,
September 2019 in “Experimental Eye Research” This review discusses the role of RDH12 in vision, its structural and functional aspects, and related disease mechanisms, but reports no new clinical results; it aims to support therapy development for inherited retinal dystrophies.
6 citations
,
June 2011 in “British Journal of Dermatology” This study found that individuals with alopecia areata had significantly higher serum levels of retinol-binding protein 4 and increased IgG immunoreactivity against it, suggesting a role in the disease's pathogenesis.

October 2021 in “Journal of Medical Case Reports” This case report describes a possible association between topical 5% minoxidil use and inferior hemiretinal artery occlusion in a 21-year-old Asian Indian male with androgenic alopecia.
July 2026 in “Journal of the American Academy of Dermatology” This study found that patients with alopecia areata have a significantly higher risk of retinal abnormalities, suggesting common immune mechanisms, though the low absolute risk indicates that screening should be led by symptoms rather than done routinely.
January 2025 in “Diagnostics” In this prospective case-control study, researchers found that women with any phenotype of polycystic ovary syndrome exhibited increased retinal nerve fiber layer and choroidal thickness compared to healthy controls, with changes correlated to body mass index.
October 2023 in “Indian journal of ophthalmology. Case reports” This case report described acute vision loss in a patient after forehead injections of triamcinolone acetonide for alopecia areata, attributing retinal artery occlusion to embolization by steroid particles.
May 2020 in “Research Square (Research Square)” This study suggested that non-colony dissociated hiPSCs can be effectively differentiated into functional RPE cells, and hiPSC-RPE cell spheroids showed promise for use in subretinal transplantation in animal models of retinal degeneration.
April 2024 in “Communications biology” The researchers reported that disrupting ATRA signaling by deleting RDHE genes in the hair follicle led to altered hair follicle cycles, composition, and gene expression, indicating RDHEs' role in hair follicle signaling coordination.
44 citations
,
April 2008 in “The Journal of Clinical Endocrinology & Metabolism” This study concluded that although RBP4 and adiponectin levels are associated with visceral fat, they do not independently contribute to the development of PCOS.
16 citations
,
August 1989 in “PubMed” This study concluded that high-dose oral therapy with L-cystine, gelatin, and vitamin A significantly improved hair growth indicators in patients with diffuse hair loss, with no systemic side effects observed.
8 citations
,
November 2007 in “Skin Pharmacology and Physiology” In this study, skin stretching significantly increased the delivery of retinyl ascorbate into the dermis, while sealing hair follicles did not affect absorption through native skin.
4 citations
,
July 2017 in “Archivum Immunologiae et Therapiae Experimentalis” This study observed that patients with recurrent furunculosis had different cytokine profiles compared to healthy subjects and that retinol stimulation altered cytokine secretion in both groups.
2 citations
,
July 1982 in “British Journal of Dermatology” This study reports that retinol acetate inhibited the pro-oxidant effects of benoxaprofen on polymorphonuclear leucocytes in vitro.
1 citations
,
December 2022 in “Journal of applied biological chemistry” This study found that TRP-hair essence significantly protected and improved the quality of human hair, particularly against heat stress, by enhancing cuticle health and maintaining hair color.

May 2013 in “Journal of the Egyptian Women's Dermatologic Society (Print)” Women with idiopathic hirsutism and PCOS have higher RBP4 levels, and PCOS is linked to greater insulin resistance; weight management may help both conditions.
January 2026 in “Dermatologic Therapy” This study found that elevated tissue RBP4 levels correlate with disease severity in alopecia areata and decrease after effective baricitinib treatment, while the rs3758539 polymorphism is linked to disease susceptibility but not to treatment response.
In this case study, the researchers observed that a dermocosmetic formulation with encapsulated retinol led to complete regression of a chronic actinic keratosis lesion on the scalp, suggesting it may be a promising treatment approach.
This study found that the RN-Lip co-delivery system enhanced the stability and skin permeation of retinol and niacinamide, leading to improved anti-aging and skin-brightening effects in vitro.
