No smell...
First, I have to say that the product I purchased at a spa before in the old style bottle was Fragrant Mist which is what I thought I was purchasing on your website. I did not know that there was a difference, and I don't think I saw 2 different types of mists when I purchased this one.
Second, I'm not sure what the Hydrating Mist is for because moments after I have sprayed it, I smell nothing. And my hubs doesn't smell it at all. He loves the original Fragrant Mist which I'm sadly almost out of. I wouldn't think it would be as potent, but for the money, I definitely would like to have a hint of fragrance surrounding me.
