Tip #1: Store lipstick in the fridge. It will last weeks longer.
Tip #2: Never use a tester on your lips. It's just plain unhygienic. Instead, test lipstick on your fingertips. It's a closer fit to your lips than the back of your hand.
Tip #3: Use liner on your lips as a base. Want lipstick to last longer, than fill in your lips with the liner first. If you're using light lipstick, try a nude liner. Then slick your lipstick on top. Tip #4: Don't skip the liner. Without the prerequisite liner, your lips will look "smudgier" according to Berg, softer & less defined. Tip #5: Keep lipstick off your teeth with this trick. This is a trick I learned years ago from my mom. After applying lipstick, take your index finger & pop it in your mouth, then pull it out. The excess lipstick will come off on your finger rather than your teeth.
Tip #6: Lipstick can act as a blush. But never use blush as a lipstick.
Tip #7: Apply liner first. Lipstick tends to feather if you apply liner second. Also, you won't be able to see the natural line of your lips if you apply lipstick first.
Tip #8: The older you are, the 'creamier' your lips should look. Women over 50 should avoid matte or a gloss and stick with a creamy lipstick. Tip #9: Don't throw out a bad color lipstick. Instead, use other colors to perfect your own shade. You can also color in lips with a darker liner before applying a lipstick that's too bright.
Tip #10: For 'plump' lips, apply liner just outside your natural lipline.
