Hiya! I’m not sure what a liquid lipstick is, is it like a mix between a lip gloss and lipstick? And I’m assuming that you’re after a glossier/shinier finish rather than a matte finish?
I don’t use lipstick super often but hopefully can help a little.
I would use a lip liner underneath whatever you use, it helps keep the lipstick from feathering and will help keep pigment even after eating and kisses, though you may still need to reapply.
You could try BareMinerals, I’ve haven’t tried, but want to try their Marvellous Moxie range. Picture of swatches below.
Other brands I’ve read good product reviews that don’t test on animals are Tarte Cosmetics, The Body Shop, Too Faced Cosmetics, Urban Decay, Youngblood, NYX Cosmetics, ELF Cosmetics.
NARS Cosmetics don’t test on animals, but some of their products do contain animal products: http://www.narscosmetics.com/USA/customer-care.html#animaltesting
Not sure what side of the fence you’re on with them as some sites consider them cruelty free, others don’t. They have a good selection of different lip products, i.e. cream finish, sheer, matte, semi-matte, lip glosses, gloss pencils, etc. I’ve always heard good reviews about their products. The one I’ve tried, their Velvet Matte Lip Pencil in “Damned” which is a vampy burgundy. The staying power was pretty good and even though it’s a matte lip product, I haven’t found it drying at all, which a lot of matte lip products are. If their matte products aren’t drying, then I can only imagine their other ones aren’t too.
Sorry I couldn’t provide much in terms of pictures. Hope it helps somewhat.
