If you’ve ever noticed your skin flare up after a stressful week, a disrupted routine, or an indulgent weekend, you’re experiencing a real scientific phenomenon; the gut–skin axis. It’s one of the most fascinating areas of wellbeing research, and something that transformed how I think about both skincare and nutrition.
As someone who struggled with breakouts and dullness during stressful periods, I used to rely heavily on topical skincare. But the more I learned, and the deeper Purearth went into gut-health research, the clearer it became: healthy skin starts from within.
The gut–skin axis, explained simply
Your gut and your skin are constantly communicating. Through immune signalling, inflammation pathways, and your microbiome, what’s happening in your digestive system can show up directly on your face.
When your gut microbiome becomes unbalanced, through stress, poor sleep, diet changes, alcohol, or illness, it can trigger:
- inflammation
- reduced nutrient absorption
- increased skin sensitivity
- breakouts
- dullness
- flare-ups like eczema or rosacea
It’s not “in your head”, it’s biological.
Why digestion matters for your glow
Your skin relies on nutrients like vitamin C, vitamin A, zinc, and antioxidants. If your digestion is sluggish or your microbiome under strain, nutrient absorption decreases — and your skin feels the impact.
Healthy digestion and regularity help ensure that your body:
- absorbs nutrients needed for collagen
- reduces inflammation
- maintains hydration balance
- supports a healthy skin barrier
This is why gut health is the foundation of our Glow Kombucha and Pure Greens.
How supporting your gut helps your skin
When your digestion is supported with fibre, prebiotics, and live cultures, your skin often improves naturally. Many people using Glow Kombucha report clearer, calmer, more hydrated skin, not because of a topical treatment, but because their gut is functioning better.
Stress, the gut and your skin
Cortisol (the stress hormone) affects your gut first, and your skin immediately after. Stress reduces digestive enzyme efficiency, slows motility, and increases inflammation; all of which show up on your skin.
What actually helps?
- Live cultures help rebalance the microbiome
- Prebiotic fibre feeds beneficial bacteria
- Vegan collagen specifically our CollaGEM™-V that can be found in GLOW helps increase skin moisture levels and reduce transepidermal water loss, supporting plumper, more supple-looking skin and improved hydration from within.
- Biotin (Vitamin B7) acts as a crucial coenzyme for metabolism and plays a key role in maintaining the health of your hair, skin, and nervous system.
- Antioxidants protect skin from oxidative stress
- Vitamin C supports collagen formation
- Vitamin A supports skin cell turnover
- Hydration supports elasticity & vibrancy
It’s not about perfection, it’s about internal support.
A more holistic way to glow
Your skin reflects how nourished, rested and supported your body is. When we created Glow Kombucha, we wanted a formula that genuinely supports beauty from within, not a surface-level fix. The gut–skin axis is real, and when your insides are balanced, the outside follows.
