The bony and cartilaginous framework of the nose reaches its adult size somewhere in the mid-teens, but the nose itself never truly stops changing. A systematic review of adolescent growth data puts the end of the nasal growth spurt at roughly 13 for girls and 15 for boys, with nearly all adolescents reaching skeletal nasal maturity by about 16 and 17 respectively. Yet measurements of people well into their seventies show that nasal volume, surface area, and most linear dimensions keep increasing across the entire lifespan. The short answer is that growth in the textbook sense wraps up in adolescence, but a different set of processes ensures that your nose at 70 looks meaningfully different from your nose at 30.
When the Growth Spurt Ends
The fastest period of nasal growth tracks closely with the broader puberty-driven growth spurt. A systematic review analyzing nasal growth velocity curves defined the end of the spurt as the point where growth speed drops off most steeply. For girls, that point arrived at an average age of about 13, and for boys around 15. Adding a statistical margin to account for individual variation, the review concluded that 98 percent of white adolescent girls were nasally mature by roughly age 16, and 98 percent of white adolescent boys by about age 17.1JAMA Otolaryngology–Head & Neck Surgery. Nasal Growth and Maturation Age in Adolescents: A Systematic Review
A cephalometric study looking at both bony and cartilaginous components broke this down further. Nasal height and nasal bridge length reached full maturity by about age 15 in boys and 12 in girls. The nasal tip, which is almost entirely cartilage, approached its mature size by 15 in boys and 13 in girls.2PubMed. Adolescent growth patterns of the bony and cartilaginous framework of the nose: a cephalometric study A separate longitudinal study tracking children from age 6 to 18 found that girls reached nasal maturity by age 12, at which point the nose was about 84 percent of its adult area, while boys hit that milestone around 15 with roughly 87 percent of adult size.3Annals of Plastic Surgery. A Longitudinal Study of Nose Growth from Ages 6 to 18
The pattern is consistent across these studies: girls finish sooner than boys, by roughly two to three years, mirroring the earlier onset and completion of puberty in females generally. After the late teens, the skeleton of the nose is done expanding.
Why the Nose Keeps Getting Bigger Anyway
If skeletal growth wraps up by the late teens, why do older adults often look like their noses have gotten longer or wider? A large morphometric study that digitized the external noses of over 850 people aged 4 to 73 found that nasal volume, surface area, and linear distances all continued to increase from childhood into old age. At the same time, the nasal tip angle decreased, meaning the tip droops progressively downward.4PubMed. Age- and sex-related changes in the normal human external nose These changes are not growth in the traditional sense. They are the combined result of cartilage degradation, bone resorption, gravity, and skin thinning, all of which reshape the nose decade by decade.
Cartilage Degradation and the Drooping Tip
Nasal cartilage does not simply sit there unchanged once puberty ends. The cells inside it (chondrocytes) become less active over time, and the structural molecules that keep cartilage firm start to thin out. A study examining nasal cartilage samples from people of various ages found that proteoglycan content, the molecules that help cartilage retain water and resist compression, declined significantly with advancing age.5PubMed. Age-related histologic changes in human nasal cartilage
Follow-up biochemical work has fleshed out the picture. One study documented a significant decline in glycosaminoglycans (the sugar molecules that make up proteoglycans) in nasal cartilage with age, alongside an increase in collagen content and a drop in cell count across all cartilage subsites examined.6PubMed. Age-Related Histologic and Biochemical Changes in Auricular and Nasal Cartilages Another analysis of septal cartilage put a number on the glycosaminoglycan loss: about 2.4 percent per year, with cell density and cell size also declining over time.7PubMed. Age-related histologic and biochemical changes in auricular and septal cartilage
The practical effect of all this is that nasal cartilage gradually becomes stiffer and less resilient but also weaker as a structural support. The lower lateral cartilages, which give the nasal tip its shape and projection, lose their ability to hold the tip upward. Gravity does the rest. Over decades, the tip drops, the nose appears longer, and the angle between the upper lip and the columella (the strip of tissue between the nostrils) gets more acute. People often describe this as the nose “growing,” but it is really a slow structural collapse.
