When you go in for a facial (or sometimes a body treatment), you will likely encounter some form of a product pitch—so be prepared. "If the aesthetician starts mentioning products during your service, just say, 'I'm happy to hear your recommendations, but I'm really here to relax, so please save them for the end,'" suggests Ufland. After your service, if you don't want to purchase anything, ask the aesthetician to write down the products she's recommended (if she hasn't done so already), and let her know that you'll think it over. "Once you say you're not interested right now, they shouldn't say another word," says Ufland. "If they push it, I'd tell the spa manager."
