This Alum Stone stick is a 100% natural deodorant derived from the crystallization of natural mineral salts. These mineral salts are known for regulating perspiration throughout the day, acting as a natural barrier against sweating. Alum, naturally recognized as astringent, helps reduce the size of skin pores while preventing the formation of bacteria responsible for bad odors. Alcohol-free, colorant-free, fragrance-free, aluminum chlorohydrate-free, and preservative-free, this natural product does not block perspiration and allows the skin to breathe while being extremely gentle. Suitable for both men and women, it is used daily as a deodorant for the underarms but also for excessive sweating of the feet and hands, as an aftershave, or for the care of problem skin.
