I ordered the Australis Mineral Liquid Highlighter in Pearl during a 50% off sale. It is the first liquid highlighter in my collection, so I can’t compare it to other liquid highlighters on the market, but here are my thoughts on this product in particular.
Firstly, the illumination is quite subtle. I apply this in one of two ways 1) mixed into my foundation or 2) dabbed on my cheekbones after foundation but prior to setting with a translucent powder. I really like this for everyday wear.

As a point-specific highlighter this is so pretty. It is subtle enough for everyday wear but it gives such a pretty glow. I get quite oily in my t-zone but I haven’t found that this liquid adds to the problem at all when just dabbed lightly onto the skin.

When I use the Mineral Liquid Highlighter mixed into my foundation I just add one pump of the highlighter and mix it into two pumps of my foundation and combine. It is so pretty worn this way! It adds a lovely illumination to the skin which I adore. My skin can be quite dull at the moment and this works well to counteract that. My only criticism would be that at times, I find that adding this to my foundation can make my foundation feel a bit more oily and/or tacky to the touch towards the end of the day (particularly around my T-zone). This may not be an issue for those of you not predisposed to T-zone oil issues. Saying that – I still love the finish and am happy to touch-up with a little bit of powder if/when require.

The highlighter comes with a pump which is great for hygienic application. I just pump a small amount onto the back of my hand.
I have very much enjoyed this Mineral Liquid Highlighter. I had wondered when I purchased this whether or not I would get much use out of it as I tend to preference powder products over creams and liquids, but I have used this SO much and will definitely repurchase it in the future.
In fact, the next time there is a sale, I will happily purchase the other shade in the range called Gold too!
I purchased this highlighter online from the Australis website, and they do ship internationally. If you live in Australia, you can also buy Australis products at Priceline.
Have a fantastic day!
