Secret Invisible Solid goes on dry and stays dry with a smooth, even application. This unique formula features proprietary sweat-activated technology, which captures odor and releases fragrance. The sweat-activated technology uses odor-neutralizing molecules to trap odor, lock it away, and then replace it with fresh scent to keep you smelling clean and fresh all day long. Secret Invisible Solid helps stop underarm odor before it starts with 48-hour odor control and wetness protection. Discover unstoppable freshness with Secret Invisible Solid.
