Line lip with lip-liner that is brighter than the lipstick you are using. This will make the lipstick P O P more. I am using REDD by MAC.
 Fill in your lips w/your lipstick of choice; mine is Ruby Woo [of course] - Don't worry about getting it perfect; you can fill in any areas w/your pencil/lip-color later.
 I apply my concealer w/a stiff, flat brush. I use NW45 concealer, and I pat it around the lip area; very close to the lip line.
Be sure and get as close to the lip-line as possible! This will make the color pop even more! Applying it with a brush is much better than applying the concealer w/your fingertips [as far as accuracy is concerned].
