I have trouble with dark circles and part of it is genetic, maybe allergies since I have those too. But if you're like me, you don't care if they're due to things you can't change...and you just want to know what to do about them. Mine aren't little dark areas close to the nose either - we're talking dark circles all the way from corner to corner of each eye. Ugh.
I abandoned all the creams and things to supposedly lighten about 6 months ago, and just started using Retin-A on the undereye area. At first they looked worse than before, but with continued use, some improvement (Retin-A stimulating collagen maybe?). I also started using a copper peptide serum (the Skin Biology brand). THAT made a big difference I believe. It could have been cumulative with the daily use of Retin-A and the periodic glycolic and/or TCA peels I started...but when I use copper peptides..the skin seems to tighten and tone and turn opaque again..not blue/green and dark! Yes I still have dark circles, I don't look like my 15-yr-old daughter, but they are much, much improved. I know this because of the amount of concealer I use.
This bring up the other part of controlling dark circles - coverage. I own probably 20 types of concealers, from Wet n'Wild to MAC. They either crease, clump, or just don't have the pigment needed. I've tried loading on moisturizer before the concealer to keep it from sinking into wrinkles..nothing works for long if it does at all.
But, I found a theatrical make up called Ben Nye - and they have a neutralizer concealer wheel (4 colors with yellow, orange, green, and bluish toned concealers) that has been amazing. A wheel is about $10, and by patting this on the under eye area first...then following with a liquid concealer of choice (cheap has worked great), and powdering immediately, it stays put and doesn't crease or sweat off. I swear by the Ben Nye stuff now...and you can check out reviews of Makeup Alley.
Lastly, this girl
has wonderful makeup tutorials...and I have been using her method of applying concealer to hide the dark areas. Maybe this will help you deal with these circles...as they are such a pain!!! Good luck!
