Smiling vs. Neutral: Which Works Better for Matches?
When it comes to dating profile photos, your facial expression plays a huge role in how others perceive you. Research shows that smiling generally leads to higher match rates, especially for people seeking long-term relationships. A genuine smile (one that reaches the eyes) signals warmth and approachability, boosting match rates to 34.2%. On the other hand, a neutral expression conveys confidence and works better for certain contexts, like projecting masculinity or maturity, with a match rate of 19.4%.
Key Takeaways:
- Smiling: Best for long-term relationship seekers; genuine smiles outperform forced or closed-mouth ones.
- Neutral Expression: Effective for short-term goals or when projecting confidence, but may seem less friendly.
- Photo Quality Matters: High-quality photos with natural expressions significantly improve engagement.
The choice between smiling and neutral depends on your personality, dating goals, and audience preferences. Tools like AI photo generators can help refine and test different expressions to optimize your profile.
Smiling Photos: The Friendly Approach
What Research Says About Smiling
Smiling sparks an almost instant reaction in the human brain. When someone sees you smiling, they’re likely to see you as approachable, warm, and sociable - this all happens in milliseconds [4]. That’s because smiling is a universal way to signal trust and cooperation [5]. In fact, nearly half of adults (48%) say a smile is the most memorable feature when meeting someone for the first time [7].
The numbers back this up. A massive study of 1.8 million dating profiles (spanning January 2024 to June 2025) found that users with genuine smiles - those that reach the eyes and create crow’s feet - had a match rate of 34.2%. Compare that to just 19.4% for serious expressions, and you’re looking at a 76% boost [6]. Dr. Anthony LaVacca from Naperville Dental Specialists explains:
A smile signals a person is happy, triggering a positive feeling in the person they're smiling at and informing how the receiver should respond to them [7].
But not all smiles are equal. Genuine smiles consistently outperform forced ones. Smiles that include crow’s feet are seen as 23% more authentic [6]. On the flip side, overly posed smiles perform the worst, with a match rate of just 16.2% - a 53% drop compared to genuine smiles [6]. The takeaway? A natural, heartfelt smile can make all the difference in how others perceive you.
When Smiling Gets Better Results
These findings aren’t just theoretical - they have real-world applications, especially for those seeking meaningful connections. Smiling is particularly effective when you’re looking for something long-term. Research shows that smiling enhances trustworthiness and overall appeal for individuals aiming for long-term relationships or marriage. A 2015 study published in the Evolutionary Psychology Journal revealed that women rated smiling men as more attractive in long-term relationship contexts [5].
For women’s profiles, the benefits are even more pronounced. Men consistently find smiling women more attractive than those with neutral or other expressions like pride or shame [8][11]. In one study focused on sexual attraction, men rated smiling women above 5 on a 9-point scale, while women showing proud expressions scored 1 to 2 points lower [11]. Dr. Jess Carbino, former sociologist at Bumble, explains:
Smiling makes such a significant difference... You want to come off as kind and approachable, which is what smiling projects [10].
A genuine smile can even offset less-than-perfect physical features, helping you stand out in a competitive dating pool [10]. For those seeking long-term relationships, the science is clear: a warm, authentic smile boosts trust and approachability, making your profile shine.
When Smiling Can Backfire
But smiling isn’t always the best choice. Fake or forced smiles (the kind that don’t reach the eyes) can come across as insincere, uncertain, or even deceptive [2]. As Professor Jan Erik Lönnqvist from the University of Helsinki notes:
Targets who displayed non-Duchenne (fake) smiles were generally rated less favorably than targets who did not smile or targets who displayed Duchenne (authentic) smiles [2].
Closed-mouth smiles, in particular, don’t perform as well. They lead to a 19% lower match rate (27.8%) compared to open, genuine smiles [6]. People with higher levels of Neuroticism or Conscientiousness are especially likely to respond negatively to inauthentic expressions [2].
For men, the impact of smiling can vary depending on the context. In situations where masculinity or dominance is emphasized - like profiles aimed at casual encounters - a wide smile might be seen as less dominant or "too feminine" [11]. Data from OKCupid shows that men who avoid smiling and look away from the camera tend to meet 0.2 more women per attempt than those who smile while looking away [12]. In one study, women rated smiling men a 3 out of 9 for "carnal" attraction, while men showing shame or pride scored closer to 4 [12].
If your goal is a serious relationship, a genuine smile is your best bet. But if you’re aiming to highlight traditional masculinity for short-term attraction, a neutral expression might work better. The key is aligning your expression with your dating objectives to make the strongest impression possible.

Neutral Expressions: The Confident Look
What Neutral Expressions Communicate
A neutral expression can send a completely different message than a smile. Where a smile radiates warmth, a neutral look leans into confidence and authority. It’s often tied to qualities like dominance, maturity, and capability [4][13]. For men, in particular, a neutral expression aligns with traits like toughness, power, and stoicism - hallmarks of traditional masculinity [4][13].
