To obtain an inorganic blue fluorescent material that is composed of elements for which there are no suspected harmful effects on humans, and that has excellent texture when applied to skin. A fluorescent material for a cosmetic being a composite oxide containing from 0.0005 to 0.05 (in terms of a mole ratio relative to 1 mol of phosphorous in a molecule) of Ce in a compound represented by general formula Ca.sub.aP.sub.bO.sub.c (3.2≤a≤5.0, b=2, c=a+5) and having an average particle diameter of from 1 to 10 μm.

The present invention provides a cosmetic product capable of making the skin look youthful and producing a natural three-dimensional appearance. The present invention relates to a cosmetic product including two or more phosphors each containing an inorganic compound, wherein the cosmetic product, upon excitation by excitation light having a wavelength of 365 nm, emits an emission spectrum having a fluorescence emission peak in each of the range of 400 to 530 nm and the range of 620 to 720 nm and having an I.sub.2/I.sub.1 of 1 to 30, where I.sub.1 is a maximum emission intensity in the range of 530 to 620 nm and I.sub.2 is a maximum peak intensity in the range of 620 to 720 nm.

The present invention discloses one or more compounds that oscillate between a first state and a second state due to absorption of high energy, with the oscillations facilitating prevention of solarization of a glass system for reuse while generating scintillations for determining existence of high radiation energy. The generation of scintillations have a duration that is commensurate with a duration of the irradiation of the glass system, and cease when irradiation is ceased without affecting the glass system.
