Dark circles are one of the most common concerns I hear about in my practice, and also one of the most consistently misunderstood. Most people reach for concealer, buy a new eye cream, or blame another bad night of sleep. And while sleep absolutely matters, dark circles that persist regardless of how much rest you get, or that seem to deepen over the years, are likely not just a sleep problem.
In Chinese Medicine, the area beneath the eyes is one of the most diagnostically rich regions of the entire face. It reflects the state of an organ system that Western medicine has no direct equivalent for — the "Kidney System" — and what shows up there tells a story that goes back years, sometimes decades, and even may connect to one’s ancestral trauma.
This post is a deep dive into all of it: the Western dermatology explanation, the TCM framework, the surprisingly well-researched link between unprocessed trauma and the kind of chronic low-grade inflammation that quietly depletes the "Kidney energy" over time and, what you can actually do about it all.
What Western Dermatology Says About Under-Eye Circles
Before we go into the Chinese Medicine lens, it's worth understanding what conventional dermatology has identified as the causes of periorbital hyperpigmentation and dark circles.
Research published in the Journal of Cosmetic Dermatology [1] identifies four primary structural mechanisms:
1. Vascular pooling. The skin beneath the eyes is the thinnest skin on the body, sometimes only half a millimeter thick. The tiny capillaries and blood vessels sitting just beneath the surface become visible, creating a blue-purple hue. Fatigue, dehydration, and poor circulation all worsen this, as does anything that increases venous pressure in that area (including chronic sinus congestion and allergies).
2. Periorbital hyperpigmentation. This is a melanin-based darkening that develops with age, sun exposure, and genetic predisposition, and is more pronounced in those with darker skin tones. It is associated with post-inflammatory hyperpigmentation from eczema, rubbing the eyes, and disrupted skin barrier function [2].
3. Structural shadowing. As we lose subcutaneous fat and collagen under the eyes with age, a hollowing occurs. The shadow cast by this depression reads visually as dark — even when the skin tone itself hasn't changed. This is a structural issue, not a pigmentary one, and it deepens over time as "Kidney Yang energy" declines (more on this shortly).
4. Nutritional and systemic causes. Iron deficiency anaemia, zinc deficiency, thyroid dysfunction, and chronic fatigue are all documented contributors to periorbital darkness [3]. These are not cosmetic issues, but rather metabolic ones.
What's important to note is that for many people, all four mechanisms are happening simultaneously, which is why a single eye cream is rarely a meaningful solution.
What Chinese Medicine Sees
Chinese Medicine looks at the same anatomy — the hollowing, the darknening, the puffiness — and reads something equally as systemic, though with a much different lens.
In TCM, every region of the face corresponds to an internal organ system. The area directly below the eyes reflects the state of the Kidneys. When Kidney energy is deficient, whether through depletion, overwork, chronic fear, or simple aging, it shows up here first.
The Kidneys in Chinese Medicine are not simply the organs that filter blood. (*Capitalized to denote the difference between the kidney organs and the "Kidney System".) They are considered the “root of all Yin and Yang” in the body. They house Jing (精), the foundational essence that governs our growth, reproduction, and aging process. Jing is often described as our constitutional battery: partly inherited from our parents at birth, partly replenished through food, rest, and right living. When Jing is abundant, the skin is luminous, the eyes are bright, the lower face is full and lifted. When Jing is depleted, the face hollows, the under-eye darkens, the hair becomes grey, and the lower back aches.
There are two primary Kidney deficiency patterns that produce dark circles, and they look slightly different on the face:
Kidney Yin Deficiency tends to produce a deeper darkness beneath the eyes, sometimes accompanied by dryness, fine lines in the under-eye area, a feeling of heat in the palms and soles at night, and difficulty staying asleep between 2–4am. The face often looks older than the person's years.
Kidney Yang Deficiency tends to produce a more puffiness-plus-darkness pattern often with a bluish-black tone accompanying fluid retention. These individuals often feel cold, especially in the lower body, have low energy in the morning, low libido, and retain water.
Many people present with a combination of both, particularly in midlife.
The Classical Chinese Medicine View: Kidney Energy Over a Lifetime
To understand why Kidney deficiency matters so much for longevity and appearance, we need to go back to the source.
The Huangdi Neijing (黃帝內經),the Yellow Emperor's Classic of Medicine, compiled between approximately 300–100 BCE, describes the natural arc of human vitality in terms of seven-year cycles for women and eight-year cycles for men [4]. This framework is one of the most elegant models of aging in any medical tradition, and it remains clinically relevant today.
For women, the Neijing describes it as follows:
> At age 7, the Kidney energy becomes exuberant, the teeth change, and the hair grows long.