Tay Hack from Angelo State University explains this link clearly:
"Masculine stereotypes that describe men as competent, competitive, and stoic, implicitly dictate that men also should display behaviors that reflect agentic qualities." [4]
Beyond confidence, a neutral face can add a layer of mystery. Depending on your facial structure, it might even suggest shrewdness or an intuitive edge [13]. Interestingly, neutral expressions often score higher than forced or insincere smiles, especially among those who value authenticity [2]. So, if pulling off a genuine smile feels tricky, a neutral expression can be a reliable go-to.
When Neutral Expressions Work Better
Studies back up the effectiveness of neutral expressions. For instance, serious, neutral looks achieve a 19.4% match rate, compared to just 16.2% for overly posed smiles [6]. Pairing a neutral expression with a confident posture can also boost perceived attractiveness by 27% for men [6].
Neutral expressions tend to resonate more with older audiences (ages 35–54+), who often prefer a polished, mature aesthetic over casual or high-energy vibes [6]. In these cases, a neutral look communicates sophistication and refinement. Adding darker tones and a serious expression can amplify this effect, increasing perceptions of sophistication by 9%, though it may reduce approachability by 7% [6].
For men aiming to highlight traditional masculine traits, a neutral expression can strike a balance - projecting confidence and dominance without the overly friendly tone a smile might bring. However, while this approach has its strengths, it’s not without its pitfalls.
Downsides of Neutral Expressions
The flip side of a neutral expression is the risk of coming across as cold or unapproachable. While smiles are often linked to warmth and friendliness, neutral looks are judged more on competence and dominance [4].
Body language expert Angela Neik cautions:
"Using [a neutral] expression... may hinder those interactions, because people will read it as non-caring, and non-involved." [16]
Another challenge is emotion overgeneralization - when a neutral face unintentionally looks angry, sad, or fearful [13]. For instance, men’s neutral faces are often seen as “angry” or “dominant,” while women’s may be interpreted as “surprised” or “fearful” [13]. A tense neutral look - complete with a clenched jaw or furrowed brow - can unintentionally signal disinterest [15][16].
To avoid these missteps, experts recommend aiming for what’s called “engaged neutrality.” This means relaxing your jaw, softening your gaze, and smoothing your forehead [16]. Done right, this approach conveys confidence and maturity without veering into defensive or detached territory.

Direct Comparison: Smiling vs. Neutral
Dating Profile Photo Expression Comparison: Match Rates and Best Use Cases
Comparison Table: Key Differences
Here’s a breakdown comparing smiling and neutral expressions across various factors:
| Expression Type | Match Rate | Primary Perception | Best Use | Risk Factor |
|---|---|---|---|---|
| Duchenne Smile | 34.2% [6] | Approachable, trustworthy, signals reliability [3][17] | Primary profile photo to maximize matches | May appear fake if not genuine [2] |
| Closed-Mouth Smile | 27.8% [6] | Polite and approachable, but less warm | Secondary photos in a professional-casual setting | Lower engagement than a genuine smile |
| Neutral/Serious | 19.4% [6] | Conveys confidence and sophistication, yet less approachable [6] | High-status looks or confident poses (especially for men) | Can come off as aggressive or creepy [2][17] |
| Overly Posed Smile | 16.2% [6] | Appears inauthentic, as if trying too hard | Best avoided | Performs even worse than a neutral expression |
A genuine Duchenne smile stands out with a 34.2% match rate, significantly outperforming the 19.4% rate for a neutral expression [6]. When paired with professional-quality photos, the likelihood of a right swipe jumps to 67.3%, compared to just 28.7% for average-quality photos with a neutral expression [6].
Smiling doesn’t just improve match rates - it builds trust. Happy expressions are judged as more trustworthy than neutral ones, and this perception forms in as little as 0.3 seconds [3]. This trust factor can have real-world effects, influencing decisions like voting or loan approvals [3]. Interestingly, smiling also reduces reliance on stereotypes tied to race or gender during first impressions [1].
However, a smile alone isn’t enough. Photo quality and background also play a major role in how others perceive you.
Other Factors That Affect Results
Expression type is just one piece of the puzzle. Other elements in your photo can amplify - or diminish - the impact of your expression.
A high-quality photo with a genuine smile creates a halo effect, boosting perceptions of confidence and intelligence [6]. Keeping backgrounds simple helps, too. Minimalistic backgrounds increase match rates by 19%, as they keep the focus on your face [6].
Color choices matter as well. Blue tones enhance trustworthiness by 15%, while red clothing can increase perceived attractiveness by 18% [6]. For men, confident poses in outdoor settings result in a 27% and 29% boost in match rates, respectively. Women, on the other hand, see a 27% increase when using natural, candid expressions [6].
Preferences also vary by audience. Older users (ages 35–54+) tend to favor polished, neutral expressions [6]. Meanwhile, individuals who score high in neuroticism or conscientiousness are particularly sensitive to inauthentic smiles, often rating them more negatively than neutral expressions [2]. If you find it hard to produce a genuine smile, a neutral expression might work better for certain audiences.
