Understanding the dynamics of adult facial change
The period of rapid facial bone growth largely concludes by the late teenage years. However, this does not mean that facial structure becomes entirely fixed. Throughout adulthood, the face continues to undergo changes, albeit at a slower and more subtle pace than during the intense growth phase of adolescence. This ongoing transformation is a complex interplay of biological processes, genetic predispositions, and external influences that shape the face over a lifetime.
The continuous process of bone remodeling
Bone is a dynamic tissue that is constantly being broken down and rebuilt through a process called remodeling. This occurs throughout the entire skeleton, including the bones of the face. While the net increase in size seen during adolescence ceases, the subtle reshaping of facial bones continues [1]. This remodeling can lead to gradual alterations in the contours and proportions of the face over time.
Specific areas of the adult face are more susceptible to these changes:
- Midface and Orbital Area: Studies indicate that the bones surrounding the eyes (orbits) tend to enlarge with age due to bone resorption. The midface, including the maxilla (upper jaw), can also experience a degree of bone loss, which can affect its projection and contribute to changes in facial shape [1].
- Mandible and Jawline: Although the size of the mandible (lower jaw) generally stabilizes, remodeling continues. The angle of the jaw may become wider, and bone density can be affected by factors like tooth loss [2]. Some research suggests minimal ongoing growth in certain facial areas like the jaw, nose, and ears throughout life [3].
- Nasal Bones: The bony structure supporting the nose also undergoes changes, including enlargement of the piriform aperture (the nasal opening in the skull), which can subtly alter the appearance of the nose over time [1].
Soft tissue's significant role in adult facial aesthetics
The overall appearance of your face is not solely determined by bone structure. The overlying soft tissues – skin, fat, muscle, and ligaments – also play a crucial role and undergo significant changes in adulthood. These soft tissue changes often become more noticeable than the subtle shifts in the underlying bone.
- Fat Redistribution and Loss: The subcutaneous fat pads that give the face a youthful fullness change with age. They can lose volume and descend due to gravity and the natural aging process. This shift contributes to the formation of jowls, deepening of nasolabial folds (lines from the nose to the mouth), and hollowing under the eyes [4].
- Collagen and Elastin Degradation: The skin's structural integrity relies heavily on collagen and elastin fibers. As individuals age, the production of these proteins decreases, and existing fibers degrade. This leads to reduced skin elasticity, increased laxity, and the formation of wrinkles and sagging [5].
- Muscle and Ligament Changes: Over time, repetitive facial muscle movements contribute to expression lines. Changes in facial ligaments, which help support the facial tissues, can also reduce their ability to counteract gravity, further contributing to sagging [6].
Environmental and lifestyle factors influencing adult facial aging
While genetics provide a blueprint, a variety of external factors significantly impact how your facial structure and appearance evolve after age 17. These influences can accelerate or mitigate the visible signs of aging.
- Oral Health and Dental Care: The presence and health of your teeth are intrinsically linked to jawbone structure. Tooth loss can lead to bone resorption in the jaw, altering the shape of the lower face and chin. Regular dental checkups and addressing issues like tooth loss or malocclusion (improper bite) are vital for maintaining facial structure [2]. Orthodontic treatments in adulthood can also impact jaw alignment and facial symmetry [7].
- Diet and Nutrition: A balanced diet rich in calcium, vitamin D, and other essential nutrients is crucial for maintaining bone density and overall health, which in turn supports facial structure. Adequate hydration also contributes to skin health and elasticity [8].
- Sun Exposure: Chronic exposure to ultraviolet (UV) radiation from the sun is a primary cause of premature skin aging, known as photoaging. UV rays break down collagen and elastin, accelerating wrinkle formation and sagging [5]. Protecting your skin with sunscreen is essential for preserving its structure and appearance.
- Smoking: Smoking is highly detrimental to skin health. It reduces blood flow, impairs collagen production, and accelerates the breakdown of elastic fibers, leading to increased wrinkles, sallowness, and a generally aged appearance [5].
- Posture: Poor posture, particularly forward head posture often associated with using electronic devices, can affect the alignment of the jaw and neck, potentially influencing the contours of the lower face over time.
Factors Influencing Post-17 Facial Changes: Genetics vs. Lifestyle
| Factor | Influence on Facial Change | Examples |
|---|---|---|
| Genetics | Predisposition to certain facial shapes, bone density, and aging patterns | Inherited bone structure, tendency for wrinkles, fat distribution |
| Lifestyle | Modifies genetic predispositions and influences the rate of change | Diet, exercise, sun exposure, smoking, oral care, sleep |
| Environment | External factors impacting the face | UV radiation, pollution, climate |
| Health Status | Underlying health conditions can affect facial tissues | Bone density issues, hormonal changes |
| Habits | Repetitive actions influencing facial muscles and skin | Smiling, frowning, chewing habits, resting position |
Promoting healthy facial aging
While the natural progression of aging is inevitable, several strategies can help support healthy facial structure and appearance after 17. Focusing on overall health and protecting the skin are key components.
- Prioritize Oral Health: Maintain excellent dental hygiene, attend regular checkups, and address any tooth loss promptly to preserve jawbone structure [2]. Consider orthodontic consultations if needed [7].
- Protect Your Skin from the Sun: Consistent use of broad-spectrum sunscreen is the most effective way to prevent photoaging and maintain skin elasticity [5]. Wear hats and seek shade during peak sun hours.
- Adopt a Nutrient-Rich Diet: Ensure adequate intake of vitamins, minerals, and protein to support bone health and skin vitality [8]. Stay hydrated by drinking plenty of water.
- Avoid Smoking: Quitting smoking or never starting is one of the most impactful steps you can take for your skin and overall health [5].
- Manage Stress and Get Sufficient Sleep: Chronic stress and lack of sleep can negatively impact skin health and accelerate visible signs of aging.
- Maintain a Healthy Weight: Significant fluctuations in weight can affect facial fat volume and skin elasticity.
- Consider Professional Skincare: Consult with dermatologists or skincare professionals for personalized advice and treatments to address specific aging concerns.

Conclusion: A face in perpetual, subtle evolution
To answer the question, "will my facial structure change after 17?", the clear answer is yes. The notion that facial development completely halts after the teenage years is a simplification. While the rapid, dramatic growth phase concludes, the face continues to evolve throughout adulthood. This ongoing change is driven by the continuous process of bone remodeling, alterations in soft tissue like fat pads and skin elasticity, and a significant influence from lifestyle choices and environmental exposures. Understanding these dynamics highlights that your face is a living, changing entity. By adopting healthy habits and protecting your skin and bone health, you can positively influence how your face ages and continues to change in subtle ways over the years.
