Acne is often dismissed as a teenage problem. But many adults continue to struggle with breakouts well into their 30s and 40s.

You may notice:

• persistent breakouts on the chin or jawline
• oily or inflamed skin
• painful cystic acne
• breakouts around your menstrual cycle
• acne that worsens with stress
• digestive issues alongside skin flare-ups

Most treatments focus on topical creams, antibiotics or medications. These may reduce symptoms temporarily, but they rarely address the internal drivers that are causing the skin to break out.

Acne is not simply a skin issue. It is most often a gut, systemic inflammation and hormone regulation issue that shows up on the skin.

Acne develops when several processes happen at the same time:

• excess oil production
• clogged pores
• bacterial imbalance on the skin
• inflammation in the body
• hormonal signaling changes

When these factors combine, pores become blocked and inflamed, leading to breakouts.

But these changes are usually being influenced by deeper drivers such as:

• gut health imbalance
• blood sugar instability
• hormone fluctuations
• toxin buildup
• chronic inflammation

This is why treating acne effectively often requires addressing the internal environment.

Acne rarely has a single cause. Most people develop breakouts when several systems in the body are under strain.

High-glycemic diets can increase insulin levels. Elevated insulin stimulates androgen hormones, which increase oil production in the skin.

This is why acne is often worsened by:
• sugary foods
• refined carbohydrates
• sweet drinks

How to support this: Balanced meals that include protein, fibre and healthy fats help stabilise blood sugar and reduce hormonal triggers.

The liver plays an important role in clearing excess hormones and environmental toxins. When detox pathways are overloaded, inflammatory compounds can build up in the body and affect the skin.

How to support this: Supporting liver function through nutrition and targeted nutrients helps the body process and eliminate inflammatory compounds.

Omega-3 fatty acids help regulate inflammatory signalling in the body. Modern diets are often high in omega-6 fats and low in omega-3s, which can promote inflammatory skin conditions.

How to support this: Increasing omega-3 intake helps calm inflammation and support skin barrier health

Stress hormones increase oil production and inflammatory signaling. Many people notice acne worsening during periods of emotional stress or poor sleep.

How to support this: Improving sleep quality and nervous system balance helps regulate hormonal and inflammatory pathways.

Improving acne requires calming inflammation, supporting gut health and restoring hormone balance.

Certain foods commonly worsen inflammatory skin conditions.

These include:
• refined sugar
• ultra-processed foods
• excessive dairy
• inflammatory seed oils (sunflower, soybean, canola)

💡 Small Step, Big Win: Replace sugary drinks and processed snacks with whole foods such as fruit, nuts or yoghurt.

A healthy gut microbiome supports immune regulation and reduces systemic inflammation.

💡 Small Step, Big Win: Start your day with a glass of GutShield+ to repair and rebalance the gut microbiome.

Blood sugar spikes increase insulin and androgen hormones.

💡 Small Step, Big Win: Build meals around protein, vegetables and healthy fats instead of refined carbohydrates.

Your liver processes hormones and environmental toxins. Supporting this system helps reduce inflammatory load.

💡 Small Step, Big Win: Add cruciferous vegetables such as broccoli, cabbage or cauliflower to one meal daily and sip on a glass of DetoxShield+ to help remove toxins and balance hormones.

Omega-3 fats help calm inflammatory pathways involved in acne.

💡 Small Step, Big Win: Eat fatty fish such as salmon or sardines three times per week, include chia seeds or olive oil in your meals daily or supplement with omega-3 daily.

Stress worsens hormonal fluctuations and inflammatory signaling.

💡 Small Step, Big Win: Spend 10 minutes outdoors in natural light each morning to regulate your circadian rhythm.

Acne is rarely just a skin problem. It is often a reflection of inflammation, hormone imbalance and gut health.

When these internal systems are supported, many people see significant improvements in their skin. Instead of fighting symptoms on the surface, the goal is to restore balance inside the body.
