The invention relates to an experimental method for analyzing the
toxicity and the effect of a
skin whitening agent through a
primary culture human being skin melanocyte. The method comprises the following steps: 1, culturing and identifying the primary
human being skin melanocyte; 2, carrying out the analysis of the
toxicity of
skin whitening substances through the primary
human being skin
melanocyte; and 3, carrying out the analysis of the effect of the
skin whitening substances through the primary human being skin melanocyte, namely carrying out the analysis on two aspects of the
melanin content and the
tyrosinase activity. The method has the following advantages that: the human being melanocyte cultured
in vitro has a high division and multiplication capacity, a high
standardization degree, little difference between batches, and the same function of producing
melanin granules with the melanocyte
in vivo; the result obtained through the healthy human being melanocyte is more reliable than the result obtained through animal or human-derived
melanoma cells; and the toxic action and the whitening effect of the substances to be tested are evaluated from the two aspects of characterization and quantification. The method can replace the
living body animal and human being skin, and can be directly applied to
toxicity and effect experiments of the whitening substances in products such as chemicals,
cosmetics, medicaments, and the like.
