How to Smile for a Headshot: Tips for a Natural, Confident Look

Your smile is the first thing people notice in a headshot, and a forced one can undermine an otherwise great photo. The difference between a smile that feels warm and one that looks uncomfortable comes down to technique, not luck. This guide covers the science behind natural smiles and practical methods you can use during your next headshot session.
Should you smile in your headshot?
1. Smiling increases likability and trust
Research consistently shows that people who smile in professional photos are rated as more approachable, competent, and trustworthy. LinkedIn profiles with a genuine smile receive significantly more connection requests and profile views. Unless your industry specifically calls for a serious expression, a natural smile is almost always the right choice.
2. Industry matters
Corporate and business professionals benefit from a warm, approachable smile. Actors need range and often submit both smiling and serious headshots for commercial versus theatrical casting. Lawyers and executives sometimes prefer a confident, closed-mouth expression that conveys authority. Think about what your audience expects to see.

3. Understand the Duchenne smile
A Duchenne smile engages both the muscles around your mouth and the muscles around your eyes (the orbicularis oculi). This is what separates a genuine smile from a polite one. When only your mouth moves but your eyes stay flat, people instinctively sense the smile is forced. The key is to activate the muscles that create crow's feet at the corners of your eyes.
4. Engage your eyes, not just your mouth
Photographers call it a "smize" and it simply means letting warmth reach your eyes. Try slightly squinting your lower eyelids while you smile. This subtle contraction signals genuine emotion to the viewer and makes your headshot feel alive rather than staged.
5. Think of someone you like
The easiest way to produce a real smile on command is to think of a person who makes you happy, a funny memory, or something you are genuinely excited about. The emotional response triggers a Duchenne smile automatically. Professional photographers often chat with subjects between shots for exactly this reason.
Teeth or no teeth?
6. When to show teeth
Showing teeth creates a more open, energetic, and approachable impression. It works well for client-facing roles, sales, marketing, and anyone whose job involves building rapport quickly. If you are comfortable with your smile, showing teeth almost always reads as more genuine than keeping your lips closed.
7. When a closed-mouth smile works better
A subtle, closed-mouth smile conveys confidence, calm authority, and professionalism. It is a strong choice for executive headshots, legal professionals, and finance roles where approachability matters less than credibility. A closed-mouth smile also hides dental concerns if that is a source of self-consciousness.
Techniques to nail your smile on command
8. The exhale method
Take a deep breath in through your nose, then exhale slowly through your mouth while letting your face relax. At the very end of the exhale, let a smile form naturally. This technique releases tension in your face and jaw, producing a relaxed expression that does not look forced.
9. Say specific words
Words that end in a long "ee" sound naturally pull your lips into a smile shape. Try saying "money," "happy," or "easy" softly under your breath just before the shutter clicks. The resulting mouth position looks natural because it mimics the mechanics of a real smile.
10. The burst technique
Instead of holding one smile for multiple shots, reset your face to neutral between each frame and then smile fresh each time. This prevents the "frozen smile" that becomes increasingly stiff over time. Ask your photographer to shoot in bursts so they can capture the most natural moment as your smile forms.
Mistakes that ruin headshot smiles
11. The forced grin
Pulling your lips too wide creates a tense, unnatural look that viewers immediately recognize as fake. A good smile is moderate in width and reaches the eyes. If you feel like you are showing too many teeth or your cheeks are trembling from effort, dial it back. Less is more.
12. Tension in the jaw and neck
Clenching your jaw or tightening your neck muscles is a common stress response during photo sessions. This tension travels upward and flattens your smile. Before each shot, consciously relax your jaw by letting your mouth hang open for a second, then gently close it and smile. Roll your shoulders back to release neck tension.
