For a dark color it's almost a must if you want it to look it's best. A lip crayon helps define and correct the shape of the lips but also works as a barrier preventing the lipstick to bleed and look all smudgy.
Now as I've said I haven't use one in ages due in part to the fact that I don't wear dark colors anymore and I don't really have bleeding problems with the lipstick formulas I wear.
It's not the same with lip glosses! They make our lips shiny and pretty but wow can they bleed and this happens even on young firm lips.
The solution... A clear lip liner!
You may have overlooked these, maybe even wondered what they were for well you now have your answer!
A clear lip liner is perfect for lip glosses and also for when you can't seem to find the exact same color as your lipstick.
Here are three different options...
Urban Decay $23.00
Maybelline under $10.00
I will be getting one of these real soon since I'm hearing a few of my lip glosses complaining about the lack of love they've received recently.
