“…Edema, bruising and pain can occur at the injection site, and adverse effects like ptosis, muscle weakness and headache have been reported [13]. Recently, an MFR device was developed, a novel and promising tool for facial rejuvenation [4]. Therefore, the aim of our study was to compare the effects of BoNT/A injection and MFR treatment on periorbital static wrinkles and lines.…”

“…Lee et al [4] reported that PIH appeared in 40% (nonablative) and 92% (ablative) of patients who received fractional photothermolysis treatments. In our study, two patients (22.2%) reported PIH on the MFR treatment side which resolved spontaneously within 2 months.…”

“…Several therapeutic modalities have been utilized for periorbital rejuvenation, including surgery, chemical peeling, botulinum toxin or filler injection and various laser devices [2,3,4,5,6,7,8,9]. Multiple intradermal injections of botulinum toxin A (BoNT/A) are known to improve both static wrinkles and lines as well as dynamic wrinkles [1].…”

Comparison of Microneedle Fractional Radiofrequency Therapy with Intradermal Botulinum Toxin A Injection for Periorbital Rejuvenation

Background: For periorbital rejuvenation, injection of botulinum toxin A (BoNT/A) is known to improve both static as well as dynamic wrinkles. A microneedle fractional radiofrequency (MFR) device was recently developed and is a novel and promising tool. Objective: This study compares the effects of these two treatment modalities on periorbital static wrinkles and lines. Methods: Twelve healthy women aged 20-59 years with periorbital wrinkles participated in this study. Each patient received one session of intradermal injection of BoNT/A on the left periorbital area and three sessions of MFR on the right. Clinical improvement, skin elasticity and subjective satisfaction were evaluated at every visit (baseline, 3, 6 and 18 weeks). Results: BoNT/A injection showed superior effects at 3 and 6 weeks. However, the MFR device showed better improvement at 18 weeks. In skin biopsies, the expression of procollagen 3 and elastin was increased on the MFR side compared to the untreated skin and the BoNT/A injection side. The patient satisfaction surveys at 3 weeks showed better satisfaction on the BoNT/A treatment side compared to the MFR treatment side. At 18 weeks, there were no significant differences in patient satisfaction between the two sides. Conclusion: BoNT/A injection rapidly improved periorbital wrinkles, but the effect decreased up to week 18. Compared to BoNT/A injection, MFR therapy showed gradual and long-term improvement in periorbital rejuvenation.

Lasers and light-based therapies in ethnic skin: treatment options and recommendations for Fitzpatrick skin types V and VI

SummaryEthnic skin or 'skin of colour', which is characterized by increased epidermal melanin, labile melanocytes and reactive fibroblast responses, poses special challenges for the use of laser and light-based therapies. These therapies are associated with a greater risk of dyspigmentation and scarring in ethnic skin and therefore require careful selection of device and treatment parameters to minimize complications. Whereas early-generation lasers for hair removal and resurfacing were generally contraindicated for individuals with Fitzpatrick skin phototypes (SPT) IV-VI, advances in the past decade have given rise to a range of devices that can be safely used in ethnic skin. Longer wavelength lasers such as the 810 and 1064 nm Nd:YAG; intense pulsed light and monochromatic excimer light (308 nm); fractional lasers; and radiofrequency devices have all been used safely for hair removal, pigmentary abnormalities, resurfacing and skin tightening in ethnic skin, respectively. Notwithstanding these advances, nuances in the laser or light treatment of darker skin types remain and must be considered to ensure safe therapeutic outcomes. The vast majority of published data pertaining to lasers and light treatments in nonwhite skin involve patients of East Asian ethnicity (e.g. Korean, Japanese, Chinese, Thai). By contrast, there is a paucity of studies involving individuals of African ancestry or those with SPT V or VI. This article will review laser and light-based modalities that are considered safe and effective for individuals with richly pigmented skin. What's already known about this topic?• Published data or recommendations on the safe and effective use of lasers in Fitzpatrick skin phototypes (SPT) V and VI are limited. What does this study add?• This review addresses knowledge and practice gaps by summarizing available data on the use of lasers in patients with SPT V and VI, a subset of the population in which the risk of iatrogenic pigmentary and scarring complications is highest.• This provides clinicians with practical knowledge of which devices have been studied in SPT V and VI and offers treatment recommendations to improve outcomes.Traditionally, the literature on cosmetic procedures, especially laser and light-based therapies, has focused on the treatment of individuals of European ancestry with Fitzpatrick skin phototypes (SPT) I-III. Safety limitations of first-generation technologies as well as socioeconomic, demographic and cultural factors may contribute to the relative lack of studies involving the various racial/ethnic groups with constitutively darker skin. Shifts in the aforementioned contributing factors have led to considerable increases in the performance of cosmetic procedures in nonwhite racial/ethnic groups. According

Skin rejuvenation is a common request among patients and a strong driver for the development of new, energy-based devices in dermatology. Various procedures exist for skin rejuvenation. Patients prefer methods of skin rejuvenation with few sessions, minimal downtime, no adverse events, and lasting results. Extensive research has been conducted on radiofrequency (RF)-based skin tightening due to its noninvasive, tolerable, and effective mechanism. Different RF technologies directed toward skin rejuvenation exist. Effective treatment and skin rejuvenation have been achieved with RF technologies, but more potential exists in combination treatments which can be adjusted for patients according to specific skin types, skin conditions, and patients' preferences. In this review, we discuss eight RF-based protocols directed toward skin rejuvenation. These treatment combinations can be applied in any dermatology clinic and can lead to excellent results with highly satisfied patients.
