This study found that UVA blocker-containing sunscreens instantly reduced follicular fluorescence due to porphyrins in facial skin, with the effect lasting for a few hours, influenced by sunscreen amount and formulation.

In this study, the researchers found that the picosecond pulsed alexandrite laser (PSAL) may be as effective and safe as the Q-switched alexandrite laser (QSAL) for treating freckles in Chinese patients.

This review outlines current and potential cosmetic and dermatological applications of low-level light therapy, like photorejuvenation and hair regrowth, and reports no new clinical findings.

This chapter highlights various commercial and open-source light sheet microscopy systems, detailing their rapid evolution and integration of multimodal technologies, with a focus on the ZEISS Lightsheet Z.1 system's advanced design for direct imaging and specialized sample mounting.

This review discusses the applications and advantages of LED-based photobiomodulation therapy for dermatological and cosmetic purposes but highlights existing challenges and health concerns while exploring future perspectives.

Various treatments can improve post-acne scars, but results vary.

This study concluded that the 800-nm diode laser is effective in enhancing skin structure and collagen expression via the TGF-β/Smad pathway, suggesting potential for non-ablative rejuvenation.

This review covers the diverse cutaneous and systemic presentations of sarcoidosis in patients with skin of color, emphasizing the importance of early recognition to improve outcomes despite a generally poorer prognosis compared to Caucasians.

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.

This study found that intense pulsed light treatment achieved a mean of 85% hair reduction in two patients with faun tail, although local anesthesia may be needed due to severe pain associated with neurological abnormalities.

This review discusses advancements in laser hair removal technologies and the potential role of radiofrequency for certain hair types, but it reports no new clinical results.

This review discusses the role of hair follicles in wound healing and scar remodeling, emphasizing that hair follicle transplantation may aid in faster wound closure and scar reduction by enhancing the cellular and molecular mechanisms involved in scarring.

Lasers are effective for hair removal, especially for conditions like excessive hair growth.

This review suggests that radiofrequency devices may be effective for both hair removal and growth, depending on the RF modality, but further research is needed to clarify their efficacy and mechanisms.

This review reports that biomaterial-based drug delivery systems show promise in overcoming the limitations of traditional therapies for pathological scars by integrating sustained drug release with minimally invasive transdermal technologies, potentially enhancing treatment efficacy for these challenging skin lesions.

This source reports that for treating keloids and hypertrophic scars, combination pharmacotherapy targeting multiple sites is generally more effective than using a single drug, though outcomes of individual therapies vary and the development of satisfying treatments is ongoing.

This narrative review discusses the promising role of photobiomodulation in dermatology, emphasizing its non-invasive nature and potential benefits, but acknowledges the need for further research to establish standard protocols.

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 a CLSM-based approach could semi-quantitatively assess the transdermal penetration behavior of fluorescent dyes with different lipophilicities, offering a tool for early-stage screening of compound penetration.

This article reviews the use of laser and light-based devices for hair removal, highlighting their effectiveness in significantly reducing hair growth in individuals with fair skin and dark hair, and suggests that photoepilation offers advantages over traditional hair removal methods.

This review investigates laser-induced Koebner-related reactions and highlights how different laser types, targets, and session frequencies affect the development of these skin responses, particularly in individuals with darker skin phototypes.

In this study, researchers reviewed data on isotretinoin and concluded that delaying certain skin procedures like laser hair removal and chemical peels after isotretinoin treatment may not be necessary, though caution is advised for fully ablative treatments, and lower isotretinoin doses are recommended.

This study found that combined intense pulsed light and low-level light therapy significantly improved ocular surface outcomes and quality of life for patients with meibomian gland dysfunction and dry eye disease.

This review discusses recent advancements in light-based bioelectronic devices for health monitoring and therapy, summarizing key technologies and highlighting challenges and opportunities without reporting new clinical results.

This review found that many low-level light therapy studies report beneficial effects but often fail to provide adequate measurement details, affecting the reliability and repeatability of the research.

This study reviews the complex pathophysiological mechanisms of long COVID and suggests a "treatable trait" approach for targeted interventions based on these mechanisms.

This study introduced laser particles as a new imaging probe capable of real-time tracking of thousands of individual cells in 3D tumor models, suggesting potential for advanced single-cell analyses.
