Space NK is the kind of place I aspire to be able to pop in and just buy some lipstick spontaneously.
They are a luxury beauty retailer in the UK, and they sell quite a few niche, smaller brands as well as bigger ones.
Essentially, as with any retailer, avoiding bigger brands is the best way to avoid brands with bad company ethos. I wouldn’t purchase from Nars, Laura Mercier, by Terry, Kevyn Aucoin, or Nails INC.
Here’s a (non-conclusive) list of their cruelty free brands:
Aurelia Probiotic Skincare
Becca (owned by Estee Lauder)
Bjork and Berries
Dr Dennis Gross
Malin & Goetz
Sister and Co
