Silver ion (nano-silver ion) sanitary napkins have the following characteristics: The product contains nano-silver: Nano-silver uses cutting-edge nanotechnology to nanometerize silver, so that the bactericidal ability of silver in the nanometer state is significantly improved. A leap forward, very small amounts of nanosilver can produce powerful bactericidal effects, killing more than 650 types of bacteria in minutes. It has a strong inhibitory and killing effect on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae, and Chlamydia trachomatis, and will not develop drug resistance. It can promote wound healing, cell growth and repair of damaged cells without any toxic reaction and no irritation reaction to the skin. Moreover, the antibacterial effect of this product becomes stronger when exposed to water, making it more conducive to the treatment of diseases.
