so here is a tutorial on some tricks that I have learnt on making your lips bigger & fuller.
|Before & After. I think my lips look a little too porn star like though ;) You don't have to agree!Sorry that it goes off into the sidebar (on my computer anyways) to view properly, left click on it & it should open a new window|
So yeah thats basically it, you can tweak it for your needs. I suppose I didn't need to use the highlight on the bottom lip. & honestly, using the mauve lip liner just on the inside may not seem like it does much ( When I was doing this I thought I would see how it turned out & I believe it helped) but try for yourself! Look back at the top pic :)
UPDATE: I tried this with pink & it turns out that I think you should do the first step with a same colour as your l/s but do it after you have applied the l/s!
