It's not particularly new, but I absolutely adore Lemon Aid. By benefit. It's to cover up eyes, it works perfectly. and I also use it as concealor, as I have basically milk white skin. Best concealor I've ever had!!!
I would second Benefit, it's quite a special type of make-up - expensive but worth it. Good tricks of having a flawless finish and some really good pamperign stuff!
It really depends on how much you want to spend on her, but I would definitely recommend getting her some professional make-up brushes. They aren't cheap, but really are worth it.
My mum bought my set for Christmas and they were the best prezzie I had.
I will try and find out where she got them if you think it's a good idea, but they were about �35 for around 15 brushes.
