I love the packaging, very Beauty and the Beast! I think the claim of absolutely invisible is a little pointless, as it also claims to give you a light golden gleam as though flickering light from a candle is softly illuminating your face. That's what I took from the marketing anyway.
I have oily skin, so for me a powder is always necessary, when highlighting I tend to stick to Benefit High Beam or another liquid product as I'm fairly heavy handed with powders so don't want to be too shimmery.
This is a really finely milled product, I had read older reviews of this where people looked like someone has let a primary school class loose with glitter on them, but the glitter (actual gold particles) in this is really fine and not too obvious.
I really love this, and there is a nice version which is half pinky half gold so have a look out for this! It's £22.00 and available from so many outlets online. 10/10
