Why is it harder to smile as you get older?

As we age, changes in our facial muscles, skin, and brain function can make smiling more difficult. Some quick answers to why smiling may become harder include:

  • Facial muscles lose elasticity and tone over time
  • Less collagen and fat in facial skin causes wrinkles and sagging
  • Facial nerve function declines, slowing facial movements
  • Changes in brain chemistry and cognition affect emotions
  • Medical conditions like stroke or Parkinson’s disease impair facial expressions
  • Dentures and tooth loss alter the mouth’s structure
  • Mental health issues such as depression are more common in older adults

While aging presents physical challenges to smiling, there are steps people can take to smile more easily. Smiling remains an important part of communication and well-being as we get older.

Changes in Facial Muscles

One reason it may become harder to smile with age is that the facial muscles lose elasticity and tone over time. The main muscles involved in smiling are:

  • Zygomaticus major – Pulls up the corners of the mouth
  • Orbicularis oculi – Forms crow’s feet wrinkles at the eyes
  • Risorius – Pulls the corners of the mouth outward

As we get older, these muscles go through atrophy, shrinking in size and losing strength. The elasticity of muscle tissue decreases as well. This reduces the muscles’ ability to contract and move as dynamically for facial expressions like smiling.

In one study, researchers compared the facial muscle thickness of adults in their 20s versus adults aged 60 and over. They found up to a 30% decrease in muscle thickness in the older group across all facial muscles measured. The zygomaticus major showed some of the greatest muscle loss.

The muscles become weaker with age due to declining levels of hormones, reduced nerve input, changes in metabolism, inactivity, and muscle fiber deterioration. Older muscles have fewer capillaries, mitochondria, and aerobic enzymes as well.

While exercise can help maintain facial muscle tone to some degree, it’s difficult to entirely prevent age-related changes. Diminished elasticity contributes to a more tired, flattened, or tight smile in later life.

Loss of Facial Fat and Collagen

Another age-related change is the loss of facial fat, or subcutaneous fat. This fat pads out the cheeks, chin, lips, and areas surrounding muscles. Facial fat begins decreasing as early as the mid-20s. Aging also leads to bone resorption in the jaws, exacerbating facial fat loss.

With less facial fat, there is less padding for facial expressions. The muscles pull on skin more tightly, making dynamic movements like smiling more challenging. Loss of fat volume especially affects the cheeks, which get hollow and flattened.

Skin also loses collagen and elastic fibers with age. Collagen provides structure within the skin, while elastin allows flexibility. As these decline, skin becomes thinner and looser. Smiling causes creases around the mouth and eyes to deepen into wrinkles and folds. Older skin is less able to snap back into place after making facial expressions.

Aging skin combined with diminished facial fat causes the face to appear more angular and sunken. Smiles may seem narrower as the cheeks lose their fullness. Deep wrinkles can make the mouth appear turned down instead of upturned.

Decline in Facial Nerve Function

The facial nerves control the muscles of facial expression. With age, the functioning of these nerves slows down. Nerve impulses travel more slowly to the facial muscles, leading to delayed reactions and slower movements.

Reduced nerve conduction velocity makes it take longer to form a smile or other expression. Older people may have more difficulty smiling on command, such as for a photograph. Their reactions to amusing stimuli are also slower.

Facial nerve degeneration leads to gradual muscle weakening as fewer nerves activate the muscles. This impairs the ability to fully engage the facial muscles needed to smile. Weakened nerve signals also contribute to facial drooping.

Nerve dysfunction is one cause of facial paralysis conditions like Bell’s palsy. This causes one side of the face to droop, making smiling difficult. Strokes can also damage the facial nerve pathways and muscles impaired by aging.

Changes in Brain Chemistry and Cognition

Aging brings changes in brain structure and function that can affect our emotions and cognition. The brain’s ability to produce key neurotransmitters like dopamine and serotonin declines. These chemicals regulate mood and emotional responses.

Older adults often experience decreased dopamine levels. Since dopamine promotes pleasure and rewards, this reduces enjoyment and motivation. With less dopamine stimulation, it may be harder for the brain to generate positive emotions needed to smile.

Altered cognition in aging can dampen smiling as well. Declines in memory, information processing speed, and executive functioning make it harder to quickly process joyful stimuli. An older brain has trouble shifting focus or adapting to new situations that warrant smiling.

