There are several ways to make >lipstick last...that's just one of them
and it does work. You can also put >a minute amount of foundation on
your lips right before you apply your >makeup.
I've found the applying foundation as primer for lipstick automatically
changes the color of the lipstick, and generally not for the better.
I've never found a way to make this technique work.
OTOH, there's an elaborate procedure that can help lip color stay put
longer (outside of using one of the longlasting lip products):
(1) Line and fill in lips with lip pencil.
(2) Apply lip color carefully, preferably using lip brush.
(3) Blot gently but firmly (tissue between lips, press lips together).
(4) Separate tissue and gently place one "ply" over lips.
(5) Using a thick powder puff, press loose powder onto lips *through*
the tissue.
(6) Apply lip color again.
No, it won't last forever but definitely longer than just one coat of
lipstick alone.
