If you’ve tried everything: skincare routines, spot treatments, probiotic powders, cutting dairy, only to still wake up with breakouts… this might explain why.
Most acne content online talks about the what: oily skin, clogged pores, hormones. But almost no one talks about the why. Why does your skin react the way it does, even when you're using all the right products?
Here are 5 surprising, science-backed causes of breakouts most people don’t know about—and what to do about them.
As featured in..
Gut Imbalance: The Skin-Disrupting Signals in Your Microbiome
Your skin isn’t just breaking out because of what’s happening on the surface; it’s reacting to inflammation in your gut.
When your gut is out of balance (from antibiotics, ultra-processed foods, or stress), it sends out inflammatory signals that show up on your face. Studies show a clear gut-skin axis: what’s brewing in your digestive system directly impacts oil production, sensitivity, and breakouts.
What helps:
- Add fermented foods (like sauerkraut or kefir) to your diet.
- Avoid artificial sweeteners—they feed the wrong bacteria.
- Look for a probiotic that includes Lactobacillus rhamnosus or Bifidobacterium lactis—these have been linked to improved skin clarity.
1 Capsule, 20 Nutrients
You don’t need PCOS or a known hormonal issue to have hormone-triggered acne.
Modern stress, poor sleep, and fluctuating blood sugar can spike androgens (male hormones like testosterone) that fuel oil production and inflammation. This is especially common in your 20s and 30s—even if your cycle seems “normal.”
What helps:
- Stabilise blood sugar by eating protein with breakfast, not just coffee.
- Cut back on caffeine post-lunch—it spikes cortisol.
- Try supplements that support hormonal balance (zinc, vitamin B6, DIM).

Liver Overload: Your Skin is Picking Up the Slack
Your liver is responsible for detoxing excess hormones, inflammatory byproducts, and environmental toxins.
When it's overworked—thanks to alcohol, synthetic skincare, or even certain medications—your skin becomes a secondary detox organ. Translation? More breakouts, dullness, and redness.
What helps:
- Reduce your alcohol intake (even one glass of wine per night impacts detox enzymes).
- Support your liver with cruciferous veggies (like broccoli, kale, and cauliflower).
- Look for ingredients like milk thistle or N-acetyl cysteine (NAC) for liver support.

Chronic Inflammation: The Silent Skin Saboteur
You may not feel it, but low-grade inflammation can simmer under the surface for years—triggered by poor sleep, ultra-processed foods, or even that low-level stress you’ve “gotten used to.”
What helps:
- Prioritize 7–8 hours of sleep (your skin heals overnight).
- Add anti-inflammatory nutrients like omega-3s and turmeric to your routine.
- Practice nervous system resets daily—like a 5-minute walk or 2 minutes of deep breathing.

Nutrient Depletion: Your Skin is Starving for the Basics
Modern diets are often low in zinc, selenium, and certain B-vitamins—all crucial for clear skin.
Birth control, caffeine, alcohol, and stress deplete these nutrients even further, creating a silent deficiency that shows up as breakouts, rough texture, or “slow healing” spots.
What helps:
- Take a high-quality multivitamin or skin-specific supplement.
- Eat more Brazil nuts (selenium), pumpkin seeds (zinc), and leafy greens (B vitamins).
- Look for supplements that use bioavailable forms (like methylated B12 and zinc picolinate).
Here’s the good news: You don’t need 5 different protocols to address these.
There’s one clear-skin solution that targets all five hidden causes in a single daily habit.

Frequently Asked questions
Need more information? You can find it here.
Still have questions? Contact us: care@mondaymuseskin.com
Can I use this supplement if I'm on birth control?
Yes, you can use The Skin Clarity Complex while on birth control. Birth control can potentially deplete important nutrients like B vitamins (especially B6, B12, and folic acid), as well as vitamins C and E, magnesium, and zinc. Our skin supplement is formulated with high-quality vitamins, including Vitamin B6 and C, minerals (zinc), and probiotics designed to help replenish these nutrients, supporting overall health and skin wellness.
What's the timeframe for results?
For best outcomes, it's recommended to use The Skin Clarity Complex for at least 3 months. However, you can expect a reduction in symptoms within a month of daily usage. In some cases, individuals may notice effects within a few weeks, while in others, it may take weeks or months of consistent use to observe changes. It's essential to follow recommended dosage and give the supplement sufficient time to take effect before expecting results.
Can I take this with other supplements?
For a personalized supplement routine, we recommend discussing it with your healthcare provider. Our supplement is designed as a 3-in-1 product: it serves as your multivitamin, probiotic, and skin support supplement. As a result, you may not need additional supplements. However, everyone's needs are different, so it's best to consult your healthcare provider to confirm your routine.
Can anyone take it?
Our supplement is a 3-in-1 formula containing 10 billion probiotics, 6 plant extracts, 4 essential minerals, and 4 vitamins. While it's designed to benefit many, it's important to consult your healthcare provider to determine if it's right for you, especially if you have specific health conditions or are taking medication.
When is the best time to take it?
We suggest taking The Skin Clarity Complex in the morning
with food, but you can take it any time of the day.
Can I take The Skin Clarity Complex while using acne medication?
The Skin Clarity Complex tackles diverse acne symptoms internally through an oral supplement containing a mix of vitamins, minerals, and probiotics that work on a cellular level. Before starting The Skin Clarity Complex, we recommend consulting your healthcare provider to confirm compatibility with any current prescription medication, whether topical or oral.
Is it advisable to take it during pregnancy or while breastfeeding?
Please consult with your
doctor before using The Skin.
Is The Skin Clarity Complex Vegan and free from gluten, nuts and fillers?
The Skin is both gluten-free and
nut-free. Its also 100% vegan, cruelty-free, free of fillers & sugars.
Is it suitable for individuals under 18?
We suggest this product for ages 16 and above.
Please consult your healthcare provider for personalised guidance.
Where is The Skin Clarity Complex produced?
The Skin Clarity Complex is manufactured in the UK.
Are the supplements safe to take long-term?
Yes, our supplements are made of beneficial minerals, vitamins, probiotics, and more, designed for daily use. For long-term maintenance, once you've achieved your desired results, you can reduce to one capsule a day or the full dose a few times a week based on your needs. It's important to take an intuitive approach and consult your doctor if you're on medication.
Does the supplement contain caffeine?
Our formula includes a small amount of green tea (10 mg). Since 7% of this is caffeine, it amounts to just 0.7 mg of caffeine. To put this in perspective, a typical cup of coffee contains about 95 mg of caffeine, so the caffeine level in The Clarity Complex is extremely minimal.
Do I need a multivitamin too?
Our supplement contains many essential multivitamins along with key vitamins, minerals and probiotics that support gut and immune health. While multivitamins are typically taken for general health, our supplement is designed to address skin issues, general health, gut health, and hormone health. If you have these specific needs, we suggest opting for the Clarity Complex instead of a regular multivitamin.
Are the ingredients in the supplement third-party tested?
Yes, our ingredients are third-party tested for heavy metals and microbes. Our product is manufactured according to GMP guidelines, ensuring compliance with all relevant UK & EU regulations related to food supplements. This includes the regulation on PAHs 2015/1993 and standards for heavy metals and microbiological criteria. Additionally, our ingredients are verified to be non-GM and non-irradiated. We confirm our product adheres to current EU regulations concerning microbacterial levels, heavy metals, and PAHs for food supplements as it is made in England.
