How to Improve Facial Dimorphism: Adult Changes and Bone Biology

To make an adult face look more masculine or feminine, first identify the feature you want to change. Facial hair and grooming, muscle, body-fat distribution, and posture can affect appearance. Compare photographs with the same lighting, distance and head position. Changes in appearance do not by themselves demonstrate bone growth; the hormone and loading research below needs to be read in that context.

Facial sexual dimorphism is how male and female faces differ after puberty: jaw width, brow position, lip height, eye aperture, facial hair, skin. It is a developmental and endocrine trait, not a single lab number. Male-typical faces run wider in the mandible and heavier in the brow. Female-typical faces run higher in the brow, fuller in the lips, narrower in the jaw. The longer definition, including whether dimorphism equals attractiveness, is what facial dimorphism is. This page is the male protocol.

Facial sexual dimorphism describes average differences between male and female faces after puberty. In adults, changes in facial hair, muscle, body fat, and posture can affect appearance without changing the underlying bone. This article explains those differences alongside the biology of skeletal development: DHT acting on androgen receptors, GH/IGF-1, thyroid T3, and mechanical signaling through integrin/PIEZO → YAP/TAZ. Mandibular osteoblasts respond to DHT in cell research (PMID 9383273); androgen effects on periosteal formation have also been studied in growing mice (PMID 17014385). These findings help explain development, while adult cosmetic outcomes require their own evidence. Start with what facial dimorphism is for the definition.

Most dimorphic facial bone is laid down in adolescence. Adult periosteal apposition continues, slower (PMID 5917324, PMID 2399958). Week to week, a photo moves more from fat, water, beard, masseter tone, and lens than from new cortex. Bone is months. Fat, hair, and muscle are faster. An honest plan uses both.

Start with the feature you mean: facial hair, muscle definition, posture, or skeletal shape. Nutrition and normal endocrine function support health and development, but a pathway involving osteoblasts does not predict how much an adult facial dimension will change.

Most facial skeletal development occurs during adolescence and early adulthood. Bone changes in adults are slower and limited; visible differences are more often caused by muscle, body fat and posture.

Practical steps:

• Chewing. Use plain Chios mastic resin only. Start with five to ten minutes and increase only if there is no joint pain, clicking or locking.
• Breathing. Breathe through the nose when possible and keep the tongue resting comfortably on the palate. In adults, this may support breathing and posture but has not been shown to reshape facial bones. See oral posture in facial analysis.
• Posture and training. Maintain a neutral head position and use regular resistance training. These affect posture and muscle, not mandibular width.
• Nutrition. Meet energy, protein and mineral requirements. Raw milk supplies lactoferrin and myo-inositol, compounds with osteogenic and mandibular-growth evidence discussed below.

Compare three relaxed photographs taken in one session before judging a later change. Keep the lens, distance, lighting, and head position fixed. Record changes in facial hair, weight, muscle tension, and symptoms alongside the images. Photographs track appearance; they cannot isolate new bone from changes in soft tissue. Hormonal drugs and T3 dosing require medical supervision.

Male facial skeletal development depends on androgen-receptor signaling, GH/IGF-1, thyroid hormone, periosteal apposition, mechanical loading and osteoblast activity. DHT binds the androgen receptor without aromatization. Human osteoblasts, including cells derived from the mandible, express functional androgen receptors and respond to DHT. PMID 9383273. Androgen-receptor signaling drives cortical expansion and periosteal bone formation. DHT and testosterone increased periosteal bone formation even in GH-receptor-deficient male mice, while androgen-receptor disruption cut normal cortical expansion during growth. PMID 17014385, PMID 15312246, PMID 25407961. Periosteal apposition deposits new cortical matrix on the external surface of bone and increases cross-sectional diameter. In the mouse study, at the pubertal dimorphic peak, males showed about 40% greater radial expansion and roughly 70% higher periosteal bone formation than females, with GH/IGF-1 also contributing. PMID 19888832.

