“…Similar results were reported in a study of 87 patients which showed mean hair reductions of 43% for black hair, 49% for brown hair, and 35% for blonde hair (p < 0.05 all groups) [13]. Conversely, one study demonstrated no significant difference in hair clearance efficacy between fair-and dark-colored hair (p = 0.872) [14]. Sadick et al [18] specifically studied lighter colored hair removal and reported greater efficacy of blonde facial hair removal compared to white facial hair (52% vs. 44%) after four treatments in 36 patients.…”

“…RF appeared to be well tolerated by patients of all Fitzpatrick skin types in the hair removal studies, with no serious adverse events being reported. The most commonly reported adverse events were minor, including transient erythema, edema, hyperpigmentation, and mild treatment-associated pain [10,13,14,17,18]. A total of 7 patients treated with mRF across the three trichiasis studies developed eyelid notching [6,8,9].…”

“…Another study reported an average hair clearance of 75% after 4 treatments in 40 patients at 18-month follow-up [3]. One study noted a positive correlation with treatment number and hair clearance, reporting >50% clearance in nearly half of patients after an average of 5.2 IPL/biRF treatments [3,14]. A similar positive correlation was further described by Schroeter et al [15] who reported a mean hair reduction of 54.7% in blonde-haired patients after an average of 8.5 treatments.…”

Background: Radiofrequency (RF) devices are being increasingly used for cosmetic dermatology applications. Recent studies have reported an apparent dualistic nature of RF devices for hair, causing either removal or growth depending on the modality of RF. Materials and Methods: PubMed/MEDLINE and Web of Science searches were conducted in July 2022 according to PRISMA guidelines for studies discussing RF technology in hair applications (n = 19). Results: The majority of studies describe the utility of RF devices in removal of unwanted hair (n = 15). Bipolar RF has been used in combination with intense pulsed light for effective long-term removal of body and facial hair. The chromophore-independent method of energy delivery in RF makes it a viable add-on therapy for treating lighter colored hair and darker Fitzpatrick skin types. Monopolar RF is used for eyelash removal in patients with trichiasis. In contrast, fractional RF has been used to stimulate hair growth in patients with alopecia areata and androgenetic alopecia. Conclusions: Preliminary evidence supports the use of bipolar and monopolar RF devices for hair removal, while fractional RF appears to be an emerging technology for hair growth. Additional studies are needed to investigate the efficacy, mechanisms, and parameters of radiofrequency devices for various hair applications.

“…An innovative concept was presented by Karsai et al [21]. In a retrospective study, they assessed the short-and longterm effectiveness of an electro-optical synergy device (IPL (l em ¼ 680-980 nm)/bipolar radiofrequency-RF) for hair removal in patients (n ¼ 24) with unwanted facial hair.…”

Intense pulsed light (IPL): A review

et al. 2010

View full text Add to dashboard Cite

Background: Intense pulsed light (IPL) devices use flashlamps and bandpass filters to emit polychromatic incoherent high-intensity pulsed light of determined wavelength spectrum, fluence, and pulse duration. Similar to lasers, the basic principle of IPL devices is a more or less selective thermal damage of the target. The combination of prescribed wavelengths, fluences, pulse durations, and pulse intervals facilitates the treatment of a wide spectrum of skin conditions. Objective: To summarize the physics of IPL, to provide guidance for the practical use of IPL devices, and to discuss the current literature on IPL in the treatment of unwanted hair growth, vascular lesions, pigmented lesions, acne vulgaris, and photodamaged skin and as a light source for PDT and skin rejuvenation. Methods: A systematic search of several electronic databases, including Medline and PubMed and the authors experience on intense pulsed light. Results: Numerous trials show the effectiveness and compatibility of IPL devices. Conclusion: Most comparative trials attest IPLs similar effectiveness to lasers (level of evidence: 2b to 4, depending on the indication). However, large controlled and blinded comparative trials with an extended follow-up period are necessary. Lasers Surg. Med. 42:93-104, 2010.
