Here, we aimed to establish a non\u2010invasive method for quantifying the eumelanin and pheomelanin content of the stratum corneum.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Sun\u2010exposed and non\u2010exposed samples from 10 healthy Japanese subjects were compared. We harvested the outermost layer of the stratum corneum by tape\u2010stripping, considering the outer side of the forearm as a sun\u2010exposed area, and medial side of the upper arm as a non\u2010exposed area. Four additional subjects were included in the analysis of change in melanin content over time at the same skin site. The anterior lower leg received a single exposure to two minimal erythema dose sunlight, and the stratum corneum was harvested from the same site over a period of 20 weeks; we subsequently quantified the levels of eumelanin and pheomelanin using high\u2010performance liquid chromatography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We were able to accurately quantify the eumelanin and pheomelanin contents of the stratum corneum, and to observe the evolution of the same skin site over time.
