research The Circadian Clock in Skin
The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.
research The Melanocyte Photosensory System in Human Skin
Human skin's melanocytes respond to light by changing shape, producing pigments and hormones, which may affect sleep patterns.
research Local Circadian Clock Gates Cell Cycle Progression of Transient Amplifying Cells During Regenerative Hair Cycling
Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.
research Prolactin and the Skin: A Dermatological Perspective on an Ancient Pleiotropic Peptide Hormone
Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.
