Marli Ollerton – My Story

In my teenage years, I never gave much thought to my skin. I was fortunate to have clear, problem-free skin and rarely experienced any concerns.

But as I entered my mid to late 20s, everything changed. By that stage, I was almost on a journey with irritable bowel syndrome (IBS), which had been triggered by continuous antibiotic use. Not only was I dealing with severe bloating, digestive discomfort, and fatigue, but my skin had also become a major concern.

I had also come off hormonal contraception and experienced what is commonly referred to as “rebound acne”, a flare-up of acne that can occur as the body readjusts to producing and regulating its own hormones. Acne, redness, and inflammation started to appear a lot more intensely, and I thought it would naturally calm down once my hormones regulated.

I used different topical creams, cleansers and exfoliants to manage it. However, every time my skin started to clear up, more redness, cysts and pimples would appear, and it got to the point where it was really impacting my confidence.

I later found out IBS is diagnosed when there is no “known” cause for your symptoms and everything else has been ruled out. My GP had ruled out coeliac disease and parasite infections, then suggested a colonoscopy due to my family history of bowel cancer, which was extremely daunting for a young woman to hear. I was then referred to a gastroenterologist who told me that it was probably just lactose intolerance.

My GP then suggested for me to work on reducing stress because the nervous system can be connected to digestion. At this point I was starting to feel defeated.

Through my training and clinical experience, I developed a much deeper understanding of the microbiome and its far-reaching impact on not only digestive health, but also hormones, mood, energy levels, immune function, and skin health.

When I undertook comprehensive gut testing, I discovered that one of the key contributors to my symptoms was actually a lack of microbiome diversity (which isn’t tested in most medical settings). A diverse and rich microbiome plays a critical role in nutrient absorption, immune regulation, inflammation control, and the body’s natural detoxification processes.

In my case, the problem wasn’t just that I was stressed or eating too much dairy, but that my whole gastrointestinal tract’s microbiome was starved, preventing it from doing what it was supposed to do, and therefore leading to all the IBS symptoms I had been experiencing for years.

No amount of expensive skincare could address the root cause because the issue was coming from within. We have been brought up to believe that all bacteria is bad, but think of it this way: in a pot of soil, you need bacteria, insects, pollinators and nutrients for plants to thrive. When those are absent, its fruit might taste sour, perhaps the leaves turn brown or the whole plant just dies. Our microbiome is the same.

By focusing on rebuilding my gut health and replenishing the beneficial bacteria, I began to see significant improvements not only in my digestion and energy, but also in my skin. The redness subsided, breakouts became less frequent, my hormones and period regulated, and my confidence gradually returned.

Natural medicine not only transformed my skin but also gave me the tools to take control of my health. Now I feel more confident than ever and am passionate about helping others explore the powerful connection between gut health, hormonal balance, and vibrant skin.
