our objective was to determine the safety and efficacy of this combination treatment for skin rejuvenation. Methods: Patients who underwent treatment using the QSF-Nd:YAG laser, followed by the non-fractional microsecond pulsed Nd:YAG were evaluated retrospectively using a novel 3D imaging modality for degree of facial erythema, wrinkles surface area, and wrinkle depth. Pain perception, adverse effects, and patient satisfaction were assessed at the 2-month post-treatment follow-up visit, graded on a scale of 1- 5 (1 = not satisfied, 5 = very satisfied). Results: Ten female patients' ages 44-67 (mean 55 years) completed both treatment and follow-up period, with an overall mild improvement in facial erythema and wrinkle surface area (mean improvement of 18% and 19.5% accordingly), as well as a mild improvement in overall wrinkle depth. Pain and adverse effects were mild and transient. Patients' satisfaction was high. Conclusion: The combination of the QSF-Nd:YAG laser and non-fractional microsecond pulsed technology, using a single Nd:YAG 1064 nm laser platform, was found safe and effective as a non-ablative modality for facial rejuvenation, as demonstrated by a novel 3D imaging modality.
