Hydrogen Silicon Esthetic Bath Bath Additive Bagged Bath Additive Active Oxygen Reusable and Economical I received this as a gift, but I haven't used it and it's been stored away. From the manufacturer's website: ■ Esthetic Bath with Silicon and Hydrogen Renewed! "BATHTIME with H2&Si" ■ === Increased Content! === Gentle Esthetic Bath for your skin! Silicon (Silica) has excellent adsorption properties and absorbs chlorine, which is a concern in tap water. Hydrogen acts on harmful active oxygen generated by lifestyle habits. Just by putting it in the hot water, your home bath will quickly transform into an esthetic bath! About Chlorine Chlorine contained in tap water has sterilizing power and is necessary for tap water, but if you continue to use it, your hair will become dry and your skin will become rough. The dryness of your hair after swimming in a pool is due to the effects of chlorine. #Silicon #Hydrogen #BathAdditives #Bathtime #Bathing #Bath #Bathroom #Present
