I'd like to recommend a good value dark circle concealer.

It is the Skinfood Salmon Dark Circle Concealer. I am using shade #2, and I believe it comes in shades #1 and #2! I have struggled a lot with dark circles, so I have tried various color correctors and many different brands. However, the Skinfood concealer I am currently using is cost-effective and covers them quite well, so I find it to be a solid choice. My dark circles tend to be darker rather than bluish, so conventional concealers are too light and skin-toned to cover them at all. I can only cover them with a shade that has a slight orange tint like that. I recommend this to anyone who struggles with dark circles like me.
