research miR‐200a‐3p in Human Umbilical Cord Mesenchymal Stem Cell‐Derived Exosomes Attenuates UVB‐Induced Skin Inflammatory Response and Oxidative Stress via Keap1‐Nrf2 Pathway

January 2025 in “Stem Cells International”

This study found that exosomes from human umbilical cord mesenchymal stem cells reduced oxidative stress and inflammation in UVB-induced skin injury in cell and mouse models, suggesting their potential for treating UV-damaged skin by influencing Nrf2 and NF-κB pathways.

Lysine Carboxymethyl Cysteinate Protects the Epidermis from UVB-Induced Barrier Damage Through the Activation of Autophagy

research Lysine Carboxymethyl Cysteinate (LCC) Protects the Epidermis from UVB-Induced Barrier Damage Through the Activation of Autophagy

April 2026 in “Biology”

This study found that lysine carboxymethyl cysteinate helps protect the epidermis from UVB-induced damage by activating autophagy and restoring cornification processes in a skin model.

research In Vivo Role of Vitamin D Receptor Signaling in UVB-Induced DNA Damage and Melanocyte Homeostasis

10 citations , June 2016 in “The journal of investigative dermatology/Journal of investigative dermatology”

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.

research Topical Administration of 15‐Deoxy‐Δ^12,14‐Prostaglandin J₂ Using a Nonionic Cream: Effect on UVB‐Induced Skin Oxidative, Inflammatory, and Histopathological Modifications in Mice

9 citations , January 2021 in “Mediators of Inflammation”

In this study, 15d-PGJ2 administered in a topical cream inhibited oxidative and inflammatory skin changes caused by UVB radiation in hairless mice, suggesting it as a promising treatment approach.

research Brain and muscle Arnt-like protein-1 (BMAL1) controls circadian cell proliferation and susceptibility to UVB-induced DNA damage in the epidermis

221 citations , July 2012 in “Proceedings of the National Academy of Sciences of the United States of America”

This study found that the circadian clock in mouse skin regulates cell proliferation and affects sensitivity to UVB-induced DNA damage, with potential implications for understanding human skin cancer risk.

community Has the failure to take Finasteride while you had the chance encouraged anyone to take preemptive measures against anything else that might happen?

29 upvotes 1 week ago

The conversation discusses regret over delaying finasteride use for hair loss and emphasizes the importance of early preventive measures for health issues, including using sunscreen, taking vitamins, and considering medications like statins. Participants share experiences with finasteride, sunscreen, and other health practices to prevent aging and health problems.

community South Korean Red Light Therapy Study

41 upvotes 6 months ago

Korean scientists developed a red light therapy that reduces a hair loss marker by 92%. Users discussed the benefits and drawbacks of natural sunlight versus red light caps for hair health, with some suggesting supplements for vitamin D.

community The Real Cause Of Androgenetic Alopecia

675 upvotes 1 year ago

Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.

community Could male-pattern baldness have a secondary photobiological function? The Solar Window Hypothesis

11 upvotes 2 weeks ago

Male-pattern baldness might increase UVB exposure on the scalp, potentially affecting vitamin D and skeletal health. The hypothesis is debated, with some seeing it as a minor benefit in specific contexts.
