This is a common problem with a very simple solution: Go to a makeup counter and get matched up with a formulation through a thorough pro's help! "Foundation is one product that you must try before you buy," says makeup artist Lori Hamlin Penske. Complexion can have different depths and undertones. The same goes for foundations. Once you determine the tone of skin tone, you simply need to find the depth of color that matches best. The easiest way to find a match is to pick a few shades and apply a dab of each (in a row) along the jawline. "You must check the match in natural light. Don't be afraid to go outside with a mirror before purchasing!"

You use your brushes daily, but how often do you give them an important cleaning which they actually need? And when's the last time you got a new set of efficient, fluffy brushes? Dirty brushes are riddled with breakout-causing bacteria — and that's just one of the gross things that happens when you don't wash your tools. Then there are old, scratchy, dirty brushes, which can negatively affect your skin and your makeup application. "Try washing them in a nourishing soap. If that doesn't work, buy some new ones," says makeup artist Katie Jane Hughes. After all, great application brushes are worth the splurge.

While the thought of lip liner probably conjures not-so-fond memories of nude lips and dark liner, a lip pencil — when used properly — can actually help define your pout and prevent feathering. As evidenced by the early 90s, wearing darker liner is a massive mistake that will make you look both dated and, well, tacky. "The trick is to use a pencil that matches your lip color," says Penske. "Then apply it all over your lips. Not only will it make your lipstick appear more natural but it will also help it last longer." Similar hued lip pencils work wonders as they stubbornly add a pop of color even after you have eaten something or without any reapplication.

According to Hughes, using too much powder can enhance flaws and age your face really fast. "I often find that women with oily skin, in particular, tend to touch up their makeup with powder throughout the day," says Penske. Powder mostly accumulates. So, when you apply it to shiny areas it actually makes makeup look heavy and cakey rather than flawless and can give your skin a grayish tone. She suggests using oil-absorbing sheets, like Shiseido Pureness Oil Control Blotting Paper or Boscia Black Charcoal Blotting Linens, to combat shine and freshen your makeup and only use your compact when you are looking to add more coverage.
