The Himecoto Shiro Waki Hime (White Armpit Princess) is a specialized Japanese underarm soap designed for armpit care and whitening. This 100g soap features a unique washboard texture containing fruit acids, mannan scrub, and natural ingredients like persimmon tannin and botanical extracts. It effectively removes dead skin cells, cleanses pores, and addresses underarm discoloration while helping control odor. The soap is particularly beneficial for those who frequently use deodorants or experience underarm darkening from shaving. Simply massage the damp soap on underarms for 3-5 seconds and rinse with lukewarm water for best results.
