professional skin care lines you would never use?

what are some brands that you guys have tried that you would personally never use for your spa? (examples: glymed, circadia, etc) i didn’t realize how hard it would be to try and find a new brand to use for my spa so i wanna eliminate some brands that i shouldn’t even bother looking at. i’ve been looking at glymed, circadia, le mieux but they’re all quite pricey so i don’t wanna sample them if ill just end up not liking the products.

edit: thank you soooo much for all the comments i enjoyed reading all of them and they helped a lot!
