Philosophy and facials

[livesamantha]

Today I was shopping at the mall and stopped by the Philosophy counter at Macy's. A really nice saleswoman came to help and I told her I want to try some products since I've heard such good stuff. Then I said I wanted to look up reviews on makeupalley and come back, so she said on the 17th they are doing free facials and if I wanted to set a time I could come back then and do that plus figure out what products I want to try. I'm wanting to know if anyone has an idea of what kind of facial treatment this will be? I know it's free but am I supposed to tip? Or just purchase product, and if so is there a minimum $ amount? It looks like they set the times for one person every half hour. I've had facials at salons before so I'm not expecting the real deal, but if someone has any inside info I would appreciate it!

Oh and I'm thinking of getting the sea hydrating mist because it smells amazing and I have dry skin. Anyone have this?
