If you're looking for premium cruelty-free skincare, Chantecaille is good.
There is a bit of a gap at the premium end of the market for cruelty-free things.
Tara Harper is also good at that end of the market- good blend or organic and tech, and cruelty free.
Have just discovered Esse and have tried a few of their things, with good results. Particularly the microderm exfoliator.
Juice Beauty has some good things too.
Love Lula, Content Beauty and Naturissimo are good places to discover cruelty-free brands. Also offer either the ability to buy samples or offer a choice of free samples with purchase.
Love Lula only stocks cruelty free products, but they do include brands who are cruelty free but owned by a parent company that tests.
Naturisimo is all cruelty-free, but I can't find out what their definition of cruelty-free is, so I do a bit of extra digging myself to double check, as I don't buy from companies owned by parent companies who test or companies that sell on mainland China.
Content Beauty are all cruelty-free, in that they don't stock brands that test, or instruct others to test on their behalf. They also clearly Mark any products that are part of a certified cruelty-free scheme.
