Flash balm doesnt do anything for me either, I have got some 8 hours cream - been using the same tube for about 10 years! I go through phases where I use it a lot then dont touch it for months. I've certainly never worn it on my eyelids or cheeks like the mags all used to say the celebs did!
I had a mini tube of 8 hour cream which I got for free and it is good for using on my lips but I wouldn't bother buying it.
A friend got me a voucher for a Clarins facial and I was able to redeem the price of it against products so I got the Flash Balm as read so many raving reviews. I wasn't that impressed with it - never really seemed to do much for me so I ended up getting rid of it. Won't bother with that again - there are similar products which work better on my skin and are cheaper.
