When you're as haggard and woe begone as a Keats poem, you need all the 'anti-fatigue + radiant glow' you can possibly find. Rimmel were kind enough to whack such a thing in a tube with a fluorescent cap bright enough to wake even the walking comatose, so let us forgive them for the homage to Wham!
Wake Me Up concealer is a bit of a multi-use product. It is a luminescent, thin consistency which lends itself perfectly to concealing and brightening the under eye and redness, and doubles as a very nice highlight for between my brows, down my nose and on my chin. It has the right amount of coverage without the cake, however I wouldn't even consider attempting to conceal blemishes with it. Let's be real, no one ought to highlight a pustule.
For under the eye in particular, this is pretty phenomenal and lasts all day. One thin layer, patted out with the ring finger sets demi-matte and lasts nicely, though Wake Me Up is by no means a heavy duty concealer. I'd say it's comparable to the much loved Maybelline Instant Age Rewind, only more brightening as it does contain miniscule flecks of shimmer, nothing scary though. I also find it to be superiorly sanitary with the good ol' fashioned doe foot respectable receptacle.
Lastly, before you go go and leave me hanging on like a yo yo, Rimmel are exceptionally reasonably priced and are dependable to go on sale frequently. I highly suggest giving it a whirl.
