I have been using Secret Clinical Strength for several months. It is a new type of deodorant designed for use at night (it can also be used during the day just like a normal deodorant). The idea behind this is that at night, the deodorant has time to absorb into your sweat glands and skin, providing you with all day protection. Your body temperature is lower at night, so the product is not immediatly used up or sweated out/off.
The main ingredient is Aluminum zircoium trichlorohydrex GLY (20%) which is the anti-perspirant.
I have had great success with this product - I tend to sweat a little more than I would like, and using this has kept me drier and fresher all day. On warm days or days I know I will be running around a lot, I still use a "normal" antiperspirant in the mornings for an extra layer of protection.
The scent is light and clean, and still is there even in the morning! It has really helped me to feel more confident in clothing that can show "sweat stains", as I stay drier through out the day. I have been very pleased with this product!
