When it comes to looking for the 'perfect concealer' I like to look for four particular things; the shade, coverage, texture and blendability. For the under eyes I like something that is one shade lighter than my skin tone so something that is considerably cool or neutral toned. I also don't like anything too thick as it creases and settles into fine lines easily so a concealer with a light to buildable coverage is a must. When it comes to disguising my flaws of course I like to have a lot more coverage, preferably medium to full, but with a creamy formula. I'm not fussy, I promise. I guess you could say I'm rather particular about what I like.
One that I have used for so many years is the Collection Lasting Perfection Concealer(£4.19). It is the most affordable concealer I have used, costing just under £5. I have the lightest shade, Fair 1 which is pretty much a perfect match to my skintone but there's also another three shades in the range for medium-warm skintones too. Unfortunately it isn't one for the under eyes as it feels slightly too thick and it creases quite badly underneath but due to the high coverage it does a fantastic job of covering up redness, acne scarring and spots. It lasts quite well too, although I can't be sure if it lasts up to it's claims of 16 hours as I never wear makeup for that long. It does last at least a good 8 hours though which is pretty impressive for the drugstore.
