Potassium alum, a natural mineral salt, is used in the production of SIVENO Roll-On. Potassium alum does not close the pores under the armpits and does not prevent sweating. It only neutralizes the bacteria that cause bad odors. SIVENO Roll-On does not leave a sticky feeling and does not leave stains on fabrics. With its odorless and natural structure, it is suitable for use by all consumers, men and women. It can be recommended to consumers who do sports and spend intense effort. Usage Suggestion: Shake it before use. Apply the product on dry and clean armpits. Put on your outfit after the roll on is completely dry.
