We all want glowing, youthful skin. But certain habits can sabotage that fresh look—even ones as innocent as chewing a stick of gum. People worry that chewing gum could be giving them smile lines or making existing wrinkles worse. As a chewing gum expert and copywriter, I get this question surprisingly often. So, is this habit really aging your face in secret, or is it all hype? Let’s dive into the facts.

The short answer: Chewing gum itself doesn’t directly cause wrinkles. But the repetitive motion of chewing—especially if you do it all the time—can make fine lines around your mouth and jaw appear sooner. If you chew gum in moderation, you probably don’t need to worry. Overdoing it every day might cause some minor issues over the years.

I know that sounds like a mixed answer! Wrinkles are a big deal, and no one wants to speed up the process. That’s why I’m breaking down the science and sharing my own expert take. Stick with me—I’ll unpack what actually leads to wrinkles, and where, if anywhere, gum fits into the big picture.

Why Do People Think Chewing Gum Causes Wrinkles?

First, let’s cut through the rumors. Whenever I talk skin care with clients, facial expressions come up. Think squinting lines or furrows from frowning. So, it makes sense people wonder if repeated chewing—a kind of mini workout for your mouth—could create extra lines. 

Here’s the thinking: Chewing gum means you’re using your orbicularis oris (the muscle around your mouth) over and over. Micro-movements might—just might—lead to fine lines, especially in sensitive areas like the upper lip and cheek. People sometimes call these “smile lines” or marionette lines.

There isn’t a gold-standard clinical study that’s found “chewing gum causes wrinkles” in the same way as, say, smoking or sun damage. But there’s a body of dermatology research showing repeated movement can etch lines into the skin over the years. Just like smiling or frowning every single day might eventually leave a visible trace.

Which Areas Are At Risk When It Comes to Chewing Gum?

Let’s get more specific. If you’re chewing a lot of gum daily, the areas at highest risk are:

• Nasolabial folds: These are the smile lines that run from your nose to the corners of your mouth.

• Marionette lines: Lines that run from the corners of your mouth down toward your chin.

• Upper lip: Fine, vertical lines can develop here from motion and loss of skin elasticity.

• Jawline: Excessive movement can sometimes tighten or change the appearance of jaw muscles, though this is more of a muscle hypertrophy than a wrinkle concern.

If you already have thin, dry, or mature skin, the repetitive motion might show up sooner. The skin around the mouth is naturally thinner and more fragile. If you’re chewing gum for hours every day, this motion can (in theory) accelerate the appearance of lines compared to someone who chews less often.

What Actually Causes Wrinkles?

Here’s where I like to get real with my clients. Wrinkles are part of life. The main factors causing them are:

• Aging: Collagen and elastin—the “scaffolding” proteins in your skin—naturally break down as we get older.

• Sun exposure: UV rays rapidly speed up collagen loss. Sun damage is the #1 cause of premature wrinkles.

• Smoking: Nicotine ages the skin, shrinks blood vessels, and reduces elasticity.

• Genetics: Some folks develop lines and wrinkles earlier due to their DNA—no matter what they do.

• Dry skin: Lacking moisture means skin is less plump and flexible.

• Repeated movement: Smiling, chewing, and frowning all play a minor role, but movement is not the main driver unless it’s extreme.

So, is chewing gum as bad as tanning? Not even close. Compare the damage of a pack of gum a day to a pack of cigarettes a day, and gum barely registers. For a full breakdown of causes, check: Harvard Health - What causes wrinkles?

Does the Type of Gum Matter?

I get this question a lot. Sugar, flavor, shape—do these things impact wrinkles? Here’s what I know from my deep dive into both gum science and consumer feedback.

• Sugar-free gum: This type is actually better for your teeth and overall oral health, which might keep your smile looking younger for longer. (ADA Recommendations)

• Hard, tough gum: Gums that require more forceful chewing might put more strain on the muscles around your mouth. But moderation remains the key—occasional harder chewing won’t do major harm.

• Long-lasting gum: If you’re chewing for hours at a stretch, regardless of type, that’s a lot of movement each day. Take breaks to give your facial muscles a rest.

In my experience, the real danger of gum is jaw fatigue and temporomandibular joint discomfort—not premature wrinkles. But if your goal is skin care, it doesn’t hurt to be intentional about your habits.

Should You Stop Chewing Gum for Smoother Skin?

Honestly? Probably not. The risk of developing more wrinkles from gum chewing alone is low, especially if you’re practicing basic skin care like moisturizing and using SPF. If you’re really chewing nonstop—let’s say hours on end every day—cutting back could make sense. But for most people, the benefits of fresh breath and keeping teeth clean outweigh the minor downside.

If you still worry, I recommend this approach:

• Set a limit: Chew your gum in short bursts (five or ten minutes at a time).

• Switch sides: Avoid overworking one side of the jaw.

• Stay hydrated: Use a lip balm and drink water to keep the skin around your mouth healthy.

• Use SPF daily: Sun damage causes far more wrinkles—this is my #1 anti-aging tip for everyone.

Should You Be Worried About Other Habits, Too?

It’s not just gum—the principle applies to any habit that moves the mouth or face repeatedly. Drinking through a straw all day, whistling, even blowing up balloons—these can all contribute, to a tiny extent, to lines around the mouth.The big difference is frequency and duration. Gum chewing is just one of many repeated habits—but not one of the top offenders.

What’s The Best Way To Keep Your Skin Youthful?

From an expert and daily gum chewer, my best skin advice goes beyond what you put in your mouth:

• Moisturize: Hydrating your skin daily minimizes fine lines.

• Wear sunscreen: Every day. Indoors and outdoors.

• Eat well: A diet rich in antioxidants and healthy fat supports collagen.

• Don’t smoke: This is the fastest path to aged skin.

• Balance your habits: Enjoy your gum, but don’t overdo it.

If you want a more radiant complexion, focus on lifestyle changes with the biggest payoff. In my practice, people who switch to good sun care and stop smoking see more improvement than anyone who gives up gum.

When to See a Dermatologist

If you’re still worried about lines or notice new changes in your skin, seeing a skincare pro is always smart. Dermatologists can recommend noninvasive treatments or products that support collagen and smooth texture.

Conclusion

Chewing gum in moderation is not a major cause of wrinkles. Protect your skin with sunscreen, moisturize daily, and relax—you can enjoy gum without fear of looking older before your time.
