Store not only perfume in the fridge to make it last longer,
but also your lipstick...

Break off the lipstick from the tube? Heat the end of the broken
part of the lipstick with a lighter or match until soft, place it
back on the broken piece in the tube, put it in the freezer, and
it will be good as new...

If you want your lipstick to last longer on the lips, use a lip
pencil as a base on the lips. Outline and then color in the lips
with the pencil. If you like to wear light colored lipsticks,
use a nude pencil. Afterwards, color your lips with your lipstick...