The key takeaway? Align your expression with both your personality and the preferences of your target audience to make the best impression.
Using AI to Improve Your Dating Photos
How Dating Photo AI Works
Dating Photo AI makes creating professional-quality dating photos easy and fast. All you need to do is upload 6–8 photos of yourself - selfies, casual shots, or anything in between - and the AI generates dozens of polished images in various styles like Candid, Hobbies, and Travel [14]. The tool places you in different settings, from casual outdoor scenes to professional backdrops, while fine-tuning lighting and composition to highlight your best features. It’s designed to capture both natural smiles and confident neutral expressions, which studies show can improve engagement rates [14][6].
The key here is subtlety. Instead of making drastic changes, the AI focuses on refining the details - adjusting lighting, backgrounds, and framing - while keeping you fully recognizable. This avoids the overly edited, “too perfect” look that can make photos feel unnatural. Plus, the process is incredibly quick, taking just minutes compared to days with a traditional photoshoot [14].
Another advantage? The AI creates a mix of expressions, including genuine Duchenne smiles (the kind that light up your eyes) and poised neutral looks. This allows you to experiment and see which works best for your profile. Considering that 52% of swipe decisions hinge on the first photo, which gets only 1.9 seconds of attention, having multiple top-notch options can make a huge difference [6]. These small but strategic tweaks can directly boost your profile’s performance.
Benefits of AI-Generated Dating Photos
AI-enhanced photos can significantly improve your dating profile’s success. For instance, profiles with AI-refined images achieve a 32.8% match rate - 96% of what you’d get from professional photos costing $200–$500 - but for just $15–$40, making it a much more affordable option [6]. That’s a 272% increase in match rates compared to regular smartphone photos.
Here’s another standout stat: AI-enhanced photos are 21 times more likely to lead to an actual date [6]. While people often say they prefer “authentic” photos, data shows they swipe right 41% more often on polished, high-quality images [6]. And if you’re not satisfied with the results? Dating Photo AI offers a full refund if you don’t notice a significant boost in match quality or quantity [14].
It’s not just about match rates, though. AI photos can create a halo effect, making your entire profile - including your bio - come across more favorably [6]. This ripple effect can elevate how you’re perceived overall, aligning with findings on the importance of facial expressions. Plus, regularly updating your photos - ideally once a month - can increase your visibility on dating platforms by 28% [6]. With flexible plans starting at 40 photos and options for unlimited images with custom prompts, you can keep testing different styles and expressions to find what resonates most with your dating goals.
Conclusion: Choosing the Right Expression
Deciding between a genuine smile and a neutral look depends on your dating goals and personality. Research shows a genuine Duchenne smile achieves a 34.2% match rate, compared to 19.4% for a neutral expression [6]. If you're aiming for a long-term relationship, a warm smile helps convey trust and approachability. On the other hand, for short-term connections where projecting confidence or traditional masculinity is key, a neutral expression may resonate better with certain audiences [9].
The most important factor? Staying authentic. Fake or overly posed smiles drop match rates to 16.2%, and people can spot insincerity in just 0.3 seconds [6]. With 52% of swipe decisions based solely on the first photo, your image needs to feel natural and reflect who you truly are. The choice of expression should align with your personality and the preferences of your target audience, as discussed earlier.
Main Takeaways
Here’s how you can use these insights effectively:
- Lead with a genuine smile in your primary photo - it tends to attract the most matches across different audiences.
- Try different expressions to see what works best. Women generally prefer natural, candid photos, while men experience about a 27% boost in appeal with confident poses [6].

Plus, updating your profile regularly can increase visibility by 28% [6].
Ultimately, choose an expression that aligns with your goals, feels authentic, and leverages available tools and data to maximize your matches.
FAQs
How can I tell if my smile looks genuine in a photo?
A real smile, known as a Duchenne smile, lights up not just your mouth but your eyes too. Look for subtle details like crow’s feet around your eyes and a natural, effortless feel. If you want to check yours, try smiling in front of a mirror - do your eyes show joy, or does it feel stiff? Using high-quality photos that showcase this kind of genuine expression can make your dating profile more inviting and relatable.
How many smiling vs. neutral photos should I include on my profile?
Experts suggest including 4-6 photos on your dating profile, balancing both smiling and neutral expressions. Your first photo is especially important - it should highlight a genuine smile and direct eye contact. Why? Smiling can boost perceived warmth by over 20%, according to research. Combining this with a mix of expressions not only adds depth to your profile but also makes you seem more real and approachable, increasing your chances of making meaningful matches.
What quick tweaks make a neutral expression look less intimidating?
To make a neutral expression feel more inviting, consider small tweaks like adding a soft, genuine smile to show warmth. Relax your facial muscles and avoid any tightness or stiffness. A gentle gaze or slightly raised eyebrows can also make a big difference. These subtle adjustments can help your expression seem friendlier and less intimidating.
