Biometric changes of skin parameters in using of microneedling fractional radiofrequency for skin tightening and rejuvenation facial

Abstract

Background: Fractional radiofrequency (RF) has been used for skin rejuvenation and tightening by dermatologists and cosmetic surgeons in recent years. Methods: Twenty female patients (mean age of 51.9 years) with Fitzpatrick III to VI skin phototypes who desired to undergo skin lift/tightening received six sessions of fractional microneedle RF treatment and were assessed at baseline and then 3 months after the last session for biometric characteristics using a Colorimeter, Visioface 1000D, Tewameter, Cutometer, Mexameter, and Sebumeter and a skin ultrasound imaging system to evaluate the transepidermal water loss (TEWL), skin pores, color, melanin content, erythema, sebaceous content, and thickness and density of the epidermis and dermis. Patient satisfaction with visual analog scale (VAS) was also measured. Results: The results showed that skin pores and spots decreased significantly. TEWL also decreased significantly (by 18.44%). Meanwhile, skin density increased significantly (R7, by 44.41%). The ultrasonographic assessments showed that both the density and thickness of the dermis and epidermis were increased. The changes in the other parameters were not significant. Conclusion: FR increases the density and thickness of the dermis and thus also increases the collagen content and decreases skin pores and TEWL.

Characterization of skin aging through high‐frequency ultrasound imaging as a technique for evaluating the effectiveness of anti‐aging products and procedures: A review

“…This analysis indicates that when using the HFUS technique for this purpose, antiaging treatments are expected to promote increased dermal echogenicity, which in turn is related to increased collagen content and dermal redensification. 48 Crisan et al (2015) showed that topically applied vitamin C is highly efficient as a rejuvenation therapy, inducing significant collagen synthesis in all age groups studied through the HFUS technique.…”

“…22 One of the anti-aging strategies used is the fractional radiofrequency (RF) procedure for skin rejuvenation performed by dermatologists and plastic surgeons. 48 In a study developed by…”

“…Ultrasound evaluations showed that both density and thickness of the dermis and epidermis increased; however, there was no control group in the trial. 48 Beijing, 84 participants between 25 and 65 years were divided into two groups and treated each of them with hyaluronic acid fillers, generated by different cross-linking technologies, which was monitored for 48 weeks. The hyaluronic acid materials of both could be detected and visualized using HFUS in the nasolabial fold region.…”

“…A aplicação de RF pode ser realizada entre uma ou em várias sessões, depende do dispositivo e dos indivíduos que irão receber o tratamento. Nilforoushzadeh et al, (2020) ideal, estimam-se, e devem estar em conformidade com a diversidade de protocolos, equipamentos terapêuticos e etnia de cada indivíduo (GORGU et al,2019).…”

Eficácia da radiofrequência e laser no envelhecimento cutâneo facial: uma revisão sistemática / Efficacy of radiofrequency and laser in facial skin aging: a systematic review

“…Journal of Health Review, Curitiba, v.4, n.6, p. 25606-25616 nov./dec. 2021(NILFOROUSHZADEH et al, 2020;SERDAR et al, 2019;ZHANG et al, 2018;GOLD et al, 2016). A literatura explica esses resultados por meio de achados histológicos, dado que, sendo minimamente invasiva, a radiofrequência microagulhada fornece corrente para a derme profunda e cria uma zona térmica controlada, reservando a epiderme.…”
