As we age, our lips lose some of their fat. Here’s how to plump up thin lips. Skip bright colors & opt for a shade or 2 darker than natural lip color. •Create a lip line by coloring in lips 1st w/liner, then apply gloss or lipstick over liner. •Consider getting rid of lipstick & using lip gloss instead. Gloss creates the illusion of full lips. •Lip plumpers do work, but the effects don’t last long. So skip them.
