A little product goes a long way. I have tried many high-end concealers to cover up acne scarring and redness, and the Insight Cosmetics Concealer in the shade of Siena Red by far has the fullest coverage. It lasts long enough through my shifts and covers any traces of tiredness around the eyes. It gives me a flawless and even complexion by blurring out blemishes and concealing dark circles, including redness. There are 6 choices for shades, which helps to get the perfect fit.