> At 14, the Tiangui (天癸) — the heavenly water, understood as the hormonal essence that governs reproduction — arrives. Menstruation begins.
> At 21, the Kidney energy is balanced and full. Wisdom teeth emerge.
> At 28, the body is at its peak. Tendons and bones are strong, hair long and abundant.
> At 35, the Yangming (stomach and large intestine) channels begin to decline. The face begins to wither. Hair begins to fall.
> At 42, the three Yang channels all weaken. The face withers more noticeably, hair begins to turn.
> At 49, the Tiangui is exhausted. Menstruation ceases. The body can no longer conceive.
For men, the cycle is in eight year increments of decline: peak Kidney energy at 16 (Tiangui), full strength at 32, the first signs of decline at 40, and notable Kidney deficiency at 56.
What this framework illuminates is that dark circles, hollowing beneath the eyes, and a loss of facial luminosity are not aberrations; rather, they are natural consequences of Jing moving through this gradual and natural process of depletion. The question is not how to stop the process, but how to steward it wisely. The Neijing is explicit: those who live in alignment with the Tao, meaning sufficient sleep, regulated emotions, nourishing food, seasonal living, and the cultivation of inner stillness, preserve their Jing far longer than those who do not.
The classical text uses the phrase 腎藏精 — "the Kidney stores Essence" — and elsewhere, 肝腎同源 — "the Liver and Kidney share the same source." This is clinically important. The Liver in Chinese Medicine opens to the eyes; the Kidneys nourish the Liver. When Kidney Jing is depleted, the Liver Blood that feeds the eyes is also compromised, which is why Kidney deficiency and Liver Blood deficiency so often appear together in the under-eye area as simultaneous darkness and dryness. Overuse of the eyes themselves, whether through excessive working, scrolling, or sensory stimulation, is also said to deplete "Liver Blood", contributing to the quickening degeneration of the body. (Learn more about the way the "Liver System" impacts the complexion and can create a dullness in the face in this blog post)
The Lingshu (靈樞), the companion volume to the Suwen, describes the eight extraordinary channels (vessels that carry Jing throughout the body) and their relationship to the face. The Du Mai (督脈), Ren Mai (任脈), and Chong Mai (衝脈) are all rooted in the Kidneys and travel upward through the torso and face. When these vessels are depleted, which can happen for a variety of both physical and psychological reasons including overworking, poor quality sleep, unprocessed trauma, heavy menstruation, improper recovery from pregnancy, excessive ejaculation, and so on, the face loses its root of nourishment, and begins to show the consequences.
The Role of Unprocessed Trauma
This is once of the causes for persistent circles under the eyes that surprises patients, and where the research is more robust than most people expect.
Trauma is not simply a psychological experience. It is a physiological one. And when it goes unprocessed, i.e. when the body never fully completes its stress response, never receives the signal that the threat has passed, it remains embedded in the nervous system, the fascial tissue, and the hormonal axis in ways that cause measurable, ongoing biological harm.
The landmark ACE (Adverse Childhood Experiences) Study, published in the American Journal of Preventive Medicine in 1998 [5], followed over 17,000 adults and found a graded dose-response relationship between the number of childhood adversities experienced and nearly every major chronic disease in adulthood, including autoimmune conditions, cardiovascular disease, and accelerated cellular aging. The more adverse experiences, the more biological disruption, regardless of current circumstances.
Dr. Bessel van der Kolk's foundational work The Body Keeps the Score [6] synthesizes decades of trauma research to show that traumatic memory is stored not abstractly, but somatically in the body's postural patterns, autonomic responses, and chronic inflammatory states. The body remains in a state of low-grade vigilance long after the original threat is gone.
Biologically, unprocessed trauma keeps the HPA (hypothalamic-pituitary-adrenal) axis in a state of chronic dysregulation. A 2015 systematic review and meta-analysis published in Lancet Psychiatry [7] found that people with PTSD had significantly elevated levels of inflammatory markers including C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α), compared to non-traumatized controls. These are not subtle differences. They represent a body that is chronically inflamed, chronically on alert.
This matters for the skin directly. A widely-cited review in Inflammation & Allergy Drug Targets [8] describes what researchers now call the "brain-skin connection" — the bidirectional communication between the central nervous system and the skin via the HPA axis, the autonomic nervous system, and neuropeptide signaling. Chronic psychological stress accelerates skin aging, impairs wound healing, disrupts the epidermal barrier, and depletes the skin of the minerals and growth factors needed for repair. Elevated cortisol, in particular, directly suppresses collagen synthesis, breaks down existing collagen and elastin, impairs microcirculation, and depletes zinc, magnesium, vitamin C, and B vitamins, all of which are required for skin fullness, tone, and repair [9].
