Five Surprising Gut Triggers That May Be Sabotaging Your Skin

If you’ve ever felt like you’ve tried every cleanser, serum, or treatment but your skin still won’t calm down, you’re not alone. I see this all the time in my practice. Women investing in great products, facials, and routines, yet still dealing with stubborn breakouts, eczema flares, or rosacea. The truth? When skincare alone isn’t enough, it’s often the gut sending signals through the skin.

The gut and skin are closely connected through inflammation, immune balance, and nutrient absorption. When the gut is out of sync, your complexion often shows it. Here are five common (and often overlooked) gut triggers that may be sabotaging your skin, and what you can start doing about them.

1. Blood Sugar Swings

Frequent spikes and crashes in blood sugar don’t just leave you tired and craving more sugar, they also fuel inflammation and increase oil production, setting the stage for breakouts. Over time, unstable blood sugar can make skin appear more reactive and less resilient.
What to try: Start your day with a protein-rich breakfast, pair fruit with nuts or seeds, and aim for meals that balance protein, healthy fat, and fiber.

2. Alcohol and Wine

That rosacea flare after happy hour? It’s not in your head. Alcohol, especially wine, can disrupt gut balance, dehydrate the body, and increase inflammation, all of which show up on the skin. It can also impact sleep quality, leaving skin looking dull or inflamed.
What to try: If you drink, alternate alcohol with sparkling water, stay well-hydrated, and try alcohol-free days (or mocktails) during the week to give your gut and skin a break.

3. Low Fiber Intake 

Fiber is the foundation of a healthy microbiome, but most women get far less than they need. The goal is about 25–35 grams of fiber per day, yet the average intake falls far short. Without enough fiber, gut bacteria diversity declines, which can show up on the skin as dryness, dullness, or more frequent flares.

What to try: Aim to “eat the rainbow.” Add leafy greens, colorful vegetables, fruits, beans, and gluten-free whole grains to bring more variety and more fiber onto your plate each day.

4. Hidden Food Sensitivities

Sometimes the food we eat every day can be the very ones driving inflammation beneath the surface. Dairy, gluten, or even certain additives can aggravate the gut lining, which in turn can trigger acne, eczema, or redness. It’s not always obvious, and sensitivities are highly individual.
What to try: Pay attention to patterns between what you eat and how your skin feels. If flare-ups are consistent, it may be worth exploring further with testing and guidance.

5. Stress and Sleep 

Stress hormones directly impact gut balance, while poor sleep weakens both gut and skin repair. The result? A double hit that often shows up as breakouts, dullness, or dry, reactive skin.

What to try: Prioritize a consistent sleep routine and build in daily stress-relievers, even short walks, journaling, or a few deep breaths can shift the stress response and benefit both gut and skin.

Skincare products absolutely play a role, but lasting change often requires looking deeper. Supporting your through diet and lifestyle creates the foundation for healthy, resilient skin and overall health and well-being.

In my practice, I use advanced functional testing like the GI-MAP to examine the gut microbiome and uncover hidden imbalances, sensitivities, or nutrient gaps that can drive chronic skin issues. These are the pieces topical products can’t address on their own, and where personalized nutrition and gut support make the biggest difference.
