Tell her the truth. There’s no shame in declining to service a customer who is seeking skin improvement you don’t have the ability or legal license to deliver.
In fact, a prospective client will greatly appreciate your honesty over attempting to do something that will likely disappoint.
From time to time, I have to explain to a potential client that the skin result she’s hoping for is beyond my treatment reach, and suggest a different professional, including dermatology.
I’ve never regretted needing to do that nor, to my knowledge, have ever been judged negatively because of it.
