Aside from acne, dark circles has got to be one of the top things that women want gone from their faces. I wish there was a magic wand for this, for a lot of things actually, but there just isn't.
Dark circles can be caused by a few things, genetics, not enough sleep or in extreme cases, kidney disease. Trust me, if you have kidney problems, dark circles aren't going to be your first symptom of it.
Aside from some really great concealer, the ONLY thing that I have personally come across, that actually works, is...drum roll please......
I struggle with recommending Green Juices only because they are "cold" in nature and shouldn't be had by anyone with these symptoms: post nasal drip or phlegm, feeling cold all the time, lethargic, or bloats easily. This is just the acupuncturist in me, not wanting anyone with those symptoms to go on a green juice cleanse because it'll make those symptoms worse.
But, if you don't have any of that going on, the facialist in me recommends, having warm water with the juice of half a lemon as soon as you wake up, followed by the green juice. Wait a couple hours to have breakfast or just skip it, have well balanced meals for the rest of the day. The dark circles should clear up in a couple of days. I recommend it to all my brides and pretty much everyone.
Here's my fave "Banish the Dark Circles" Green Juice recipe:
1 green apple
Drink it the moment you make it or store in a glass jar (be sure to fill it all the way up to the lid of it will get oxygen in it, making it no good)
By all means, if you try this, let me know how it goes!
