If you are hoping that this will give you the similar "glowing" look of highlighter - think again. This might be your lazy option of foundation substitute over winter to go to supermarket, or to "thin out" your hard-formula foundation, but it's nothing more than that. I've tried this in four ways: as a base, mixed with my foundation, mixed with a concealer and as a liquid highlighter.
As a base - it was below average. I honestly didn't see much of dewiness, or glowing feeling from my face. I was hoping that this would cover my dull face in case I forget to do my skincare routine - but I still looked dull without my usual beauty regime. I applied my foundation over the base, but it was gone before lunchtime (in a cool workplace!?). I definitely wouldn't re-use this as a base.
Mixed with my foundation - for summer time, I don't think this was a great idea so will try this in winter time again. I have a combination skin where my skin outside is a bit oily but it's dry inside. Mixed with foundation, my base make up disappeared around lunchtime again.
Mixed with concealer - I've tried mixing this with my fav Nars concealer and only used the area that I wanted to "highlight." I applied with my usual brush and it wasn't so bad.
Liquid highlighter - I had my highest hope as it seemed very pigmented. It was average - it wasn't as pigmented as I hoped it to be on my face. But that being said, if you are looking for very natural highlighter (like barely-there sort of highlighter), then I guess this could work with you. You also don't need much as a liquid highlighter as you can't layer it up.
Wow! Turn on your high beams, ladies, this highlighter is not messing around. Highly pigmented and very glittery, a little goes a VERY long way.
For my first application I used it under a full face of foundation - I used a full drop swept mostly over my cheekbones and a little on my forehead, cupids bow, and nose and then applied my foundation over top - and it was still quite a punchy highlighter look. The rest of my applications were with a much lighter hand - just a tiny, tiny little brush of product on the same places and that worked nicely for a more subtle no-makeup look.
I'm not quite sure what they were thinking with the packaging - the dropper is very unnecessary, as you get more than enough product (and then some) on the outside of the dropper. Trying to apply drops without just getting the product that's clinging to the dropper everywhere seems pretty unlikely, not to mention that I don't think I'd ever want to use that much. There's also a big white sticker on the back of the label with a little 'peel here' arrow, but if you peel it then it never quite sticks back down properly, but if you try to take it off it unwinds to take the whole label off the entire bottle, leaving a tacky mess behind. Small details, but they did slightly cheapen the overall feel of the product.
It definitely requires a bit of care if you're wanting subtlety, but overall I'm very impressed with the product quality, blendability, and staying power. I'll definitely be using this regularly going forward.
