It's in a bottle of a nailpolish so, the too comes off and it has a brush applicator like a nailpolish.
I found it easiest to apply the product with the brush applicator, putting 3-4 dots of the product on the tops of my cheekbones then blending it out with my finger. Although, it doesn't have to be only applied to the face, you can apply it to your browbone or in the inner corner of your eyes.
I really like this highlighter because it is very subtle and glowy. It has a high sheen rather than shimmer or glitter overload. It is suitable for girls with oily skin because it doesn't make you look oily, it gives your a nice sheen and highlight to your face.
I find this product to be very effortless because it looks nice without trying too hard. It only takes two steps to apply it and blend it and it looks really nice and put together. It's an awesome product and it's also awesome for travelling.
I think this would be an awesome product for this time of the month because it's getting very cold where I live (Japan) and since the air is very dry, it gives you a nice healthy looking glow to your face.
Now onto the product pictures and swatches!
