This study describes a protocol for inducing endogenous reactive oxygen species in mouse skin, which stimulates tissue regeneration and promotes burn healing and hair follicle growth.

This study found that red light exposure significantly enhanced the growth, phytochemical content, and therapeutic potential of Eclipta alba callus cultures compared to other multispectral light exposures.

In this case study, the researchers reported a rare incidence of bilateral hyperpigmented macules on a patient's lower legs, possibly due to cyclophosphamide, suggesting that this chemotherapy drug may directly stimulate hair follicles to cause skin discoloration.

This study suggests that Nox4 is a key factor in the hypoxia-induced enhancement of adipose-derived stem cell functions through reactive oxygen species generation.

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.

This review examines the diagnostic significance of yellow and orange colors in skin lesions and concludes that their role is often underrepresented in the literature.

This study found that Phytochrome A is crucial for regulating central metabolism and the transition to mature seedling proteomes in tomato seedlings grown under far-red light.

This study found that spanlastic gel loaded with thymoquinone and ascorbic acid improved skin deposition and tyrosinase inhibition, suggesting potential as a treatment for hyperpigmentation.

This case study describes a cat with concurrent cutaneous xanthomas, demodicosis, and dermatophytosis, which suggests potential primary hyperlipidaemia as the underlying cause for its symptoms.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This study observed that skin pigmentation significantly attenuates bioluminescent signals in C57Bl/6 mice, complicating quantitative optical imaging and requiring consideration in experimental design.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

In this laboratory study, α-mangostin was found to significantly reduce melanin content and downregulate pigmentation-related genes in cultured skin and B16F10 cells, suggesting potential application as a natural whitening agent in sunscreen development.

This study observed that exposure to different wavelengths of light affects opsin and clock gene responses in skin cells, suggesting potential therapeutic approaches using photobiomodulation for dermatological conditions like psoriasis and wound healing.

This source reviews the health benefits and challenges of using anthocyanins, noting their antioxidant, anti-inflammatory, and other protective effects, while also highlighting stability issues that need addressing for wider food and nutraceutical application.

This study reports on a unique clinical presentation of folliculotropic mycosis fungoides in a 60-year-old man, highlighting complexities in diagnosis due to dense histiocytic infiltration, which led to xanthoma formation before treatment, and obscured lymphomatous features.

Zebrafish skin regeneration relies on cell behaviors and reactive oxygen species, with antioxidants reducing and hydrogen peroxide increasing regeneration.

This report details a case of a 43-year-old woman developing yellowish papular eruptions alongside typical acneiform skin reactions on her cheeks and chest following a switch from cetuximab to panitumumab treatment.

This study engineered a bioluminescent yeast strain responsive to androgenic chemicals, demonstrating rapid and sensitive detection suitable for high-throughput screening and environmental monitoring.

This review discusses the role of melanocytes in skin pigmentation and UV protection, explaining their interactions with keratinocytes and highlighting their involvement in processes like melanin transfer and melanoma development, but reports no new results.

Blocking the JAK/STAT pathway may help reduce skin sensitivity in Xeroderma pigmentosum.

This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.

This article reviews the impact of H2O2-redox homeostasis on hair follicle pigmentation via tyrosinase and associated mechanisms, discussing primarily findings from murine models without providing new clinical results for humans.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

This review discusses the mechanisms associated with protoporphyrin IX in living cells and reports no clinical results; the authors emphasize its potential in cancer diagnosis and the risks of toxicity.

This review highlights the regenerative abilities of *Xenopus laevis*, focusing on how tadpoles regrow complex tail structures and the cellular and molecular mechanisms behind this. It underscores *X. laevis* as a valuable model for understanding regeneration, with insights potentially advancing regenerative medicine.

This study reports that keratinocytes grown under low oxygen conditions (physioxia) demonstrated reduced reactive oxygen species production and increased antioxidant enzyme activity compared to those in higher oxygen conditions, highlighting the role of oxygen in regulating skin antioxidant defenses.