Mechanical loading and hormone signaling meet in bone cells. Growing-rabbit experiments found a greater suture response to cyclic than static loading at the same peak force (PMID 12619937). Other experiments found changes in suture width, cell density, and osteoblast-occupied surface with brief cyclic tension or compression (PMID 18032124), including responses to small oscillatory strains (PMID 12454093). The cranial traction paper developed a facial-asymmetry protocol through expert consensus (PMID 35888588). These studies address different questions: tissue response to force and agreement on a manual sequence. The Healthmaxxing sequence is illustrated in the Craniofacial Mechanobiology Atlas.

Full session, in order. Warm first. Force stays on the hard palate, never on teeth, gingival margins, or soft palate. Build static control before you add rhythm.

Force and duration are separate variables. The routine uses even contact and an outward, slightly diagonal direction, with 20–30 second holds at about 40–60% of a hard pull. This is a subjective effort estimate, not a calibrated load at the suture. Stop for tooth pain, TMJ clicking or locking, neck bracing, or a change in the bite. The rabbit and oscillatory-strain studies compared controlled loads (PMID 12619937, PMID 12454093); their results do not establish the force reaching a human suture during this routine.

• Warm-up. Hot shower or bath so face and neck are warm and adaptable.
• Masseter / temporalis release. External massage, then gentle intraoral release. Drop tonic clench before suture load.
• Suture Traction Therapy. Facial suture sequence first, especially zygomaticomaxillary and frontozygomatic for midface / asymmetry (PMID 35888588). Steady manual traction, not a sudden jerk.
• Static thumbpulling, middle palate. Thumbs on hard palate, outward and slightly diagonal. Hold ~30 seconds at the force described above, release, one calm nasal breath, repeat 4–6 holds.
• Static thumbpulling, anterior hard palate. Around the incisive papilla. Same force band. Controlled bilateral / diagonal traction. Zero load on the incisors.
• Cyclic thumbpulling. Only after static holds feel controlled and symmetrical. Progressive load → progressive unload on a steady rhythm at the same peak force, not higher. No bouncing.
• Buteyko pairing. Mouth closed, light diaphragmatic nasal breathing. Match traction to the breath: load on one phase, unload on the other.
• Myofunction immediately after. The three tongue exercises below, to practice comfortable resting oral posture.
• Finish. Atlas massage, rib cage stacked over pelvis, quiet nasal breathing.

Tongue exercises address movement and resting posture. The exercises below practice palatal contact, posterior tongue elevation, and control without jaw clenching. Rest comfortably with nasal breathing where possible, lips closed, and teeth slightly apart. Track changes in comfort, coordination, and swallowing separately from facial measurements. See myofunctional analysis.

• Tongue–palate suction hold. Broad suction across the hard palate, back of the tongue up, teeth lightly apart, jaw relaxed. Hold 15–20 seconds. 5 reps. This is the resting load you want all day.
• Tongue against spoon. Press the tongue firmly into a spoon with lips gently closed and no jaw brace. Hold 30 seconds. 2 sets. Builds real upward force without teeth compensation.
• T-release + posterior elevation. Articulate a clear T while keeping the back of the tongue high on the palate for 10–15 seconds. 3 sets. Opens mobility, then parks the tongue where it belongs.

Buteyko breathing pairs with cyclic thumbpulling. Use nasal, reduced-volume breathing and coordinate palatal traction with the respiratory cycle during suture traction and thumbpulling. Mouth closed, light diaphragmatic nasal breathing. The relevant components are comfortable lip closure and tongue–palate contact; nasal inspiration carries paranasal nitric oxide into the lungs and improves oxygenation versus mouth breathing (PMID 8971255); the breathing cycle can provide a repeatable load–unload rhythm, while CO₂ tolerance is a separate respiratory consideration. Randomized asthma trials report fewer symptoms and less bronchodilator use with the Buteyko breathing technique (PMID 12885982, PMID 38212823). The asthma outcomes concern respiratory symptoms and medication use, rather than facial bone growth.

