This is the mode of action of Eucerin 72 h Anti-Transpirant Intensive Pump Spray clinically proven to reduce sweat by 91% on persons with excessive perspiration.
Stronger anti-transpirants, containing Aluminium Chloride, are usually applied at night before you go to bed. This is because you stop sweating in your sleep, so the solution can seep into your sweat glands and block them. This reduces how much you sweat the next day. It can take a few days for Aluminium Chloride to build up its effect. It’s therefore recommended that you start with more frequent applications, and then reduce over time until you have your sweating under control.
