Pearl powder itself is not pure white. Pure white and snow are mostly produced by using bleach or adding talcum powder, which is harmful to health after long-term use. In addition, pearl powder and shell powder will have fluorescence, so this powder is not suitable for use. Pearl is produced by shellfish, and it has an inherent biological smell. Pure natural pearl powder must have a faint smell.
