How do you define a sexy mouth?

Angelina Jolie has women rushing to the plastic surgeon for collagen lip injections in order to get big mouths or pillow lips like hers. Full lips are sensuous.

Yet in eastern cultures, small mouths are considered feminine while big mouths are thought of as uncouth. Hence you see the tiny mouths painted on the faces of Japanese geishas.
The geisha would paint her entire face, including her lips white. Then she would paint a tiny scarlet mouth on her lips, making her mouth appear far smaller than it really is.

Women of all cultures use makeup to create sensuous mouths according to their culture's definition of sexy.

No matter what the culture, smooth rosy lips are considered beautiful.

To get your lips as beautiful as nature intended, moisturize and exfoliate them.

Here's a simple lip exfoliating scrub you can use to get your lips rosy and smooth.
1. Mix 1 teaspoon of honey with half a teaspoon of raw sugar.
2. Apply the mixture on your lips.
3. Leave it on for 5 minutes.
4. Gently massage lips with clean finger tips.
5. Rinse off the scrub with plenty of water.

After using the scrub, apply a rich lip balm to moisturize and protect your lips.

Actually, to keep lips soft and kissable, keep them moisturized at all times. Use a lip gloss or lip balm all day long, reapplying whenever lips feel dry. At night, before you sleep, apply a rich lip balm or vaseline on your lips.

If you feel bare without makeup, but prefer that naturally pretty look lip gloss gives you, layer 2 lip glosses for depth, so that lips look fuller. More sensuous.
Apply a rosy lip gloss 1 or 2 shades darker than inside your cheek.
Apply a dab of a pale, shimmery, pink gloss over the center of your lower lip for depth.
Voila. Your lips look instantly fuller, prettier and more sensual.

If you really want to vamp it up, go red.
Crimson lips are downright sexy.
1. Line lips with a nude lip pencil to keep lip color from bleeding.
2. Paint the lipstick on the lips with a lip brush.
3. Blot with kleenex and powder lips with a translucent powder.
4. Paint another layer of lipstick on lips with the lip brush.
5. Add a touch of shimmer on the center of the lower lip.

Want even fuller lips?
If bee stung lips like Ms Jolie's are your obsession, you might want to visit the plastic surgeon for collagen injections to plump up your lips.

If that is too drastic, try a lip plumper.

Some lip plumpers, like Duwop lip venom use essential oils to mildly irritate the lips so that they swell up.
The newer ones, like Lipfusion use dehydrated collagen to plump up the lips once the formula is absorbed through the thin skin of the lips.
