- Fess up if you're using Retin-A or hydroquinone on your face. "Those ingredients make skin more sensitive, so if an aesthetician doesn't know about them, she risks irritating your skin," says L.A. facialist Sonya Dakar.
- Stop using Retin-A or retinol three days before a peel or laser treatment and a week before facial waxing. "Friends sometimes call me and say, 'Oh, my gosh the wax ripped off my skin!'" says dermatologist Dr. Anne Chapas.
- Ensure a quiet treatment by saying something as simple as, "I prefer to zone out during my treatment, so I won't be chatty today," suggests Dakar. "Say it politely at the beginning, not mid-conversation."
- Bypass the awkward product push at the end by saying you loved the treatment and would like to see how your face reacts to all the products that were just applied. "If budget is a concern, ask for samples," says Dakar.
