Forgot to test a new serum on a client and learned the hard way
I was working at a tiny spa in Portland a few years ago, and a new client came in for a basic facial. I grabbed a hyaluronic acid serum I had just gotten in stock, slapped it on without patch testing first. About 10 minutes in, her cheeks went bright red and she started itching like crazy. I had to stop everything, give her a cold compress, and calm her down while I figured out what was in that bottle. Has anyone else had a product reaction go sideways on them? How do you handle it without losing the client?