Epel et al.'s landmark 2004 study in the Proceedings of the National Academy of Sciences [10] found that chronic psychological stress, including caregiver stress and early life adversity, was associated with significantly shorter telomeres, a direct marker of cellular aging. The women with the highest stress burden had telomeres equivalent to those of women a decade older. This is the body aging faster at a cellular level.
The under-eye area is particularly vulnerable to all of this, because it is already the thinnest skin on the face, already dependent on microcirculation that stress directly impairs, and already closely tied to the organ system (the Kidneys/adrenals) that bears the brunt of chronic stress load.
The TCM View: How Trauma Depletes the Kidneys
In Chinese Medicine, fear is the emotion of the Kidneys. Acute fear — a sudden shock — is said to "scatter the Kidney Qi." Chronic, low-grade fear or anxiety is said to slowly consume the Kidney Jing. The relationship is not metaphorical; it is clinical. Patients who have lived with chronic anxiety, hyper-vigilance, or unresolved shock consistently present with Kidney deficiency patterns: dark circles, lower back weakness, night sweats, early morning waking, hair thinning, and a quality of underlying exhaustion that no amount of sleep seems to fully resolve.
This is because in TCM, the Kidneys govern the adrenal glands (which sit directly on top of the kidneys). Chronic activation of the stress response, the cortisol-adrenaline cascade, over months and years is a direct drain on what the Neijing would call Kidney Yang and, over time, Kidney Jing itself. This is not a distant metaphor. It is a direct parallel to what Western medicine describes as HPA axis dysregulation, adrenal fatigue, and the downstream depletion of DHEA, testosterone, and other steroid hormones that are manufactured from the same precursors as cortisol.
When the adrenals are chronically recruited for survival rather than available for restoration, the downstream effects are precisely what both Chinese and Western medicine describe: thinning skin, poor wound healing, mineral depletion, immune dysregulation, impaired fluid metabolism (leading to puffiness beneath the eyes), and a generalized loss of vitality that shows on the face long before it registers as disease.
Qigong and Lifestyle: How to Preserve Kidney Jing
The Huangdi Neijing is remarkably specific about preservation. The foundational instruction is this: live in alignment with the seasons, protect the Jing from unnecessary expenditure, and cultivate stillness as a form of replenishment. (But how to follow these tips while hustling to achieving massive success?! You may ask…stay tuned for a future blog post on this.)
In practical terms, this translates to the following (some of which are two thousand years old, and all of which have contemporary physiological support):
Sleep before midnight. The Neijing describes midnight as the turning point between Yin and Yang, the moment when the body shifts from expenditure to restoration. Chronic late-night activity is considered one of the most direct ways to deplete Kidney Yin over time. Modern research aligns: sleep between 10pm and 2am corresponds with the deepest phases of HGH (human growth hormone) secretion and cellular repair [11].
Protect the lower back and lower body from cold. The Kidney meridian originates at the sole of the foot (Kidney 1 — 涌泉, Yongquan, "Bubbling Spring") and runs up the inner leg and spine. Cold feet, sitting on cold surfaces, and exposing the lower back are all considered Kidney-depleting in classical texts. Warming the lower body with appropriate clothing, warm foot soaks, wearing slippers or socks on non-carpeted floor, and keeping the mingmen (命門, Gate of Life — the point between the kidneys at the lumbar spine) warm are foundational Kidney-preservation practices. This also includes avoiding excessive "cold foods" (both in temperature and in their effect on the physiology once consumed), such as smoothies, dairy products, and raw salads.
Kidney Qigong. The Ba Duan Jin (八段錦), or Eight Brocades, one of the most widely practiced Qigong forms in history, contains a specific movement, "Two Hands Hold the Feet to Strengthen the Kidneys and Waist", designed to stimulate Kidney Qi through the Du Mai and the Kidney Back-Shu points (膀胱經, Bladder 23). The Six Healing Sounds system includes the Kidney sound "Chui" (吹), practiced with a specific breath and visualization of blue-black water to cleanse and tonify (strengthen) Kidney energy. Research on Qigong practice has documented reductions in cortisol [12], improvements in autonomic balance, and improvements in perceived vitality and sleep quality, all of which correspond to Kidney restoration from a TCM perspective. (Try this Kidney Qigong Practice on my YouTube Channel)
Self-massage of the Kidney Shu points. Rubbing the lower back vigorously with the backs of the hands until warm, a practice described in classical texts and taught in virtually every Kidney Qigong sequence, stimulates the 腎俞 (Shenshu, Bladder 23) points directly, which are said to help regenerate the kidney organs themselves. This is one of the simplest and most accessible practices available, and it can be done in under two minutes each morning.
