BAD. They are bad news. Every time you use it to cover a spot, you're rubbing the bacteria from that spot onto other parts of your face. Gross yeah?However, if you have bought one, do not despair. I've found that a stick concealer makes a great eyeshadow primer and they're much cheaper that the real thing. Under Eye Concealers
They can be tricky. The best one around is of course, Yves Saint Laurent, which is quite expensive but worth every penny. Natural Collection also do a version which I, being a penniless student, use. There's one pretty serious flaw with it though, no matter what number you buy, they're all the same colour. I bought the lightest one and it's still several shades darker than my foundation.When using under eye concealers, only use a rice size piece under each eye, then blend with a make up sponge/brush. Other wise it's just too thick and can look cakey and ageing. Palette Concealers
Again, they have the carrying infection risk. Always use a brush for palettes and clean they brush at least once a week.The big advantage of palette concealers is that there's lots of colours with different tinges and hues. A green tinged concealer is great for covering up redness while a salmon-y concealer will cover up purple blemishes like under eye circles.
I use this method myself, I definitely think it's the easiest and cheapest. You don't need tape or templates or anything fancy, just a base colour, a colour for the tips, clear nail polish and a steady hand.
Pros: It's cheap, obvz. I actually only bought this mascara in desperation because I needed one and had no money. I've found it really good. It lengthens and thickens. It's not clumpy once you apply it right, it doesn't smudge and it's easy to take off. The packaging is nice, simple and pretty.
Cons: The wand itself can get a bit gooey at the top, which means it's hard to do your corners. It also doesn't apply that well to your bottom lashes either, but that's a small consolidation.
Splurge:
Maybelline New York The Colossal Volum' Express Waterproof
Price: €7.93
Pros: As far as mascaras go, it's not that expensive. The packaging is also nice and futuristic. When they say water proof they mean waterproof, so if the summer ever comes this is a beach bag must have.
Cons: This has been voted the world's No.1 mascara and I can't understand why. It's clumpy and damn near impossible to get off, even with eye make up remover. It takes at least four coats to get it's full effect which means it doesn't last that long. It thickens lashes at the base but does little to lengthen. It also has a weird smell, kind of like play-doh.
The song itself is catchy but not great. But her make up is fantastic, I'm thinking of it for my debs. It's pretty much smoky eye 101. I'm sorry I couldn't find a clearer picture, but I did find a great tutorial that I hope is of help.
