Trouble with this is so many say they're fine with facials but once they've got your money and it gets down to it, they'll either make up an excuse (customer soon, don't want to redo makeup) or they'll dodge it very obviously and/or provide it very unwillingly with an ugly "ewww" grimace face
Personal recommendations are far more reliable than what's written or listed as a 'like' on a profile - this is especially true when it comes to facials
