The question I hear most often from clients is 'how do I get rid of wrinkles?' I tell them to stay out of the sun, use spf, don't smoke, and use products that have beta/hydroxys in them. And, if they're serious about their skincare, microdermabrasion is extremely beneficial.
Leaving gratuities for work well done seems to be the norm, but of course, is optional. Most tips range from 15%-20% of the price of the service provided.