Depression becomes more prevalent with age, likely due to social isolation, medical burdens, loss of loved ones, and other factors. Depressed individuals smile less frequently. Sadness outweighs positive emotions, making smiling difficult.

However, while an aging brain works less efficiently, key areas for emotions like the amygdala maintain their function. Seniors can still experience happiness and smile through positive social interactions, humor, reminiscing, music, pets, hobbies, and other mood boosters.

Medical Conditions Affecting Smiling

Many medical conditions become more common with age and interfere with smiling ability. Neurodegenerative diseases like Parkinson’s, Alzheimer’s, and Huntington’s damage the brain’s motor control centers. This impairs coordination of the facial muscles.

Parkinson’s in particular causes hypomimia – reduced facial expressiveness. Rigidity and tremors make flexing the facial muscles difficult. Individuals with Parkinson’s often have a masked facial appearance.

Stroke can paralyze parts of the face and muscles needed for smiling. Nerve damage from diabetes is another source of facial paralysis. Arthritis in the temporomandibular joints can make mouth movements stiff.

Dental problems like missing teeth, ill-fitting dentures, or jaw joint disorders change the mouth’s anatomy, preventing smiling. Chronic pain conditions also dampen positive emotions needed to smile.

Tooth Loss and Dentures

Tooth loss is nearly universal as people enter old age. Missing teeth affect the facial muscles and mouth structure, which can hamper smiling. The jawbone no longer has the stimulation from tooth roots that maintains its shape and volume.

With missing teeth, the mouth loses structural support. Lips cave inward without teeth to hold the shape. Jaw ridges might protrude without a full set of teeth. Dentures only restore partial facial structure compared to natural teeth.

The mouth may sink when teeth are missing, reducing lip support needed for smiling. Jaw movement can change without a full complement of teeth, altering the mouth’s range of motion. Tongue position changes as well, falling back into the vacant space.

Ill-fitting dentures lead to loose, slipping teeth that make controlled mouth movements difficult. Poorly aligned bite due to missing teeth or dentures prevents the upper and lower lips from joining symmetrically. Partial dentures only replace some missing teeth. All this impairs the proper muscular coordination needed for smiling.

Mental Health Factors

Mental health issues become more prevalent with age and affect smiling capability. Seniors face isolation, loss of loved ones, and physical decline that contribute to depression. Other conditions like anxiety and PTSD are also common.

Depression breeds negative emotions and suppresses urges to smile. The facial muscles might lack the neural drive to engage fully. Chronic pain and fatigue from depression make smiling more challenging. Some antidepressants also cause facial movements to slow.

Anxiety leads to tension in the facial muscles, preventing relaxed, natural smiles. People with PTSD or trauma may unconsciously limit smiling due to hypervigilance. Dementia can impair cognition needed to interact positively with others.

Getting treatment for mental health conditions can help older adults regain interest in socializing and rediscover reasons to smile. Therapies to process grief, relax, stay active, and gain support can relieve negative emotions.

Tips for Smiling More as You Age

While aging makes smiling more difficult, there are steps people can take to smile more easily:

  • Do facial exercises like gently stretching the mouth and lifting the cheeks
  • Massage face muscles to increase blood flow
  • Stay socially engaged and interact with positive people
  • Find activities that bring joy like hobbies, pets, music, and humor
  • Manage stress through relaxation techniques, sufficient sleep, and social support
  • Treat any medical or mental health conditions causing facial impairment
  • Consider cosmetic treatments like Botox, fillers, facelifts, or dentures
  • Practice smiling regularly even if it feels unnatural at first

Smiling remains important for communication, relationships, and well-being as we age. With some adaptations and effort, seniors can reap the benefits of smiling despite the challenges of aging.

Facial Exercises

Performing facial exercises can preserve and improve the muscular coordination needed for smiling. Exercises combat muscle and nerve deterioration by:

  • Increasing blood circulation
  • Preserving nerve pathways
  • Maintaining muscle tone and elasticity
  • Strengthening weak facial muscles
  • Improving motor control

Helpful exercises include:

  • Stretching mouth gently with fingers
  • Puffing out cheeks and holding
  • Lifting eyebrows up and down
  • Pursing and relaxing lips
  • Scrunching nose
  • Opening mouth wide and pouting

These exercises can be done daily for 5-10 minutes to keep the muscles conditioned. Moving the face through its full range of motion fights stiffness and trains muscles to make smiles and other expressions.

