On the left is the Shu Uemura Depsea Water and to the right, the little pink atomizer is the Travalo. You can get the Shu Uemura water from Sasa.com, for approximately $22. The Travalo, I got from CVS for $10.
So what is "Depsea Water"? I'm pretty sure they mean "deep sea water". It comes in a variety of fragrances (rosemary, mint, etc) but I got the non-fragranced for fear of a bad reaction. I mean, this is sprayed directly on my face, after all. I got it for the Summer because you can easily spritz some of the solution on yourself to get instant hydration and refreshment, hence the travel-sized Travalo. You also have the option of spritzing some on your face prior to applying foundation, just to give yourself the extra skin-quenching umph.
Have to tell you, I was a little disappointed. I didn't experience any hydration, no matter how many spritzes I used. It was pretty much water on my face, nothing special. Definitely refreshing though; I was thinking about putting it on my fridge and spraying it here and there on those hot days. Haven't done it yet because Fall's already rolling in!
I think the price is pretty high for what it is... maybe it's more worth it if I'd purchased a fragranced one, but for now, I could've put some tap water in my travalo and achieved the same effect that this $22+shipping thing does. For instance, rosemary is supposedly good for the hair, so if I spritzed some Rosemary-Depsea Water onto my hair (which is also sold on Sasa.com), maybe it'll be worth it. I do however have the stinking feeling that I could just put some rosemary in some tap water in a spray bottle and get the same thing....
Love the Travalo though; easy fill, fine mist, and very convenient. Might go back for seconds! They also have a variety of colors.