The Skull Shrinks Underneath
While cartilage weakens from the inside, the bony foundation underneath the nose is also remodeling. The piriform aperture, the pear-shaped bony opening in the skull through which the nasal cavity exits, actually enlarges with age as the edges of the surrounding bone recede. Bone loss is not even across the opening; it is greatest at the bottom, right where the bone supports the base of the nostrils. This preferential bone loss in the lower part of the piriform aperture leads to a posterior displacement of the alar base, making the nostrils appear to settle backward and the nose to look less supported.8PubMed Central. Changes in the Facial Skeleton With Aging: Implications and Clinical Applications in Facial Rejuvenation
A CT-based study confirmed that the pyriform aperture area increased significantly with age in both men and women, and that the angles of the glabella and midface decreased, reflecting broader resorption of the midface skeleton.9Plastic and Reconstructive Surgery. Aging of the Facial Skeleton: Aesthetic Implications and Rejuvenation Strategies The bone loss also contributes to deepening of the nasolabial fold, something previously blamed entirely on sagging soft tissue. In reality, the underlying scaffolding is receding, and everything sitting on top of it sinks with it.
Skin and Soft Tissue Add to the Illusion
The skin covering the nose changes too. With age, the dermis thins and loses collagen and elastin, the fibers that keep skin taut and elastic. Subcutaneous fat decreases on the face, and sebaceous glands, though they tend to enlarge, produce less oil. The net result is thinner, looser skin draping over weakened cartilage and retreating bone.10PubMed. Structural and functional changes of normal aging skin When you lose padding between the skin and the cartilage, every bump and asymmetry in the underlying framework becomes more visible. People who had a very subtle dorsal hump at 25 may find it much more prominent at 65, not because the cartilage grew but because the camouflage is gone.
Gravity compounds things. Thinner skin with less elastic recoil stretches more readily under its own weight. The tip skin, which is thicker than the dorsal skin in many people, can become heavy enough to pull the tip further downward. This is partly why the nose appears to lengthen more dramatically in some people than others: it depends on the starting thickness of the skin envelope and how much collagen it retains over time.
Sex Differences in How the Nose Ages
Men’s noses tend to be larger than women’s at every stage of life, but the processes of growth and aging follow similar trajectories in both sexes. One study comparing nasal septal growth between males and females found that while the final dimensions were significantly larger in males, the growth process itself was not remarkably different between the sexes.11PubMed. Are gender differences in external noses caused by differences in nasal septal growth?
Where differences show up more clearly is in the age-related changes of adulthood. Nasal height increases significantly with age in both sexes, but the magnitude of change and the pattern of when changes accelerate can differ. One cross-sectional study of nasal parameters across age groups found that nasal height and nasal breadth increased with age in both men and women, that the nasolabial angle decreased with age in both, and that on most measures male values were higher than female ones.12PubMed Central. Nasal changes in different age groups The large morphometric study of 859 subjects also reported significant sex-by-age interactions, meaning men and women did not age in perfectly parallel tracks. Men had larger nasal volume and area as well as a greater nasal width-to-height ratio on average, though the angles of the nose and the ratio of tip protrusion to nasal height showed no sex difference.4PubMed. Age- and sex-related changes in the normal human external nose
A reasonable takeaway is that men tend to start with bigger noses and likely experience more absolute change over time, but women are not exempt from the same drooping and widening processes. The hormonal differences that drive earlier skeletal maturity in women do not protect them from the cartilage and bone changes of later life.
What This Means for Breathing
Nasal aging is not purely a cosmetic story. The same structural changes that make the nose look different can alter airflow. A study of adults across age groups identified a pattern of increasing nasal airflow resistance with age, along with a higher likelihood of certain nasal complaints.13PubMed. Aging of the normal nose in adults An investigation focusing specifically on elderly patients found that the nasal cavities were significantly larger in older subjects, which sounds like it should make breathing easier. But the enlarged cavities came from atrophy of the nasal mucosa, the moist lining inside the nose, which meant the air passing through was less effectively warmed and humidified. The result was drier, cooler airflow reaching the throat and lungs, and a corresponding increase in nasal complaints like dryness and crusting.14PubMed. Age-related changes in intranasal air conditioning in the elderly
The weakening of lateral nasal wall cartilage also plays a role. When the lower lateral cartilages can no longer hold the sidewalls of the nose open during a strong inhale, the walls can collapse inward, restricting airflow. Older adults who notice that breathing through the nose feels harder, especially during exercise, may be experiencing this valve insufficiency rather than congestion. The fix is sometimes as simple as a nasal dilator strip, though surgical reinforcement of the cartilage is an option for more severe cases.
