What is the purpose of wearing lip liner?

To fix whatever's wrong with themWhat is the purpose of wearing lip liner?
Serves two very good purposes:


1.) Defines the lip. You can actually use liner to either exaggerate or minimize your lips- the trick is in both how close to the edge of your mouth you line, and also with what color. Too dark pretty much always looks bad- unless it is covered with a great-staying lip color that complements it (or if you like the extreme look).





2.)Keeps lip color from spreading. It even works to keep gloss in place- and in fact when you wear lip liner, you're much less likely to lick your lips or rub them together (since you're aware of impending smear doom if you do), so gloss will stay shinier and unlicked for longer than five minutes*
Lip liner helps to make the lipstick stay in place and not ';run';





It also, if used correctly, can make your lips look fuller, more shapely..etc... I stomtimes use a darker shad of red for the liner than my lipstick or my lips(not like black) but a darker shade gives your lips dimension. When you used the same exact color as your lips or lipstick its great but doesnt create much of an effect.





So it all depends on what you are looking for...either way any time i have lipsick on I use lip liner.
Lip liner is generally used to block Lipstick from running or seeping into the smile fine lines some get around the lip area, of course you can also use it to shape or perfect your lip shape!!! it should usually be the same color as your lip or as you lipstick!!!
It's used for both. It outlines your lips to make them appear thinner or smaller. Sometimes you may have an uneven lip so you line your lips a little higher or lower on one side of your lips. Just depends on your personal preference. You don't HAVE to use it but sometimes it helps.
bigger.... i dont think it looks good when there is like a black line around them, that looks trashy i agree with you, but when its pretty much the same color as the lip stick/gloss, its to make them look bigger.
I have no clue what the point in wearing it is! I've always wondered that too. I have worn a light pink lipliner, but only because it stayed on better than lipstick.
sometimes it is used to keep lipstick from running out of the lips smile lines and other times it is used to give you a more poutier look
usually bigger but some women do use it to make their lips look smaller.
I don't think it looks good on anyone and I don't know why people wear it. I wouldn't recommend it to anyone.
