GBS 3 Pack of Premium Alum blocks 80G - Soothing Aftershave Astringent to Close Pores - Alum Stone Helps Stop Bleeding from Nicks and Cuts

These are exactly as advertised. 3 blocks of alum potasium, perfect for preventing infection after shaving or as an addition to your underarm deodorant to kill the bacteria that contribute to unpleasant body odor. The bars themselves are a little rough: this is a compressed block of salt-like minerals, after all, not a solid crystal. I recently read how various ancient cultures used alum potassium to mitigate body odor. Using the alum bar by itself would have an effect, but it would not be able to prevent the odor completely. Underarm sweat itself stinks, but the bacteria that feed on the sweat make it worse. I've noticed a distinct improvement at the end of the day since I started applying the alum bar to my underarms after my morning shower, but before applying deodorant. The sharp "not terrible, but not good either" component has changed drastically by using this two-pronged attack on stench. As a final note, I would point out that alum potassium is not the same as the aluminum oxide found in antiperspirants. Alum potassium does not block the pores of the sweat glands like aluminum oxide. It merely provides an astringent to sanitize the skin.
