Concealer is not the only way to fix complexion flaws. Try wearing lipstick in a warm pink shade. It distracts people's eyes from blemishes or other imperfections.
Looking tired and need to look refreshed? Avoid foundation and use a tinted moisturizer instead, followed by a beige eye pencil to counteract any redness around your eyes.
Keep your eyes open when applying liquid liner so the line does not appear uneven. Draw three dashes, one on the corner, one in the middle and one on the inside corner. Then go back and connect the dashes.
For full lips with a glossy look try first outlining the perimeter of the your lips with a concealer brush dipped in a bronzer two shades deeper than your skin tone. Then top with gold, peach or coral gloss.
