Colour Correcting could be your best friend or worst enemy... depending on whether you know how to apply it or not.
Sometimes, foundation and concealer just don't cut it. No matter how much coverage you layer on, stubborn dark under-eye circles, redness, and acne scars can still show through.
First, identify what you want to correct. Ask yourself: Are you getting what you want with your concealer and foundation? If the answer is no, then that means a corrector could help.
Secondly, and this is the biggest mistake I see, colour correcting products should be used minimally. I repeat, MINIMALLY! Instead of painting your entire face like you're about to go into combat, colour correcting products should only be used so that they just cancel out what you're trying to neutralize.
