Olivier Echaudemaison, Creative Director at Guerlain, says: "If you only use one beauty product on your eyes, go for mascara. Brown is perfect for daytime, and black for going out. Slightly more unusual colours such as pink, emerald green and electric blue are also an option for young women. If you're a bit more mature, they can make your pupils look dull and can look a bit trashy."
Finding the right one
Decide what you need most: volume, length, or curl. You can't get all three in one mascara, so choose carefully!
Be aware of optical effects:
> If you have fine lashes, use a lengthening mascara, but remember that the longer your lashes, the thinner they look, so go for a volumising one too!
> If you have short lashes, go for a volumising mascara and remember that the larger your lashes, the shorter they look, so go for a lengthening one too that separates your lashes out well (like a false-eyelash effect).
> If you have fairly ordinary lashes, go for a curling mascara so there's no need for eyelash curlers!
Waterproof mascara is great if you're going to be exercising or if your emotions could get the better of you on big occasions! Waterproof doesn't run when it comes into contact with tears or water, so you don't have to worry about panda eyes. However, don't use waterproofs all the time: like hair dye, they can damage your lashes.
The best ones to use are water-soluble mascaras (try Clarins or Benefits).Apply your mascara from the base of your lashes and stretch upwards to the tips. For your top lashes, incline your head backwards and look down; for your lower lashes, tilt your head forwards and look up. Go easy on your lower lashes so that you don't weigh your eyes down.
Patrick Lorentz, Estée Lauder: "I never apply mascara to thin, sparse lower lashes because it makes them really obvious, and can also highlight bags or dark circles undeneath the eyes. Don't attract attention to your weak points!"
Should you wait until the first coat is dry before applying another one?
Patrick: No, otherwise your lashes will stick to your brush. Do one eye at a time and don't go back afterwards!
Is it a good idea to coat your top lashes from above and from underneath for a more glam effect?
Patrick: Some make-up artists do it, but you have to be careful because it can make your lashes drop. It's risky!
If you mess up, what should you use to remove spots of mascara?
Patrick: It's best to let it dry and then scrub it off gently with a brush so it turns to powder. If you still have marks, apply a bit of neutral eyeshadow over them.
James Kaliardos, L’Oréal:
Go from the base of your lashes so that you enhance your roots. Lifting the upper eyelid with a finger, brush under and then apply your colour. Don't put too much on your brush otherwise you'll end up with a heavy look, and start from the roots to get a black line - it's more dramatic. Don't go over the top on the ends if you don't want a spidery look.
Patrick Lorentz, Estée Lauder:
You want your lashes to be like your hair when you've been to the salon: well-separated out at the roots, with glossy tips! To get it right, you need to angle your brush so that you can put your hand on your jawbone. Don't be afraid of putting your brush right in your eye! Tilt your head backwards, and then apply small touches to the roots before zig-zagging over the whole length.
