It's a close call on whether or not you like your driver's license photo. Perhaps you blinked, didn't hear your cue, or could it be that a double chin just appeared out of nowhere? These mishaps can happen in any type of photo, not just the ones that prove you can legally operate heavy machinery.
To avoid the photo double chin, stand tall, hold your shoulders back, and stick your chin up just slightly. Better yet? Use this technique that my mom taught me.
Simply touch the tip of your tongue to the roof of your mouth and smile. This action helps muscles tighten around the neck area. That, and, it instantly makes you more aware of any inadvertent slouching. Say cheese — hold the extra chin.
