Ok, I have the worst dark eye circles ever. AAAARRRGGHH. I hate concealing them every day. Has anyone tried the stivectin dark circle reducer or anything like it that actually works? I used biotherm hydra detox faithfully, but no results. Otherwise, which concealer works the best? I have very very fair skin (part of the problem) with pinkish undertones. I am a Mac NC20. I have used all the Mac concealers, but the dark circles always start to show through. Any input would be greatly appreciated.
