Your gut and your skin
are connected.
Researchers call it the 'gut-skin axis', a bidirectional relationship where your gut microbiome directly influences skin inflammation and acne. Studies published in Gut Microbes show that gut dysbiosis can trigger immune responses that manifest as breakouts. What you eat shapes both.

The gut-skin axis is real
Research published in Gut Microbes confirmed a bidirectional relationship between gut and skin health. When gut microbial communities are disrupted, the immune response can trigger skin inflammation, including acne vulgaris.
Diet drives the connection
A diet high in sugar, saturated fats, and low in omega-3 fatty acids worsens acne by causing gut dysbiosis, increasing insulin and IGF-1 levels, and stimulating sebum production and inflammation. Tracking diet helps you identify which foods disrupt your system.
Track food and skin together
ClearSkin logs your daily diet alongside your skin condition. Over weeks, patterns emerge, certain foods may consistently precede breakouts, while others correlate with clearer skin.
Measure the impact of changes
Added probiotics or fermented foods? Cut processed food? ClearSkin shows you whether these changes actually improve your skin with clear before-and-after timelines.
Frequently asked questions
How does gut health affect acne?
Your gut microbiome communicates with your skin through immune signalling, hormones, and metabolites. When gut bacteria are imbalanced (dysbiosis), it can trigger systemic inflammation that manifests as acne. Research in Gut Microbes has shown this is a two-way relationship, skin conditions can also affect gut health.
Can probiotics help with acne?
Emerging research is promising. Studies have found that certain probiotic strains, including Lactobacillus and Staphylococcus epidermidis, may help reduce acne by modulating gut dysbiosis and reducing inflammatory markers. However, results vary by individual, which is why tracking your response to dietary changes is more useful than following generic recommendations.
What foods support the gut-skin connection?
Research suggests that diets rich in fibre, fermented foods (yoghurt, kimchi, sauerkraut), omega-3 fatty acids, and low in processed sugar and saturated fats support a healthy gut microbiome. These same dietary patterns are associated with reduced acne severity in multiple studies. Tracking your specific diet helps you find what works for your body.
