This study found that C. japonicum flower extract significantly increased melanin content and cellular activity in human melanocytes and may improve follicular depigmentation and vitiligo through cAMP signaling.

This review discusses the various uses of retinoids, derived from vitamin A, in cosmetic and dermatological treatments for conditions like acne, psoriasis, and skin aging. The authors emphasize retinoids' limited use due to their susceptibility to degradation and safety concerns, particularly with retinoic acid.

This literature review highlights the effectiveness of topical vitamin D (e.g., calcipotriol, calcitriol) in treating vitiligo, emphasizing its role in melanogenesis and as an immunomodulator, either alone or combined with topical corticosteroids, offering minimal side effects.

This study observed that the Aptamin C® and vitamin C complex had effective ROS-scavenging and anti-inflammatory effects on human skin in both in vitro and clinical tests.

Dithranol reduces inflammation in alopecia areata by lowering certain immune responses.

This study found that a polyherbal sunscreen cream, F4, containing Camellia sinensis, Vitis vinifera, and Silybum marianum extracts demonstrated strong antioxidant and photoprotective properties, similar to synthetic sunscreens.

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.

This study found that low-dose topical alpha-terthienyl combined with UVA radiation can induce cutaneous photosensitization in guinea pigs, suggesting a possible photochemotherapy approach for skin diseases like psoriasis.

This study found that the retinoid LGD1069 suppressed mammary tumorigenesis in a mouse model without observable toxicity, while TTNPB showed modest effects but was associated with significant toxicity.

In this study, carotene injected into the skin was converted into vitamin A by sebaceous gland cells, where it was not normally detectable.

In this study, the multifunctional Hair BB Cream containing botanical extracts and other ingredients improved hair combability, increased shine and strength, and provided UV protection, highlighting its potential as an effective hair care product.

This study reported that applying a cream with 5% vitamin C reduced dermatoporosis-related purpura, suggesting the condition may be linked to vitamin C deficiency.

This study found that a single high dose of oral vitamin D reduced UV-induced skin erythema and inflammation in humans by enhancing autophagy, suggesting new clinical avenues for skin repair.

This article reviews the current status of oral retinoids in dermatology and reports no new clinical findings.

This research outlines how retinoids, compounds based on vitamin A, activate nuclear receptors to influence cellular processes such as differentiation and carcinogenesis, with benefits like anti-inflammatory properties but requiring careful management of dose-dependent side effects.

This article reviews the use of retinoids, such as tretinoin, isotretinoin, and etretinate, in dermatological treatments, highlighting their efficacy and side effects, but presents no new clinical findings.

This study found that Carthamus tinctorius extract significantly increased the length of cultured hair follicles and may be a promising topical agent for hair growth promotion with high skin permeation.

In this study, the vitamin D analogues 1 alpha,25-dihydroxy-vitamin D3 and calcipotriol were found to thin the living cell layer and affect differentiation marker expression in organotypic cultures of human outer root sheath cells.

In this study, 13-cis-5S*,8S*-epidioxy-5,8-dihydroretinoic acid was found to be significantly more cytotoxic to cancer cell lines than other retinoic acid analogs evaluated.

This study found that both topical calcipotriol and narrow band ultraviolet B phototherapy improved hair regrowth and vitamin D3 levels in alopecia areata patients.

In this study, researchers found that both thermolabile and thermostable forms of phenol sulfotransferase contribute to the sulfation of minoxidil, emphasizing the need to consider both enzymes in assessing sulfation in human tissues.

This study found that olive and olive oil may significantly reduce cardiovascular disease risk, cholesterol, and blood pressure, while offering antioxidant protection through bioactive metabolites like oleuropein.

This article discusses tretinoin, noting its approved use for acne and photoaging and its broader application in treating various dermatological conditions, but reports no new clinical findings.

In this study, women treated for androgen-dependent alopecia with CPA EE2 therapy experienced significant decreases in serum vitamin B12, hemoglobin, and hematocrit levels after six months.

This paper reviews various vitamin deficiencies, including vitamin D, and highlights their potential health impacts. It does not report new research findings but discusses current recommendations and risks associated with these deficiencies.

This study suggests that dietary vitamin A may influence alopecia development and progression, but the mechanisms remain unclear, highlighting the interplay between genetics and nutrition in these hair loss conditions.

The researchers reported that dPGS-PCL as a carrier improved the penetration of tofacitinib in an ex-vivo human skin model compared to free tofacitinib, but did not show significant differences in inhibiting IL-6 and IL-8 during short incubation.
