FYI : To my surprise, this product is actually a highlighter, not a concealer. I guess all the reviews on the web got me confused.. But you can use it as both I guess, nobody knows anyway :p

PACKAGING

I am in love with the packaging.
It is sleek and elegant, so it's a total plus when you want to touch up your makeup in public ;)
The only downside is you don't know how much product you have left in the tube.

APPLICATOR
The applicator is a brush tip applicator and the way you get the products out is by clicking the bottom part of the pen. I think it is very hygienic to have this kind of applicator, oh and the bristles are so soft, so no need to worry when you want to apply it on delicate area like your under eye.

SHADE AND PRICE

under the light, can you see the glowing effect on the skin?

I got this in the shade 02-Luminous Ivory and I think it's a good match for my skin color (You can see from the swatches above). The price of this product in the YSL website is $41, but I don't have any idea about the pricing here in Indonesia, but I will assume it is around that, which is quite pricey for a highlighter/concealer in my opinion.
APPLICATION, FORMULA, BEFORE AFTER

As a highlighter, for me, I apply this product on parts that need to catch more light, like inner corner of my eyes, bridge of my nose, cheekbones and my cupid's bow, but.. I also use it as a concealer, which I will show you in the before after photo.
Application is very easy, just apply it directly to your face, and blend it with your fingers.

Formula is very light and blendable. Not streaky, not sitting on top on your face like what few concealer does, it just blends very nicely and looks very natural. Good stuff.

Here is the before after effect of the product.


I don't know if you can see the difference in the pictures, but, for me, this product that gives a very subtle difference. As a concealer, it is very sheer, but it is actually enough to conceal my dark circle. As highlighter though, I like my highlighter to be BAMM it's there, so I don't really like the effect that this product resulted because I think the difference is hardly noticable.

OVERALL
I think this product is very well formulated and packaged, but knowing that it only gives a very subtle difference to my makeup and nobody can't really see it anyways, I think the product is quite overpriced. For me personally I won't repurchase the product, but if someone wants to give me this, I will still be super happy because the packaging is just too pretty, luxurious and it works just fine! <3

Hope it helps you all, lavs!
