I've never tried their tea tree toner or that mask. I typically buy their coffee exfoliating mask with caffeine. It helps fine lines and wrinkles, wakes you up much in the way coffee does and at the end you exfoliate it off.
I made ace my own tea tree toner though by boiling roses, removing them and adding a few drops of tea tree oil ( you can find it almost anywhere). It has truly toned my face and evened out my skin.
i know this isn't what you asked but they are alternatives!
Along with what the fellow member has already stated, I'd recommend also talking to the workers there. They're all highly trained and know everything about most any product and ingredient. Just make sure that you aren't pressured into buying anything you don't need. They'll certainly try to convince you to purchase something that may not be what you want if what you need is not in stock.
You can also ask for samples there as well! Hope you get something good! (Personally, I enjoyed using herbalism as an exfoliator, if you need an exfoliator!)
