From Clinique :
"Enjoy rapid refreshment and a full 24 hours of soothing moisture with an addictive by-a-waterfall feel. Advanced hydration boosters and a new botanical blend hold skin's moisture in balance through stressful shifts in humidity, indoors and out."
I also buy it because I like to use Moisture Surge as a primer before putting on my make up. I put one generous layer on and then fan it dry before putting on my make up. My blush and bronzer last longer when put on top of Moisture Surge and same goes for my foundation on those odd occassions that I do wear it over my entire face.
