Did you try the Garnier Dark Eye Circle pen thingy...its like 20 bucks++
Just a suggestion..

been battling dark circles since my teen years.... unfortunately the truth is it comes down to genetics...

Of cos, to start of with drinking lots of water and having enough sleep...

Dark circles look worse if you have bags to go with it... unfortunately i have that too... not drinking too much water at nite and some cold bags of tea or cucumber in the morn helps a tiny bit, but in essence, something cold with constrict the skin and make your bags less apparent...

Only way to really remove bags - go for cosmetic surgery to remove excess skin under your eyes when you're hitting your 30s or 40s. No products can save your bags, it's just plain genetics..

Concealer will be your best friend

First concealer I tried many years ago was the Clinique Pen thingy (cant remember name anymore) was alrite, need retouching (used this for few years)

Then experimented with a few but these never stuck with me
Maybeline yellow corrector stick (so cakey)
Loreal True match (too watery, does nothing, color shades are off)
Stila - if u love obvious creases
Mac - doesnt last long, just brightens but still can see purplish shade of dark circle
Stage - Almost like a MAC rip-off. Works almost as well but not quite.. results will show
Estee Lauder - So-so, can't cover as well as Bobbi.

Bobbi Brown until recently - Used this for the last 5 years. Corrector is key, hide the circle then use a concealer shade which is not too white looking for ur face.  only wished they have customizable palette to put both corrector n concealer + loose powder altogether than carrying a few jars around. They had one palette like 5, 6 or 7 years ago which has corrector, concealer, foundation, loose powder n a mini brush with puff. Wish they do that again. Only drawback- a few steps.. wish i can just dab smth n be done... A bit rich, will crease a tiny bit towards end of the day. Will need touch up but not as often as some I tried

Now experimenting with Benefit Boi ing - Impressive I must say.. I've shunned so many concealers over the last 10 years. Boi ing mimics the yellow undertone that Bobbi Brown shades has so it compliments ur skin. It doesnt cake up at all and it covers so well without a corrector. No wonder it's called Industrial Strength.... Only thing is that you prob need to puff some loose powder on it to make it stay..  wish it was bit cheaper though....

Can compete with Bobbi Brown's which I have been so loyal to for many years!

Anyone else tried Cle de Peau is amazing but I don't know where I can get it here and heard it's pricey too. Any experiences?
