Bought this product in the original months ago and found I was very sensitive to it causing a rash on my armpits. Stopped using it and then tried again months later to see if there was any change and still got a rash. Contacted No Pong to ask if this is a common side effect of using & they suggested I try the Bicarb Free version. They were nice enough to send me a free tin to try. I have used it every morning and night since and absolutely love it. I can go about my whole day without any bad smell & have found my sweating has drastically decreased since I started using this product. My armpits feel silky smooth & I can go 8 hours plus with applying this once & my armpits smell amazing all day long. Will 100% recommend to friends and will be purchasing this forever now.
