The Body's Internal Clock and Skin Diseases

The circadian clock in skin is influenced by various factors including feeding time, which may affect skin functions.

• The internal rhythm of organisms is synchronized with the light-dark cycle, operating on a period of around 24 hours.
• Light signals from the retina play a key role in setting the timing of the circadian clock in the brain's suprachiasmatic nucleus.
• Feeding time has a significant impact on the skin circadian clock and its related functions, an area previously overlooked.
• Disruption of the circadian clock is associated with various skin diseases, including skin cancer, aging, and inflammatory conditions.
• Circadian medicine shows potential for preventing and managing skin diseases by aligning treatment with the body's internal clock.