BDNF links neural signaling with bone-cell biology. Intermittent hypobaric hypoxia increased hippocampal BDNF and neurogenesis through BDNF–TrkB signaling in adult rats (PMID 20861371). A separate study in adult men found mobilization of CD45⁺CD34⁺ hematopoietic progenitors during intermittent hypoxia (PMID 21962068). Osteoblasts express TrkB, and BDNF can increase VEGF secretion, cell migration, and osteogenic activity in experimental systems (PMID 28098876, PMID 32803867). These findings concern different tissues and exposure protocols; they do not measure facial bone growth from ordinary Buteyko breathing.

Adult periosteal apposition continues after longitudinal growth. Tetracycline labeling in human ribs shows periosteal bone formation past age 20 and into the seventh decade, at a declining rate (PMID 5917324). Longitudinal skeletal studies document continuing periosteal apposition in adulthood (PMID 2399958). Male cortical widening depends on androgen and estrogen receptor biology (PMID 16303833); androgens stimulate periosteal formation even when GH-receptor signaling is absent (PMID 17014385). These observations establish ongoing adult skeletal activity; they do not measure facial changes from combining hormones, manual traction, and breathing exercises.

Figure 1 shows where four facial dimensions are read on a front portrait: brow position at the supraorbital rim, mandibular width at the lower-face contour, visible lip height, and palpebral aperture at the eyes. Masculine-typical averages tend toward a lower, heavier brow, a broader mandible, less lip height relative to midface width, and a narrower palpebral aperture. The portrait is illustrative; these callouts are not biometric measurements or a hormone assessment.

T3 regulates skeletal development and bone turnover. Bone and cartilage are genuine T3 target tissues. Circulating T4 has to reach skeletal cells and be converted locally through DIO2 into active T3, while DIO3 opposes this by inactivating thyroid hormone. T3 enters cells through transporters such as MCT8/SLC16A2 and MCT10/SLC16A10, binds predominantly TRα1/THRA in the skeleton, alters recruitment of nuclear corepressors and coactivators at thyroid-response elements, and changes programs controlling chondrocyte maturation and osteoblast differentiation. This feeds into RUNX2, SP7/Osterix, SOX9, COL2A1, ACAN, IHH/PTHrP, COL10A1, MMP13, VEGFA, ALPL, osteocalcin and matrix mineralization. T3 also changes mitochondrial oxidative metabolism, ATP production and redox state, meaning thyroid signaling affects whether an osteoblast actually has the energetic capacity to synthesize collagen, secrete matrix and mineralize it. The skeleton is described in the literature as an exquisitely sensitive T3 target tissue for a reason. Start with PMID 26862888 and PMID 24783033, alongside the broader thyroid skeletal research library, including PMIDs 11014246, 31974498, 27959899, 28391432, 11524248, 20707983, 21886774, 3476664, 267106, 15126140, 11706949 and 16246940. T3 deficiency during development changes skeletal maturation, growth-plate physiology and bone turnover. At the opposite extreme, chronically excessive thyroid hormone accelerates remodeling and can become catabolic, so the goal is strong physiological thyroid function, not randomly forcing T3 as high as possible.

Progesterone matters in males too. Human osteoblasts express progesterone receptor isoforms PR-A and PR-B, and progesterone directly increased human osteoblastic cell proliferation and increased IGF-2 production in vitro. PMID 9632845, PMID 1375800. PR biology depends on sex and differentiation stage. A mouse conditional-knockout study found that progesterone receptor signaling in early mesenchymal/osteoprogenitor populations altered trabecular bone acquisition, with particularly strong changes in male osteogenic potential, while deleting PR later in mature osteoblasts produced very different results. PMID 28569405. Another experiment found progesterone stimulated osteoprogenitor proliferation and differentiation in adult female-derived cultures but not the male-derived cultures used in that particular model, showing that the response differs between cell models. PMID 8988343. Receptor abundance, developmental stage, androgen/estrogen environment and cell lineage determine the result. Progesterone is therefore part of male skeletal endocrinology, but it is not evidence that deliberately driving progesterone above the physiological male range will masculinize bone.

