The Gut-Skin Connection: How Your Digestive Health Impacts Acne (and How to Fix It)
If you’ve been struggling with acne, you’ve probably tried everything—cleansers, serums, prescription creams, antibiotics, and even harsh acne medications. But what if the real cause of your breakouts isn’t on your skin—it’s in your gut?
Science is increasingly confirming what naturopaths have known for years: your gut health plays a crucial role in your skin health. The state of your microbiome (the trillions of bacteria living in your digestive system) can influence inflammation, hormone balance, and even how your skin regulates oil production.
If you’ve been treating acne from the outside without success, it’s time to take a closer look at your gut health.
How Poor Gut Health Triggers Acne
Your gut and skin are intimately connected through the gut-skin axis, a two-way communication system where imbalances in the digestive system show up on your skin. Here’s how:
1. Gut Dysbiosis (Imbalanced Microbiome) Fuels Inflammation
Your gut microbiome should contain a balanced mix of beneficial and harmful bacteria. When the bad bacteria take over (a condition called dysbiosis), they trigger chronic inflammation, which can manifest as red, inflamed acne.
Signs of dysbiosis:
Bloating, gas, or irregular bowel movements
Food intolerances or sensitivities
Brain fog, fatigue, or low mood
Actionable Step: Increase your intake of fermented foods like sauerkraut, kimchi, and kefir, or take a high-quality probiotic to restore gut balance.
2. Leaky Gut Allows Toxins to Reach Your Skin
When your gut lining becomes compromised, toxins and undigested food particles can escape into the bloodstream—a condition known as leaky gut (intestinal permeability). This can over-activate your immune system, triggering inflammation that worsens acne.
Signs of leaky gut:
Skin flare-ups after eating certain foods
Autoimmune conditions
Persistent bloating and digestive discomfort
Actionable Step: Support your gut lining with bone broth, L-glutamine, zinc, and aloe vera to promote healing.
3. Poor Gut Health Contributes to Hormonal Imbalances
Your gut plays a huge role in metabolizing and regulating hormones. If it’s not functioning properly, you can end up with excess androgens (male hormones like testosterone), which increase oil production and lead to hormonal acne, particularly around the jawline and chin.
Signs of hormone-driven acne:
Breakouts that worsen around your menstrual cycle
Oily skin and deep, cystic acne
PCOS or irregular periods
Actionable Step: Balance hormones naturally by supporting your liver (with bitter greens and dandelion tea), managing stress, and reducing dairy and sugar (which can spike androgens).
4. Slow Digestion and Constipation Lead to Toxin Build-Up
Your body eliminates waste—including excess hormones and toxins—through your bowel movements. If you’re constipated or not digesting food well, these toxins get reabsorbed into your bloodstream, leading to inflammation and breakouts.
Signs of sluggish digestion:
Less than one bowel movement per day
Feeling full or bloated after meals
Skin breakouts that coincide with digestive issues
Actionable Step: Improve digestion with fiber-rich foods (flaxseeds, chia seeds, leafy greens), digestive bitters, and adequate water intake to keep things moving.
5 Steps to Heal Your Gut and Clear Your Skin
If you suspect your gut is driving your acne, here’s how you can start healing:
Step 1: Remove Gut Disruptors
Certain foods and lifestyle habits damage your gut and fuel acne-causing inflammation.
Cut back on:
Refined sugar (which feeds bad bacteria and spikes insulin)
Dairy (which increases androgens and contributes to clogged pores)
Gluten (which can trigger inflammation in sensitive individuals)
Processed foods and seed oils (which promote oxidative stress)
Instead, focus on whole, anti-inflammatory foods that nourish your gut and skin.
Step 2: Replenish Beneficial Bacteria
To rebuild a healthy microbiome, add probiotic-rich and prebiotic foods into your diet.
Probiotics: Yogurt (dairy-free if sensitive), sauerkraut, kimchi, kefir, miso
Prebiotics (gut bacteria food): Garlic, onions, leeks, asparagus, bananas
If you need additional support, consider a multi-strain probiotic supplement with Lactobacillus and Bifidobacterium strains, which are linked to reduced skin inflammation.
Step 3: Support Gut Healing
Healing your gut lining helps reduce leaky gut and inflammation, leading to clearer skin.
Add gut-healing nutrients like:
Bone broth & collagen (for gut lining repair)
L-glutamine & zinc (to reduce intestinal permeability)
Step 4: Improve Detoxification & Digestion
If your liver and digestion aren’t functioning optimally, toxins build up and contribute to acne.
Support detox pathways with:
Dandelion tea & bitter greens (stimulates bile production for better digestion)
Flaxseeds & psyllium husk (promotes regular bowel movements)
Liver-supporting herbs like milk thistle and turmeric
Step 5: Reduce Stress & Prioritize Sleep
Stress directly impacts gut health and skin by increasing cortisol, which triggers inflammation, oil production, and breakouts.
To reduce stress and support gut healing:
Get 7-9 hours of sleep per night
Practice deep breathing, meditation, or yoga
Spend time outdoors to regulate cortisol levels