Facial Massage

Massaging the facial tissue improves blood flow, removes tension, and stimulates the facial nerves. This enhances nerve signaling to muscles to gain strength for smiling. Massage techniques like effleurage, petrissage, and tapotement work:

  • Effleurage – Gliding strokes across skin surface
  • Petrissage – Kneading motion with fingers
  • Tapotement – Quick, percussive taps

Focus massage on the smiling muscles around the mouth, eyes, and cheeks. Massage before doing facial exercises to prime the muscles. Apply a facial oil to reduce friction for easy gliding movements across the skin.

Staying Social

Making an effort to stay socially engaged can provide more opportunities to smile. Interacting with family, friends, and community provides positive stimuli that elicit smiling.

Joining social clubs, volunteering, scheduling visits with loved ones, and taking group classes are ways seniors can stay connected. These activities boost mood through enjoyable interaction and offer reminders about things to smile about.

Surrounding yourself with positive people who smile frequently can be contagious. Their upbeat emotions and reactions may rub off on you. Shared laughs and informal social gatherings can help smile muscles remember how to contract.

Finding Joyful Activities

Engaging in hobbies, interests, and leisure activities you enjoy gives your brain more chances to light up with positive emotions that produce smiles. Here are some rewarding activities to try:

  • Play with pets or grandkids
  • Listen to favorite upbeat music
  • Watch comedy shows or funny videos
  • Read humor books or magazines
  • Reminisce over photo albums or cherished memories
  • Cook or bake favorite recipes
  • Work on arts, crafts, or DIY projects
  • Spend time outdoors in nature

Any activities you find calming, mentally engaging, nostalgic, or amusing can stimulate smiles by improving your mood.

Stress Management

Chronic stress takes a toll on mental and physical health, diminishing capacity for smiling. Relaxation techniques, getting adequate sleep, and finding social support can help keep stress in check.

Meditation, deep breathing, yoga, tai chi, art therapy, and music therapy induce relaxation. Letting go of negative thoughts and anxiety makes room for more positive emotions.

Good sleep allows the brain to recharge and maintain healthy emotional processing. Having an active social network provides resources to better handle life’s stressors. Staying stress-resilient preserves the ability to smile.

Medical and Mental Health Treatment

Seeking treatment for medical conditions or mental health issues causing facial impairment can enable more frequent smiling. Possible options include:

  • Medications, physical therapy, Botox injections for facial paralysis
  • Surgery, amputation, prosthetics for stroke-damaged limbs
  • Dopamine therapy for Parkinson’s smile issues
  • Counseling, antidepressants for depression
  • Cognitive behavioral therapy for anxiety
  • Support groups, memory training for dementia

Taking steps to improve limitations from aging, disease, or trauma can help reanimate the face to smile again.

Cosmetic Treatments

For those concerned about age-related facial changes affecting their smile, there are cosmetic treatments that may help:

  • Botox – Reduces dynamic wrinkles around mouth and eyes
  • Dermal fillers – Plump up facial folds, lips, cheeks
  • Facelift surgery – Tightens sagging facial skin
  • Neck lift – Corrects drooping mouth corners
  • Teeth whitening – Brightens smile appearance
  • Dental implants – Replace missing teeth
  • Dentures – Improve fit for toothless mouths

These treatments may make some smiles appear more vibrant and youthful. However, cosmetic procedures have risks, require upkeep, and can only partially achieve natural facial movement.

Practice Smiling

One of the most effective ways to smile more easily is practicing regularly. Setting aside time each day to perform smiling exercises “retrains” the facial muscles.

Try pulling the mouth upward into a smile for 10 seconds while tightening the cheeks. Smile dynamically by slowly transitioning between a relaxed face and full grin.

Looking at photos of yourself smiling can provide feedback to adjust the mouth and eyes. Smiling into a mirror lets you tweak the expression in real time.

With regular practice, smiling can start to feel more natural, automatic, and effortless. The muscles will rebuild strength and muscle memory.


Aging brings many changes that can make smiling more difficult, from altered facial anatomy to declines in mood. However, smiling remains beneficial for health and social connection. With some diligence through facial exercise, finding joyful activities, managing medical conditions, and practice, older adults can regain the ability to smile frequently.
