Female Rejuvenation: Fractional Radiofrequency Versus Microneedling


In the phase of menopause, the dramatic decline in estrogen levels initiates a complex array of transformations in the skin, introducing noticeable shifts in texture and elasticity. Initially, a conspicuous surge in dryness is observed, succeeded by a discernible reduction in firmness and suppleness. These shifts are intricately linked to a decline in sebum production, collagen density, dermal thickness, and the integrity of elastin fibers.


Research suggests that within the initial five years post-menopause, the depletion of dermal collagen can escalate up to 30%, accompanied by an annual reduction of approximately 2.1%. Concurrently, skin thickness undergoes a yearly decrease of 1.1%. These alterations wield a significant impact on the aging process, influencing the overall aesthetic and health aspects of the skin.


Beyond the visible implications on the skin, the repercussions of menopausal transitions extend to the female genital region, encompassing issues like vaginal dryness, pruritus, dyspareunia, discomfort, burning sensations, dysuria, and an elevated susceptibility to genitourinary infections. Consequently, women experience a direct influence on their overall well-being and quality of life, with a notable emphasis on the intimate and sensitive nature of these changes, including an observable increase in the laxity of external genitalia.


Diverse therapeutic strategies have emerged to counteract or alleviate these menopause-related changes, spanning systemic and topical treatments, surgical interventions, and more recent non-invasive procedures targeting the enhancement of genital skin appearance. However, challenges such as the inherent risks and costs associated with surgical procedures, along with contraindications linked to hormone replacement therapy, underscore the imperative for innovative and non-invasive therapeutic alternatives.


Among the burgeoning treatment modalities are laser therapies, including fractional CO2 or erbium (Er: YAG), Radio Frequency (RF) devices, and microneedling. These cutting-edge technologies aim to optimize general skin and mucosal tropism by stimulating fibroblasts, fostering neocollagenesis, and initiating neoelastogenesis through micro-punctures, setting in motion an inflammatory process conducive to the generation of new cells.


Significantly, fractional radiofrequency has exhibited effectiveness in addressing various concerns related to female genitalia, spanning vulvar laxity and functionality, heightened vaginal lubrication, and an increased concentration of type III collagen. Furthermore, the reported advantages are coupled with a minimal incidence of mild adverse events, culminating in a high rate of swift and favorable outcomes.

However, while the evaluation of RF devices for genitourinary conditions often relies on subjective patient-reported outcomes, the scrutiny of pre- and post-treatment histological alterations remains a relatively unexplored territory. Therefore, in this blog, we will compare the Fractional Radiofrequency (FRF) and microneedling in vulvar tissue in female rejuvenation.


Understanding Fractional Radiofrequency (FRF)



Fractional Radiofrequency (FRF) stands out as an advanced cosmetic and dermatological procedure aimed at addressing the diverse skin issues associated with the aging process. This innovative treatment involves the application of a specialized device emitting radiofrequency waves, a form of electromagnetic energy, onto the skin. Notably, FRF employs a distinctive fractional technique, delivering radiofrequency energy in pixelated patterns. This creates microthermal zones within the treated tissue while leaving surrounding areas untouched, fostering a faster and more efficient healing process compared to conventional treatments.

Throughout the FRF procedure, the targeted tissue undergoes heating from the radiofrequency energy, prompting the generation of new collagen and elastin fibers. These proteins are pivotal for providing structural integrity, support, and elasticity to the skin. Consequently, as the skin heals, it undergoes a transformative process, manifesting increased firmness, smoothness, and a rejuvenated, more youthful appearance.


The applications of FRF extend to a spectrum of skin concerns, encompassing wrinkles, fine lines, skin laxity, scars (including acne scars), and textural irregularities. The precision afforded by the fractional approach ensures targeted treatment of specific areas, minimizing downtime and reducing the likelihood of complications. Typically administered in a series of sessions, each session contributes to gradual enhancements in the treated areas, culminating in optimal results. FRF also finds application in vulvar tissue rejuvenation, specifically addressing issues such as sagging and enhancing functionality within the female genital region. This non-invasive approach has gained favor due to its effectiveness in stimulating collagen and elastin production, coupled with the added benefit of minimizing the inconvenience associated with the recovery period.

Past Research

In 2022, a study titled "Comparative Effects of Fractional Radiofrequency and Microneedling on the Menitalia of Postmenopausal Women: Histological and Clinical Changes" was conducted to evaluate the clinical and histological effects of Fractional Radiofrequency (FRF) and microneedling on vulvar tissue among postmenopausal women. A total of thirty participants were randomly assigned to either the FRF (G1) or microneedling (G2) groups. Sub-ablative FRF employed fractionated electrodes with an intensity of 8 mJ, while microneedling utilized a derma roller system. Evaluation encompassed the Vaginal Laxity Questionnaire (VLQ), EuroQol Five-Dimensional (EQ-5D) questionnaire, and the Blatt and Kupperman Menopausal Index (BKMI). Histological insights were obtained through pre- and post-treatment biopsies of the labia majora. Statistical analyses employed paired t-tests for intra-group comparisons and independent t-tests for intergroup assessments.


Results illuminated noteworthy changes in VLQ values post-treatment for both groups (p = 0.01 for G1, p = 0.001 for G2), with no significant intergroup distinctions (p > 0.05). Histological scrutiny unveiled FRF's effectiveness in enhancing fibroblasts, blood vessels, and mitigating fatty degeneration in comparison to the control (p < 0.05). Furthermore, immunohistochemical analysis indicated heightened expression of type III collagen and vimentin in both FRF and microneedling samples (p < 0.05).


In conclusion, this study establishes the efficacy of Fractional Radiofrequency (FRF) and microneedling in addressing flaccidity in the female external genitalia, accompanied by significant histological transformations, particularly in collagen remodeling. The observed positive changes not only highlight the aesthetic benefits but also suggest a potential reversal of age-related structural alterations in vulvar tissue for postmenopausal women.
