Skin Health Is an Inside Job: Root Causes of Acne, Eczema, Rosacea, and Dry Skin
Skin Health Is an Inside Job
Are you struggling with chronic skin issues like acne, eczema, rosacea, or persistently dry, dull skin?
If your answer is yes, chances are you’ve already tried a lot: diet changes, eliminating foods, “clean” skincare, supplements, prescription topicals, maybe even medications.
Some of those strategies may have helped temporarily - but the flares keep coming back. And you’re likely tired of feeling like your skin is something you have to constantly manage or suppress.
Skin issues are more than just aesthetic. They can take a real toll both physically and mentally — affecting confidence, self-expression, and how you show up in relationships, at work, and in everyday life. When your skin feels out of balance, it often impacts far more than what you see in the mirror.
Here’s the part that often gets missed when it comes to skin issues:
Skin health is an inside job.
Persistent skin issues are rarely just a surface-level problem.
Your skin is one of the body’s largest immune and detoxification organs. When there are deeper imbalances in the body - blood sugar, hormones, gut + digestion, detox pathways, nutrient status, nervous system - the skin often becomes the place where imbalance shows up.
In conventional healthcare, the focus is usually on symptom control: topical steroids, antibiotics, retinoids, hormonal suppression, spironolactone, accutane. While these tools can reduce symptoms, they don’t address why the skin is inflamed in the first place and they don’t come without side effects.
This is often what leads women down the path of extreme elimination diets, supplement overload, and chasing the “magic bullet” - without lasting results.
What Your Skin Might Be Communicating With You
Skin symptoms are not random. Patterns matter. Location matters. Timing matters.
Here are some of the most common root-cause drivers we see clinically:
Cystic, inflammatory jawline & chin acne
Often linked to:
Blood sugar instability and insulin signaling
Elevated cortisol (stress physiology)
Higher androgen activity or androgen sensitivity
Estrogen metabolism imbalance (not always “high estrogen,” but poor clearance)
This is why acne here often worsens around ovulation or the luteal phase—and why simply “balancing hormones” without addressing stress and metabolic inputs falls short.
Chin & cheek acne
Common drivers include:
Impaired gut barrier function and low-grade inflammation
Dysbiosis or gut microbe imbalances
Sluggish liver detoxification (especially phase II conjugation)
Chronic stress impacting immune signaling in the skin
The gut-skin axis is very real - gut inflammation and permeability are strongly associated with acne severity.
Eczema, psoriasis, or chronically reactive skin
Often reflects:
Immune dysregulation and gut imbalances
Histamine intolerance or mast-cell activation
Low zinc, vitamin A, omega-3s, or vitamin D
Impaired skin barrier integrity tied back to gut health
This is why topical steroids may calm flares short-term but often lead to rebound symptoms if the immune drivers aren’t addressed.
Rosacea, flushing, heat-triggered redness
Common root causes:
Cortisol imbalance and nervous-system hyperreactivity
Histamine excess or impaired histamine clearance
Gut dysbiosis
Impaired bile flow and detoxification
Rosacea is rarely just “sensitive skin”—it’s often a nervous-system + gut-immune story.
Dry + dull skin
Often points to:
Inadequate protein and essential fatty acids
Micronutrient depletion (like zinc, selenium, B vitamins, vitamin A)
Thyroid issues
Chronic under-fueling or low caloric intake
Poor circulation
Dehydration + low minerals
Low sex hormones
What We Assess in Functional Skin Cases
When we take a functional, root-cause approach to skin health, we’re not guessing and we’re not trying to simply suppress symptoms— we’re looking at the systems that most directly influence these skin issues and gathering detailed data to identify the specific mechanism driving a client’s unique skin issues.
In functional skin cases, we often assess:
Blood sugar + metabolic signaling
Fasting insulin and glucose patterns
Signs of reactive hypoglycemia or insulin resistance
How blood sugar swings may be driving inflammation and breakouts
How food, movements, stress and circadian rhythm habits are influencing blood sugar and insulin sensitivity
Hormone patterns (not just levels)
Androgen activity and metabolism
Estrogen metabolism and clearance (not just “high” or “low”)
Progesterone balance
Stress–hormone interactions
Gut health + digestion
Gut barrier integrity and inflammation
Dysbiosis or microbial imbalances
Bowel regularity and bile flow
Stomach acid and digestive enzymes
How gut health is influencing immune activation in the skin
Detoxification capacity
Liver phase I and phase II detox pathways
Estrogen and toxin clearance
Signs of detox congestion showing up through the skin
Nutrient status
Zinc, vitamin A, vitamin D
Essential fatty acids
B vitamins and minerals
Protein adequacy for skin repair and turnover
Immune + histamine balance
Histamine tolerance and mast-cell activity
Chronic immune activation
Patterns of reactivity, flushing, itching, or inflammation
Nervous system + stress physiology
Cortisol patterns
Nervous-system tone (fight/flight vs safety)
The role of chronic stress in skin flares
The goal isn’t to chase perfection — it’s to understand your unique skin and the specific drivers leading to skin symptoms so we can support the body in resolving skin issues from the inside out.
If you’ve been doing “all the right things” for your skin but aren’t seeing lasting change, it may be time to stop managing symptoms and to start understanding what your body is asking for.
This is exactly the kind of case we work with in 1:1 functional nutrition coaching — taking a whole-body, individualized approach to skin health that looks beyond products and surface level protocols.
