Due to several health problems I spent most of a summer in and out of hospitals with multiple surgeries. On entering the first time I was given a complimentary sample. Having had time to use the entire 1.5 oz. bottle I found it to be by far the best product of its kind I'd ever used (and I'd tried many of them). It is very effective and without any irritation. I'm on-line now to find a way to get more to continue to use it.
