Other Tricks
Keeping your lipstick put
First thing you should do to keep your lipstick put is to apply a base which keeps the lipstick put. Most make-up brands make at least one of these. The next thing you can do is to blot your lipstick a little after it's been sitting on you lips for a minute. Also to keep color lasting longer apply lip liner to the whole lip before applying lipstick.

To have a glossy or wet look do not apply gloss to the whole lip apply it only to the middle inside part of the lip. Then gently press and rub lips to spread the gloss outwards.
