I have a lot of her products and genuinely like them.
That said I think there are a few duds in the range that I wouldn't re-purchase.
The mascaras aren't great - either of them. They go on well but I find they smudge badly.
I'm not keen on the eyebrow pencil - it's too hard and frankly not worth the money.
Magic foundation - too heavy and drying I don't think it's at all flattering.
Wonderglow - it's too glowing for me tbh to use all over the skin.
That said I do like the lipsticks and lip pencils. All the eye quads are lovely colours and blend really well. The bronze and glow compact is great and I love the beach sticks (I used them all summer).
Other favourites include the creme blush (colour of youth) and the colour chameleon eye pencils - a pp didn't rate them but I really like them, easy to apply, you get a bit of play time, then they set. The creme eyeshadows are also very nice and come in some lovely colours.
The powder blush is nice but no better than Nars (actually not quite as good).
I do like the light wonder foundation but I won't pretend it's a holy grail product.
I haven't tried the contour products as I don't "do" countering :-)
Finally the skincare isn't worth the money. It's extremely pricy and I can't see it being good for anyone with combination/oily skin. Don't get me wrong - it's very nice but you can get other products that are just as good for far less money.
