The invention provides a pearlescent pigment, a preparation method and a coloring pearlescent pigment for cosmetics prepared from same, which relates to the technical field of cosmetic pigments, the pearlescent pigment comprises synthetic mica and a stannic oxide layer, a silica-doped titanium dioxide layer and a calcium borate layer, which are successively coated on the synthetic mica. Due to theaddition of silicon elements, the photoactivity of titanium dioxide in the silica-doped titanium dioxide layer can be effectively reduced without affecting the color of pearl light. Meanwhile, for the pearlescent pigment provided by the invention, the silicon-doped titanium dioxide layer is coated with the calcium borate layer, which can effectively isolate the effects of free radicals generatedby photocatalytic titanium dioxide on organic matters, thus, the pearlescent pigment and the coloring pearlescent pigment for cosmetics prepared from same provided by the invention have good UV resistance and can effectively alleviate the common phenomenon of color change and color migration in the production and application of the pearlescent pigment.
