This case report diagnosed variegate porphyria in a 33-year-old woman based on significant laboratory abnormalities, but with clinical features resembling porphyria cutanea tarda.

This study suggests that the Grasp protein may play a role in regulating skin homeostasis following UVB exposure by influencing p53-mediated apoptotic responses in mice.

This article reviews the versatile applications of red and infrared light therapy, reporting that these treatments can enhance skin health by modulating cellular processes such as RNA and protein synthesis, oxygen consumption, and reducing oxidative stress and inflammation.

Vitamin D affects skin and hair by influencing cell behavior and melanin production.

This review article found no concrete evidence supporting the existence of "silicone implant illness" as a new syndrome, despite the association of various symptoms with breast implants which are considered safe according to current evidence.

This review discusses treatments for demodicosis in adults and children and provides no new clinical results; the authors emphasize the need for careful diagnosis and therapy selection.

This study assessed the antioxidant properties and contents of carotenoids and chlorophylls in 10 plant oils, finding fenugreek seed oil to be highest in carotenoids and pomegranate oil most active against free radicals, highlighting their potential as natural materials with antioxidant benefits.

This study highlights the importance of dermoscopic examinations in accurately diagnosing skin cancer, which can be mistaken for benign seborrheic keratosis, emphasizing the need for trained interpretation to avoid missing malignant lesions.

This study will explore skin and hair characteristics of pregnant women and their newborns, examining the relationships between these factors and the newborns' skin maturation over time.

This study observed that applying polyamines to the skin of hairless mice stimulates thymidine incorporation, suggesting polyamines may play a role in DNA synthesis control in the epidermis.

This study concluded that topical psoralen and ultraviolet A photochemotherapy is an effective and safe treatment for alopecia areata, as it produced a good response in 43.8% of patients.

This study found that a combination of photoprotector and nighttime formulations with essential oils improved skin barrier function and structural characteristics in young men's oily, acne-prone, and photoaged skin.

This review discusses the protective and stress-buffering roles of melatonin in skin functions and structures but does not present new clinical findings.

This study found that among men over 70, certain genetic variants associated with skin pigmentation affect serum PSA levels, with implications for how sun sensitivity and exposure may influence prostate cancer risk.

This study demonstrated that visible light lightens blond hair more effectively than ultraviolet light, attacking melanin granules directly, whereas ultraviolet light primarily damages other hair tissues following washing.

This review examined clinical studies on topical melatonin for skin protection and found strong evidence that it effectively prevents skin damage from radiation, but noted limited clear evidence for its anti-aging and hair growth benefits due to study design limitations and combined treatments.

This article discusses how vitamin D supplementation impacts human aesthetics and health, with effects varying positively or negatively based on different dermatological conditions.

In this study, researchers found that the vitamin D receptor plays a crucial role in promoting differentiation and protecting against UVB-induced DNA damage in murine melanocytes, suggesting potential implications for melanoma progression.

The study found that in mice, conditional knockout of p53 in epidermal keratinocytes reduced food intake following UVB exposure and resulted in anxiety-related behaviors, suggesting that p53 plays a role in appetite stimulation and anxiety via UVB-induced β-endorphin production.

Increased pigmentation may protect skin from UVB, new targets for skin disease treatments were identified, sunscreen ingredients don't affect hormones, TNF-α inhibitors may help diabetic wounds, and certain treatments could prevent chemotherapy-induced hair loss.

This study suggests that establishing international consensus guidelines for including concealed or sensitive sites in routine forensic examinations is crucial to clarify clinician responsibilities, guide patient expectations, and reduce potential medicolegal issues.

This study enrolled nine patients to investigate the effects of oral psoralen and ultraviolet A therapy plus oral prednisolone for treating alopecia areata.

This study found that Cream 1 effectively prevented UV radiation-induced nerve ending damage in human skin samples, unlike placebo and SPF15 creams.

Sunlight-powered therapy can effectively and painlessly heal diabetic wounds.

This study developed a chalcone-based molecule that significantly increased tyrosinase inhibition and solubility, showing potential as a safe and effective skin depigmenting and antiaging agent, with supportive epigenetic and antioxidant properties observed in vitro.

This study found that while participants in Jeddah, Saudi Arabia, had good knowledge about Vitamin D and recognized sunlight as a key source, there was inconsistency in their attitudes towards maintaining adequate Vitamin D levels.

This article does not contain an abstract and presents no new clinical findings, instead discussing prior cases and literature on infant alopecia universalis and the potential role of topical PUVA therapy.

This review discusses the dual effects of sporting activities on skin health, highlighting potential risks like skin diseases and benefits such as improved outcomes in chronic skin conditions, but reports no new clinical results.

This study found that Gynostemma pentaphyllum hydrodistillate and Damulin B exert significant anti-photoaging effects in UVB-irradiated models by reducing oxidative stress, improving ECM integrity, and enhancing skin hydration and elasticity.