The Ears Comparison
Noses and ears are often mentioned in the same breath because both are cartilaginous structures that appear to keep growing throughout life. A cross-sectional study comparing ear and nose measurements in young and old individuals found that both structures were larger in older people, but ear dimensions actually correlated more strongly with age than nasal dimensions did, with the exception of the ear tragus.15PubMed. Ear size as a predictor of chronological age The popular claim that “your nose and ears never stop growing” is a simplification. Neither structure is actively growing new tissue the way a child’s skeleton does. Both are passively changing shape because their cartilage degrades and gravity pulls on the softened framework. Ears just happen to show this effect more strikingly, in part because the ear has a larger, flatter cartilage plate that deforms more readily under its own weight.
Why Surgical Timing Matters
The adolescent growth data has direct implications for anyone considering rhinoplasty. Operating on a nose that has not finished growing risks an unpredictable result, because the remaining growth could distort whatever shape the surgeon created. The common clinical guideline is to wait until the nasal skeleton has reached maturity, generally interpreted as around age 15 to 16 for girls and 17 to 18 for boys. The systematic review’s finding that 98 percent of girls are nasally mature by about 16 and 98 percent of boys by about 17 is the evidence underpinning that guideline.1JAMA Otolaryngology–Head & Neck Surgery. Nasal Growth and Maturation Age in Adolescents: A Systematic Review In practice, surgeons also evaluate individual skeletal maturity through other cues, like whether the patient has reached their full adult height, because nasal growth and overall skeletal growth track together.
What surgeons cannot account for is the decades of post-growth change. A rhinoplasty performed at age 20 will look different at age 60 because of the cartilage, bone, and skin changes described above. This is one reason revision rhinoplasty becomes more common later in life, and why some surgeons advise building in a small amount of structural overcorrection to compensate for predicted tip drooping. Understanding that the nose will keep changing shape long after it stops growing is relevant for anyone weighing the decision.
How Climate Shaped the Nose You Start With
Before aging reshapes the nose, genetics and ancestral climate have already determined its baseline proportions. Nostril width correlates significantly with both temperature and humidity of the climate where a population evolved. People from warm, humid environments tend to have wider nostrils, while those from cool, dry climates tend to have narrower ones.16PubMed Central. Investigating the case of human nose shape and climate adaptation A study of nasal cavity shape across populations found that the internal architecture also varies with climate: people from cold, dry regions tend to have nasal passages with a higher surface-to-volume ratio, which helps warm and humidify cold air more efficiently before it reaches the lungs.17PubMed. Climate-related variation of the human nasal cavity
A systematic review of nasal index measurements across ethnic groups confirmed that proportions vary between populations but cautioned that nose shape does not neatly define racial categories. The variation is better understood as a continuum of adaptation to different environments.18PubMed. A systematic review of the nasal index and the significance of the shape and size of the nose in rhinology These inherited proportions determine the starting point from which all the age-related changes proceed. Someone who inherits a wider alar base may experience different aesthetic aging than someone with a naturally narrow nose, even though the underlying cartilage and bone processes are similar.
Perceptions of Nose Size and Attractiveness
Given that the nose gradually lengthens and widens with age, it is not surprising that smaller nose proportions are generally rated as more youthful-looking. A survey on facial attractiveness found that about 65 percent of respondents preferred slightly reduced nose proportions in women, with a reduction to 90 or 95 percent of original size rated as more attractive. The preferred nose size was significantly smaller for female faces than for male faces.19PubMed. Impact of face proportions on face attractiveness Whether this preference reflects an unconscious association between a smaller nose and youth, or is culturally conditioned, remains debated. But the finding lines up with the biological reality: a nose that has not yet been reshaped by decades of cartilage loss and tip drooping will, on average, appear smaller and more projected.
This also helps explain why non-surgical nose treatments, such as filler injections to smooth humps or lift a drooping tip, have become increasingly popular among middle-aged adults. These procedures do not change the size of the nose. They add volume in strategic spots to counteract the visual effects of structural loss, essentially mimicking what the nose looked like before aging took hold. The demand reflects a growing awareness that the nose keeps changing long after it finishes growing, and that many of those changes are driven by loss of support rather than by gain of tissue.