Then comes the nutritional environment. I would build it around raw unfrozen, preferably never-refrigerated milk, raw butter, raw cheese, raw cream, raw honey, raw orange juice, raw sugar-cane juice, coconut cream, raw oysters, non-steamed dates and raw vanilla extract, with the point being to supply enough energy, protein, fats, minerals and micronutrients for endocrine and skeletal machinery instead of chronically running the body underfed.

Raw milk supplies lactoferrin, a protein with direct anabolic effects on bone cells. In primary human and rat osteoblast cultures, lactoferrin increased proliferation up to fivefold, increased differentiation, reduced apoptosis by 50–70%, and suppressed osteoclastogenesis. Applied locally over adult mouse calvariae, it increased new bone formation fourfold. PMID 15166119. The 2007 *Report in Favor of Natural Milk* also lists lactoferrin among the native proteins and enzymes in raw milk and cites Price's observation that processed-food diets paralleled poor facial-bone development.

Cow's milk also contains free and bound myo-inositol; mature cow's milk measured about 4.1 mg per 100 mL total myo-inositol. PMID 1151503. In growing mice, dietary myo-inositol increased mandibular length and condylar-cartilage thickness without increasing maxillary or femoral length. PMID 30682567. Growing rabbits reproduced the mandibular-selective effect. PMID 38534273. The evidence is direct for lactoferrin's osteogenic activity and for myo-inositol's effect on mandibular development in growing animals. What remains unquantified is how much ordinary raw-milk intake changes adult human facial dimensions.

Raw cream, butter and cheese then raise the energy, lipid, calcium, phosphorus and protein density around the same skeletal environment. Raw honey provides glucose and fructose together with enzymes and plant-derived compounds, while effects of its endogenous enzymes on DHT, T3, or adult facial growth have not been established in human experiments. Orange juice, sugar-cane juice and dates provide rapidly available carbohydrate that can help prevent chronic low-energy availability, while coconut cream gives another dense fat source. Raw oysters are particularly interesting because of their zinc density. Human zinc-depletion experiments show that low zinc can reduce circulating testosterone, while correction of zinc deficiency can restore it. PMID 8875519, PMID 1609752. That does not mean zinc infinitely raises testosterone; it means zinc sufficiency is required for normal gonadal physiology.

Raw vanilla extract, around 2 teaspoons in a smoothie or juice, fits easily into the food framework and adds vanillin and related aromatic phenolics. It blends naturally with raw milk, cream, honey or orange juice and adds a concentrated aromatic layer to the rest of the food.

Thyroid treatment addresses thyroid disease. T3 acts through TRα1/THRA in skeletal tissue and influences chondrocyte maturation, osteoblast differentiation, and matrix mineralization. Both deficient and excessive thyroid signaling can disrupt bone health (PMID 26862888, PMID 24783033; see the thyroid research library). Prescription T3, desiccated thyroid, and raw thyroid gland are not interchangeable approaches to improving facial appearance. Decisions about thyroid hormone treatment require a clinical assessment; skeletal T3 signaling alone does not establish a cosmetic benefit from supplementation.

The actual objective is therefore not to obsess over one hormone. You want an endocrine and mechanical environment where androgen receptor signaling, physiological DHT, GH/IGF-1, T3, progesterone-receptor biology, adequate energy availability and mechanical loading converge on osteoblasts and periosteal progenitors. Those cells then integrate endocrine signals with integrin → FAK/Src → RhoA/ROCK, PIEZO-mediated Ca²⁺ signaling, ERK and YAP/TAZ, eventually feeding transcriptional programs involving RUNX2, SP7, COL1A1, ALPL and matrix mineralization. These pathways explain how skeletal cells integrate biological signals. They do not supply a dose or predict an adult cosmetic result from a supplement or manual routine.
