May 2026 in “Frontiers in Medicine” This study concluded that combining the Shumin treatment instrument with oral doxycycline provides better clinical outcomes for rosacea than combining red light therapy with doxycycline, while both regimens improved quality-of-life scores and reduced Demodex counts.
April 2026 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.
January 2026 in “Journal of Dermatology Research and Therapy” This case series found that topical janus kinase inhibitors, along with oral fexofenadine and vitamin D supplementation, significantly reduced disease severity in Black pediatric patients with alopecia areata, demonstrating substantial hair regrowth and minimal adverse side effects.
November 2025 in “Journal of Investigative Dermatology” This case series observed that five Black pediatric patients with moderate to severe alopecia areata showed significant hair regrowth and minimal disease activity after treatment with topical JAK inhibitors, vitamin D supplementation, and antihistamines, with additional therapies in some cases.
January 2025 in “Journal of Cutaneous and Aesthetic Surgery” This review indicates that various laser therapies, alone or combined with other treatments, show potential in improving hair density and treating androgenetic alopecia, but outcomes can vary, underscoring the importance of personalized treatment.

November 2025 in “Revista Multidisciplinar do Nordeste Mineiro” This study's review of existing literature suggests potential benefits of red LED photobiomodulation for treating telogen effluvium, but highlights a lack of standardized parameters and calls for further controlled trials.
June 2025 in “Journal of Education Health and Sport” This review highlights that while finasteride and minoxidil effectively treat androgenetic alopecia, emerging options like dutasteride, mesotherapy, androgen blockers, and red LED therapy show promising results, especially when used in combination, though further research is needed for standardization and safety confirmation.
December 2024 in “Dermatological Reviews” This review highlights significant advances in understanding and treating Alopecia Areata, emphasizing the effectiveness of JAK inhibitors like baricitinib, ritlecitinib, and deuruxolitinib for systemic treatment, while also noting ongoing research into new therapeutic approaches such as stem cell therapy and energy-assisted drug delivery.
January 2018 in “Archives of dermatology and skin care” This systematic review found widespread support in existing literature for the effectiveness of low level laser therapy in promoting hair growth, but emphasized the need for larger case-controlled studies to confirm these results.
June 2025 in “Albus Scientia” This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.
April 2016 in “Journal of The American Academy of Dermatology” A woman's skin symptoms led to a diagnosis of systemic AL amyloidosis, but she died from sepsis shortly after.
October 2022 in “Journal of ophthalmology” This review discusses the implementation and mechanisms of photobiomodulation therapy in various medical fields, including ophthalmology, and reports no new clinical results.
