A perennial favourite, until that is I discovered the marvel that is By Terry's Touche Veloutée. The latter outperforms on several fronts: consistency, shade choice, blendability, ease of application, general appearance on skin and, lastly, sizing.

In short, these products are in different leagues.

this is the perfect under-eye concealer. nothing else compares (other than MAC moisture cover concealer, which is just as perfect).
the colour is realistic and pinky :D and not yellow ( shade No 1 )
I use one or two pumps and put it onto my finger to get the full amount of product out. and then onto my eyes with my finger.
one pump for a natural look without foundation. and two pumps for a fuller look with foundation.
if you just use the brush to apply you won't get the full amount of product as it will absorb into the brush. saying that, no matter how lightly I blend, most of the product absorbs onto my finger rather than my eyes. it's better to pat I think. this also seems very thin and light in coverage, which doesn't help when blending.
apart from this being disgustingly priced, it is a very good product.
it would be my favourite but it's just too expensive. I bought 2 of these and used them up until I found MAC moisture cover (which is much better value for money). but I won't buy anymore touche eclat. this should retail for £15-17 tops.
even if this fits into your budget and your prepared to pay that much for an under-eye concealer, I still don't think it's worth it.

This is a nice product. It looks really natural on my skin but in my opinion the coverage is not that good although its buildable. But there is one thing I absolutely love about the touche eclat: you can put it on even after foundation and powder and it will still look natural and will not crumble or something like that. And until now this is the only product I know which works this way. However one point less because of the coverage.

I like this product, but have one problem usin it. The problem is, when I click it about 3-5 times no product comes out. I have used it about 20 times, really small amounts at a time. In the beginning it was coming out fine, but now .... :S
I have washed and dried it, but nothing helps. It seems like it has run out of product.
I bougth it on ebay for about 10 pounds. Can it be that I got a faulty product? Has anyone else had that kind of experience?

very sheer translucent highligher/corrector. i find it works best round the eyes to reduce "sleepy" eyes or discolored eyes. its sheer tent gives a pearl type sheen which is also great above the eyebrows or along the very high of the cheek bone. also works well to highlight the lip and chin. i frankly love this product. i wish however it would come in a tube as apposed to a brush tip applicator. it makes sanitation an issue for working artist. i only use this on myself.

I recieved a tube of this from a girlfriend who's an absolute YSL lover, so I was prepared to give it a go considering it was free.
Initial reaction was that it was a nice highlighter, but the concealing power was pretty meh. I've been using it on my dark undereye circles and in the dark creases around my nose and it definitely brightens up the area nicely. However in the event of an actual blemish, it's a total let down. I like the idea of concealing and brightening in a single application but I'm not sure they've perfected it just yet. Probably won't buy this again once my pen runs out, but not going to dismiss potentially trying something similar in the future.

Great product! Makes face looking fresh and beautiful! My all time favourite beauty product! Will buy again and again. I have it in shade Nr.2.

I have to admit that i don't know what the fuss is about. It's a concealer pen at the end of the day. Yes, it's in a clever case that makes it easy to carry in your purse. But other than that, i didn't notice anything special about the actual product.

I bought Touche Eclat expecting great things, after hearing so many rave reviews & seeing it achieve cult status amongst fellow makeup enthusiasts.
Unfortunately TE did next to nothing for me. And i mean NOTHING! I was so disappointed with the near to non-existant results this produced once applied to my undereye area. I honestly couldnt tell i had applied anything, which would have been great if my undereyes magically appeared 'better' somehow, but they didnt!
I feel like im missing something here - How do others achieve such amazing results when i cant even tell i applied anything? I did give it another try but was wary to waste any more expensive product for un-noticeable results, so, feeling very disheartened, i swapped TE away and bought a cheaper dupe by L'Oreal to play with, as a last-ditch attempt to experience the supposed face-lifting, eye-brightening youth-enhancing magic that is the highlighter pen... and..
OH. MY. GOODNESS! - L'Oreal Touche Magique is a whole different story! It really lives up to its name - MAGIC! I love love love the (*noticeable*) effect the L'Oreal dupe gives my eyes. Its definitely more opaque than TE and acts as a concealer as well as a highlighter, so you can actually see a difference when using it. It makes my undereyes look so much brighter and younger, and is gorgeous blended down & out to the upper cheekbone, down centre of nose, centre chin and on the cupids bow. This creates the gorgeous face brightening, lifting & ethereal youth-enhancing effect i was expecting from TE - but at a fraction of the cost!
YSL Touche Eclat = FAIL!
L'Oreal TOuche Magique = HG! continued >>

I don't know what it is about touche eclat - once it's on, I don't notice it, I just notice that I look better. Fresher, well-slept, glowing. It just adds...something.

As others below have noted, this is not a concealer- I use it after any necessary foundations or concealing makeup.

I apply touche eclat under my eyes (including the inner corner), on my browbone, on the highest points of my cheekbones, a dab on the bridge of my nose, and a dab on the cupids bow above the lips. Try this!
