This review found that laser-assisted drug delivery in humans was associated with several adverse effects, but no life-threatening events were reported in the studies examined.

This review evaluated existing studies on platelet-rich plasma for facial rejuvenation and found limited clinical evidence supporting its effectiveness, suggesting that more research is needed to establish its utility.

In this study, significant improvements in skin density and thickness, especially around the lower eyelid, were observed across all age groups using plasma fractions from a single blood draw, indicating that the therapy's effectiveness may be age-independent.

This review highlights the potential of regenerative medicine therapies, such as biologics and emerging technologies, to significantly impact aesthetic and reconstructive procedures in plastic surgery and dermatology.

This bibliometric analysis found that research on platelet-rich plasma in dermatology and plastic surgery has increased, with hotspots in facial rejuvenation, scar, and alopecia treatment, particularly from the US and Italy.

This review examines the clinicopathologic features of perifollicular elastolysis and indicates that, while its presentation is consistent, there is a lack of high-certainty evidence for effective treatments.

This meta-analysis reported that platelet-rich plasma significantly improved patient satisfaction and objective efficacy in treating skin aging, while not significantly increasing adverse effects.

This study examines how skin microbiota and the gut-skin axis affect acne development, aiming to reveal mechanisms that could inform future treatment strategies for acne and other inflammatory skin conditions.

This review summarizes the use of autologous platelet concentrates in aesthetic medicine, finding promising results for facial treatments, but highlights the need for more rigorous research due to current study limitations.

This article reviews the controversies that led to the establishment of the ISHRS and its impact on the evolution of hair transplantation, reporting no new clinical results.

In this study, PRP and Yifu combined with ultrapulsed CO2 lattice laser were found to improve sunken acne scars more effectively than laser alone, enhancing patients' quality of life and reducing adverse events, with a higher effective rate compared to the laser-only group.

This article discusses the hair transplantation process and product, but reports no new experimental results; the author is Leonard M. Dzubow.

In this study, researchers demonstrated that treating platelet rich plasma with microsecond pulsed electric fields effectively activates platelets and induces similar or higher growth factor release compared to traditional bovine thrombin, suggesting a potential clinical use that may be more cost-effective and practical.

This study found that low-level pulsed wave red light stimulated collagen and ATP production in human fibroblasts with significantly shorter treatment time than continuous wave light, suggesting enhanced consumer compliance for skin treatments.

This study introduces a new intracavity frequency modulation technique for tunable picosecond optical parametric oscillators, enhancing chemical contrast in coherent Raman imaging by allowing real-time subtraction of background signals.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This study found that the Epilight multiple wavelength pulsed-intense light source was effective for long-lasting hair removal, particularly in individuals with dark hair and light skin.

Low-dose pulsed electric fields in a rat model shifted hair follicles from resting to active growth, with voltage as the most influential factor.

This study suggests that pulsed wave photobiomodulation could be a promising treatment for androgenetic alopecia by enhancing dermal papilla cell function through specific light parameters, particularly frequency.

The authors concluded that controlling voltage, pulse width, and calcium concentration in pulse electric field-activated platelet-rich plasma enhances the release of growth factors and serotonin without causing clot formation, suggesting potential clinical advantages over bovine thrombin-activated PRP.

This study found that pulsed diode laser treatment safely and effectively cleared lesions and reduced the appearance of dark plugs in trichostasis spinulosa for up to 20 weeks in dark-skinned individuals.

This review discusses the development of IPL devices, highlights their established cosmetic uses, such as treating vascular and pigmented lesions, and suggests potential expansion into more effective combination therapies.

In this study, researchers found that progesterone promotes breast tumor growth in mice through its metabolite 5αP, which can be blocked by the 5α-reductase inhibitor finasteride.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This study found that low fluence photoepilation with intense pulsed light targets the pigmented area of hair follicles, causing temporary hair loss by inducing a catagen-like state without severe follicle damage.

Intense pulsed light with radiofrequency showed mixed results in improving quality of life for hidradenitis suppurativa patients, with no clinical improvements.

This study found that the AOPT-MTL mode is an effective and safe treatment option for nasal blackheads in Asians, indicating potential for widespread clinical use.

This study found that both traditional and "in-motion" IPL techniques achieved similar hair removal results, but the "in-motion" method may offer reduced pain during the procedure.

This study found that 808 nm laser photobiomodulation altered mitochondrial respiration and enhanced osteogenic protein expression in human dental pulp stem cells, with the effects being dose-specific and more pronounced at 15 J/cm².

In this study, low-intensity ultrasound was investigated as a noninvasive method for promoting hair regrowth in androgenetic alopecia using C57BL/6 male mice, revealing that specific frequencies and intensities can safely enhance hair regrowth compared to controls by optimizing mechanical effects without causing unsafe cavitation.
