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. Lipstick will last longer if you 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. Beauty editors know you can create a great lipcolor by combining lipsticks you don't like. 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. 'Nuff said.

Tip #11: Keep lip gloss on longer with liner. Lip gloss is infamous for wearing off fast, but if you fill in lips first with the liner, the gloss has something to stick to.

Tip #12: Heal -- don't throw out -- a broken lipstick. If your lipstick breaks off, simply take off the broken portion with a tissue, then slowly wave a lit match under the broken piece of lipstick. When it's melted a bit, put it back on the base, swivel it down and put it in the fridge -- uncovered -- for 5 minutes.

Tip #13: Avoid orange or brown shades. They tend to make teeth appear yellow.

Tip #14: Save the last bits. Down to the last bit of you favorite lipstick? There's plenty more at the bottom of your tube. Scrape out the last bits with a cotton swap or orange stick & mix it with Vaseline or lip gloss in a lipstick palette.

Tip #15: Keep lipstick off glass. Discreetly lick the lip of the glass before touching your lips to it. It works!
