Even if you have never tried this delectable, dewy, eye-lift-in-a-gold-pen, you will have most definitely heard of it - unless you have been living under a rock for years, in that case let me inform you of this magnificent treat for your eyes!

Back in 1992, Terry de Gunzburg a French make up artist, created this beauty staple that is so often referred to as the 'magic wand' because of its amazing effects, for Yves Saint Laurent. It quickly became an overnight sensation and changed the industry for ever. Talking to a magazine Terry commented "Back then no one had skincare in a click pen, now I'm very happy to have inspired all the other models." And Ms De Gunzburg has not stopped there; last year she invented 'Or De Rose' which kick started the trend for rose gold cosmetics. However Touche Éclat will always be considered as her greatest masterpiece! Proving how popular it is 20 years later it's used by supermodels, make up artists and a multitude of celebrities including Madonna and Lady Gaga.

So what makes it so special you may ask? Well although Honoured as the UK's number 1 luxury beauty product, it has been debated upon by the masses of fans since it was first released - the biggest misconception is that it is not a concealer! I repeat, NOT A CONCEALER! When I purchased my first Touche Eclat, I will admit I fell into the trap of thinking that a click of the pen would take away the edge of the remains of a late night from under my eyes, and although it does work rather well, it is not as full coverage as I would have liked. Instead it is classed as a highlighter. Now if your unsure what the purpose and job role of a highlighter is then let me explain, a highlighter enhances the features on your face, giving you a healthy glow by reflecting light off of the shimmery consistency - something like Benefit Highbeam or Moonbeam. However Touché éclat does not possess the normal characteristics of a highlighter - that's what makes it a special and unique beauty must have.

Personally I think the design and packaging is just as important as the product, especially with high end beauty bits - you pay that extra for a little bit of luxury and Touche Eclat does not disappoint! Encased in a gorgeous, glossy gold rectangular box, measuring roughly 4-5 inches in height with the simplistic design of just the YSL logo. Once you open the thin cardboard casing, the gold pen is presented to you, roughly the same size as a marker or felt tip liner. The whole blueprint is very minimal and unpretentious but very effective and stylish with the whole pen and lid being coloured in chic glowing gold - the only other colour to break it up is the black button on the bottom which is the click mechanism to distribute the product. Once you take off the gleaming lid, the application tool is on hand - a brush like device that aids easy application and helps to prevent over usage and any wastage of product. Once you click the bottom of the pen the product travels up and is dispersed through the brush so you can just apply to the skin straight away no need for an extra fuss or no fear of using too much!

To celebrate the 20th anniversary YSL released a new limited edition version entitled 'Tuxedo' with the same concept and formulation - the only difference being on the pen itself a long black line that turns into the letter Y on the lid is adorned. Although it was a limited edition, some online make up stores still stock it retailing at £25.

There are 8 consistent shades available not including the limited edition ones.
Shade #1 - The Original Highlighter - contains a little more shimmer.
Shade #1.5 - For fair complexions with golden and yellow undertones.
Shade #2 - For fair complexion with pink undertones.
Shade #3 - For olive and bronzed complexions.
Shade #4 - For medium to darker skin tones.
Shade #5 - For a warm tanned complexion.
Shade #6 - For a warm to dark complexion.
Shade #7 - For dark complexions.

So you may still be wondering what is so good about Touche Eclat and how do you use it. The main attribute is that the light around you does all the work to add a healthy glow to your skin, think of it as a mirror that reflects off of the unique 'Luminocaptide Complex' combined with other 'soft focus' pigments to provide an optimal level of light reflection to banish darkness and signs of fatigue. The radiance of your complexion is revitalised and refreshed adding a youthful sheer veil across the skin and any imperfections vanish with one swipe of the wand. Magic.

The texture and consistency is very creamy and suitable for all skin types as it is non drying and has oil control. The formula is transparent with the added colour of the shade you choose, it blends very well with all skincare products and make up. It does not cake or sit in lines so you can touch up your Touche as many times as you want.

You can use this wherever you feel you need to. However I tend to use it on these main areas; to hide fatigue I like to apply a few dots to the sides of my nose, under my eyes and the corners of my mouth and blend in well. To sculpt and highlight my face, I apply to the centre of my forehead, bridge of my nose and top of my cheekbones to make sure the light will hit the exact right places! To refresh my eyes and make them appear more awake I apply to the lids, brow bone and inner corners - the results are like a mini eye lift for a fraction of the price! Another idea is to enhance your lips, blend some Touche Eclat around your lips to make them more defined and add a touch to your Cupids Bow to fake fuller lips. You can wear this on its own as it has great staying power, however if you want a little bit more coverage I would apply some foundation. Although it is not labelled as a concealer I find a little under the eyes really does work wonders - I would not waste this on acne though. A real all rounder no wonder make up artists look for it more than a biro!

If you love Touche Eclat there is a foundation now available that may be of interest to you as it contains the same luminosity concept as the magic pen. Also of your boyfriend is eyeing up your highlighter you can stop him nicking yours as there is a Touch Eclat for Men available that is modelled by Stuart Pilkington - a Big Brother contestant.

This is a high end product and retails from £20 - £25, you can purchase in Boots, department stores, all good online make up stores, eBay and Amazon - just be careful to pick the right shade when ordering online.
