Anhydrol Forte Roll On is a clear, colourless liquid that contains no fragrance. The active ingredient, Aluminium chloride works by blocking the sweat glands. This causes the pressure of fluid within the sweat glands to rise to the point where it shuts off sweat production.
The antiperspirant is applied before going to bed at night and should be washed off in the morning. It should not be re-applied during the day. Over time, sweating will stop during the day and the number of times you apply the antiperspirant at night can be reduced.
