THIS PRODUCT STINKS. I bought it to use while running on my lunch breaks, but only used it once. The scent is powerfully chemical and it irritates my nose badly. I have it in my desk drawer at the office...every time I open the drawer my nose itches again. I am never sensitive to scent, but bought the fragrance free because my office is scent free.
This product is probably very effective; it's approved by the Canadian Dermatology Association, is photo stable and blah and blah and blah. It's only effective if you can USE it though, and I think the smell would drive most people away.
I know I will never use it again... time to take it out of that drawer I guess, and round file it! Yuck!!
