Useful information, practical tools and informative guides, carefully selected to meet your needs. This advanced method has been clinically validated in over 20 published studies. The use of ultrasound to enhance cutaneous drug penetration (sonophoresis) presents key differences between high and low frequencies, with important implications for local, regional and systemic drug delivery. Study evaluates the efficacy of plasma fractionated radiofrequency and ultrasound with platelet-rich plasma for the treatment of striae distensae. Promising results. Study on the use of ablative fractional radiofrequency and low-frequency ultrasound to improve triamcinolone delivery in the treatment of hypertrophic scars, showing significant resolutions and improvements with fewer side effects. Ultrasound-enhanced transdermal drug delivery overcomes the limitations of the skin barrier, offering a wide range of applications. Transdermal drug delivery has been studied for 40 years. Only around 40 products are on the market, due to the size of the patches and the skin barrier. Physical and chemical approaches to improving transdermal flow are being explored, including electricity, ultrasound, microneedles and adhesives. This review explores strategies for passive delivery of peptide and protein drugs through non-invasive techniques, such as chemical activators, nano-transporters and other approaches, to overcome the stratum corneum skin barrier. Transdermal drug delivery is a potential non-invasive route, but the skin barrier limits its use. This review explores techniques to enhance drug penetration through the skin, such as physical (ultrasound, iontophoresis) and chemical (sulphoxides, terpenes) enhancers, as well as particle systems (liposomes, niosomes). An innovative method combining radiofrequency, ultrasound and transepidermal drug delivery has been tested to treat atrophic and hypertrophic scars. The 14-patient study showed significant scar improvement with similar, predictable results. Ultrasound can cross the skin barrier to deliver drugs, offering promising applications but requiring development for commercial success. The combined use of ablative fractional radiofrequency and acoustic pressure ultrasound with 0.05% retinoic acid cream is safe and effective for the treatment of alba stretch marks. This study examines the efficacy of a combination of photodynamic therapy and drug applications to treat multiple actinic keratoses. Controlled study evaluating transepidermal penetration of a cosmeceutical with radiofrequency and ultrasound: the Legato device facilitated prolonged and effective dermal penetration. The combination of microneedling and ultrasound for transdermal drug delivery shows great potential in increasing skin permeability and improving drug diffusion through the skin. This review explores the mechanisms and benefits of this promising technique. This study aims to determine the efficacy and safety of a new facial rejuvenation procedure combining a fractionated carbon dioxide (CO2) laser, an ultrasound emitter and an intraoperatively applied cosmeceutical preparation, demonstrating significant improvement and patient satisfaction. Low-frequency ultrasound (US) applied to the skin (sonophoresis) has been studied to improve transdermal transport of various drugs. We studied the transdermal penetration of histamine with sonophoresis in a randomized trial. The results showed an increase in histamine skin penetration with the use of sonophoresis, offering potential implications for allergy testing. The combination of fractional ablation and ultrasound assistance could improve the penetration of topical drugs for various skin indications. Transepidermal drug delivery using fractional ablative resurfacing methods combined with acoustic pressure ultrasound represents a promising new option for the treatment of patchy alopecia, with satisfactory clinical results and a low incidence of side effects. This review examines recent advances in sonophoresis for drug delivery, addressing the challenges of safety, device miniaturization and cost. Although sonophoresis shows potential for increasing skin permeability to various drugs, its therapeutic efficacy still requires further evaluation and combination with other enhancement techniques. Sonophoresis improves transdermal drug delivery by temporarily increasing skin permeability. Low-frequency sonophoresis (LFS) facilitates transdermal delivery of hydrophilic drugs and macromolecules, expanding non-invasive therapeutic options. This research evaluates the increased efficacy of the combined use of the fractional CO2 ablative laser and the transdermal acoustic pressure wave device to enhance deep aminolevulinic acid (ALA) penetration, demonstrated in vivo by fluorescence microscopy. Study of a new method of treating acne scars using radiofrequency and ultrasound technology, showing significant short- and long-term improvement, with high safety and patient satisfaction. This abstract discusses recent advances in transdermal drug delivery, including iontophoresis, sonophoresis, electroporation and other techniques. Advantages, challenges and combined approaches are discussed for more effective use of these methods. Our experts will provide personalized advice by assessing your scalp, your haircare routine, and your lifestyle. — Resources
