Professional visagiste apply various make-up techniques to visually enlarge lips. Here I got the tip revealing one of these secrets:

1. Outline the central part of upper lip (the one that looks like a tip) with pink lip liner. The shadow should maximally match the natural color of your lips.

2. Take light-brown liner and draw some shadow under the centre of lower lip. Thus you'll deepen the chin hollow and make the lower lip seem fuller.

3. Apply lip gloss with sparkles that will visually make your lips fuller.