Nourish with black and dark foods. The Kidneys are associated with the Water element and the color black. Classical dietary medicine emphasizes black sesame seeds (黑芝麻), black beans, seaweed, dark leafy greens, walnuts (which physically resemble the brain, the "sea of marrow" also governed by the Kidneys), goji berries (which are said to nourish Kidney Yin and Liver Blood simultaneously), and bone broth (rich in minerals and collagen precursors that directly support the Jing).
Cultivate stillness and address the emotional root. This is perhaps the hardest and the most important. If the depletion has a trauma root, and for many people it does, no herb or Qigong practice will fully resolve it without also addressing what is held in the body. Somatic therapies, EMDR, breathwork, and trauma-informed movement practices all support the nervous system's ability to complete its stress response and come out of a state of chronic vigilance. In TCM terms, this is the work of calming the Shen (心神) and allowing the Kidneys to stop functioning as a 24-hour emergency generator.

What Cosmetic Acupuncture Does for Kidney Deficiency
If you want to understand exactly what your under-eye area (and the rest of your face) is telling you about your internal landscape, Class 3 of the Glow From Within series is where we go deep.
In the next upcoming live class, we will unpack what most beauty treatments skip entirely: the face is a diagnostic map. Every region, every line, every area of discoloration or hollowing corresponds to an organ system; and when we treat from that understanding, the results go far beyond what topical products alone can achieve.
In this upcoming class, "The Natural Face Lift" (Class 3), we cover how cosmetic acupuncture works, not just to relax muscles or stimulate collagen, but to move stagnant Qi and Blood in the face and restore circulation to depleted areas, how to read facial patterns as a form of ongoing self-diagnosis, and how the under-eye area, the jawline, the forehead, and the cheeks each carry specific information about what is happening internally.
Beauty, in Chinese Medicine, is never separate from health. The Glow From Within natural beauty masterclass series is where that philosophy becomes a practical skill.

Nourishing the Kidneys From the Inside Out — Food, Herbs & Supplements
If the undereye area is calling for attention, the most powerful long-term intervention is not topical. It is nutritional and herbal, which is exactly what we cover in Class 4 of Glow From Within: Food, Supplements, and Herbs for Glowing Skin and Kidney Health
Some of the Kidney-specific herbs and nutrients we will discuss in class:
He Shou Wu (何首烏) / Fo-Ti — one of the most celebrated Kidney Jing tonics in classical herbalism, traditionally used for hair, skin, and anti-ageing. Modern research has investigated its effects on telomerase activity and cellular longevity.
Shu Di Huang (熟地黃) / Prepared Rehmannia — the foundational Kidney Yin tonic in Chinese medicine. Used in the classical formula Liu Wei Di Huang Wan (六味地黃丸 — Six Flavor Rehmannia Pill), which remains one of the most prescribed herbal formulas globally for Kidney Yin deficiency.
Gou Qi Zi (枸杞子) / Goji Berries — nourish both Kidney Yin and Liver Blood, directly addressing the Kidney-Liver axis that governs eye health and under-eye appearance. Rich in zeaxanthin and betaine.
Nu Zhen Zi (女貞子) / Ligustrum — a cooling, restorative Kidney Yin tonic often paired with Han Lian Cao (旱蓮草 / Eclipta) in the classical formula Er Zhi Wan (二至丸), one of the simplest and most elegant Kidney Yin formulas in the classical canon.
On the Western nutrition side: zinc (essential for collagen synthesis, immune regulation, and wound healing — frequently depleted by chronic stress), iron (anaemia is a direct cause of periorbital darkness), magnesium (depleted by cortisol and essential for sleep and HPA axis regulation), collagen peptides with vitamin C (supporting the structural fullness of the undereye area), and omega-3 fatty acids (reducing systemic inflammation and supporting skin barrier integrity).
Class 4 goes into the research, the dosing, the food sources, and how to think about building a supplement and herbal medicine regimen that actually matches your constitution and unique symptom presentation, rather than following a generic protocol that may not suit your body.

The Bigger Picture
Dark circles are, in one sense, a small cosmetic concern. In another sense, they are a window into how you have been living...how much you have rested, how much you have pushed, what you have carried without support, and where the body has quietly been spending reserves it cannot afford to keep spending.
The beautiful thing about Chinese Medicine is that it offers not just a diagnosis, but a direction. Kidney deficiency is not a verdict. It is an invitation: to sleep earlier, to eat more "Kidny-nourishing" foods, to practice Qigong or other mind-body awareness practices, to bring warmth to the lower half of the body, and to address what the nervous system is still holding. The face will respond, not overnight, but over time, in the way that all genuine restoration works: slowly, from the root.
In Chinese Medicine, the under-eyes are the window to understanding the speed at which you are depleting your "root", the Kidneys, and through this understanding, the Kidney health reveals the whole arc of how you have lived, and how you choose to live now.
