The texture is incredibly thick for a concealer, meaning you need a really small amount to cover under-eye areas effectively. It's best to build coverage gradually so as not to overload the area, adding a touch to the outer edge first and blending it inwards. This really does cover dark circles without caking or sitting in fine lines, leaving skin looking radiant; it has a subtle glow that really catches the light and brightens an otherwise dark crevice.
It works just as well being applied with a finger as it does with a brush, but buffing it a little into skin will help remove any imperfections that may creep up on you within an hour or too (as it starts to dry and slightly sit within fine lines.) Although I wouldn't say it's the best concealer in the world, it definitely comes close. At £19.50 for a tube that will last for an incredibly long time, this is one product I'd definitely invest in this payday if your under eye circles are crying out for help.
The Amazing Cosmetics concealer is currently available exclusively in M&S beauty halls nationwide, as well as online, priced £19.50.
