1. The overly smudgy dark, smoky eye:
For a flawless way to do dark eye makeup, Johnson recommends using two eyeliners. Start by dotting on a dark liner to the base of the lashes. Then, simply go back over the line with a gel liner or dark shadow. Just by retracing the line, you'll get more intensity, help keep your makeup in place, and your lashes will look thicker.
2. Concealer and makeup overload:
An overabundance of concealer (or any other makeup product, for that matter) can look harsh on the complexion. So think of it this way: "Foundation really should do most of the work, and concealer should be an afterthought," Johnson advises.
3. Too much glitter and shimmer:
"I think glitter has its place," says Johnson, but she also notes it can be a bit much when applied to too many features. For a flattering way to do shimmer, Johnson recommends dabbing on a little highlighter on your cheeks or on the inner corner of your eyes to brighten.
