Another bigger research using Carpe's main component shown a 61% reduction in sweating after four weeks. Aluminum-based compounds perform better when used on a regular basis over a longer period of time, since the barrier that prevents sweating builds up and is maintained. As a result, dermatologists advocate continuing to use it on a regular basis. However many people will already be using shampoo to keep their hair healthy, so adding more treatments would be unnecessary. There have been some studies showing positive results when using Carpe Diem after hair transplant surgery, but this procedure would require additional visits to a dermatologist to administer the treatment. Using Carpe Diem after hair removal by laser or hot wax removes the need for further treatments as the skin regenerates new cells which die off leaving less chance of irritation due to shaving again. Since aluminum-based compounds remain effective for several months after they are washed out of your body, you can expect to continue to see results from Carpe Diem for quite some time.
