From runway to rock fest: Here's how to make the tiny face-tat trend (summer's outdoor-concert essential) work for you.

1. Make the skin matte.

Opt for oil-free everything lotion, sunscreen, concealer, foundation and set with translucent powder.

Sketching on dewy or sweaty skin is a one-way ticket to Smudgeville.

2. Practice makes perfect.

Test your design (such as the heart or moon on the models, here) on paper or your hand first.

Ready for your face? A stable arm is key.

Suzy Gerstein, a New York City-based makeup artist, recommends propping your elbow on a flat surface and keeping it as close to your body as possible to reduce shaking.

3. Pick the right pen.

A fine-tip liquid liner pen is clutch for drawing thin lines, while one with a rounded tip is best for dotting.

"Start small, and step back from the mirror periodically to make sure you like what you see," says Gerstein.

"You can always add more."

4. Clean it up.

Wet a cotton swab with makeup remover to spot-erase messy or wiggly lines.

Keep some on hand throughout the day for touch-ups.
