S ummary Aboriginal melanocytes were greater in number, histochemically more active, and contained larger melanosomes than Caucasian melanocytes. Melanin did not appear to be destroyed in keratinocyte lysosomes to the same extent as occurs in the Caucasian. The stratum corneum in the Aborigine had greater electron‐density than in the Caucasian and therefore it was probably a more efficient light filter. Aboriginal skin did not appear to be damaged in any way by years of exposure to the sun.
