Controlled light treatment in mouse skin speeds up healing and hair growth.
research Sun-protection behaviors of melanoma survivors
Melanoma survivors are more likely to use sunscreen and seek shade than others, but less than half often use sunscreen and avoid the sun, and some still use tanning beds.
research Characteristic intraepidermal nerve fibre endings of the intervibrissal fur in the mystacial pad of the rat: morphological details revealed by intravital methylene blue staining and the zinc iodide-osmium tetroxide technique
Methylene blue staining effectively highlights detailed nerve structures in rat fur.

Less differentiated melanoma cells are more vulnerable to a type of cell death, which could improve cancer treatments.
research Human Hair Follicle and Epidermal Melanocytes Exhibit Striking Differences in Their Aging Profile which Involves Catalase
Hair follicle cells age faster and lose pigment due to less catalase, causing hair to turn gray.
research Desmoplastic melanoma presenting as an alopecic patch in a young patient
A man had a rare skin cancer that looked like a bald spot.
