In this episode of The Healthspan Collective, host Nicole Doran sits down with Katie McKersie, holistic nutritionist and skin health specialist, to explore what is really driving acne and eczema and why the answer almost always starts in the gut. Katie brings a deeply personal perspective to this conversation, having navigated severe acne, hair loss, hormonal disruption, and a lost period after coming off the birth control pill herself, and has since built her practice around helping others find the root cause rather than the quick fix.
Katie breaks down the overlooked reality of post-birth control syndrome, explaining how the pill can quietly deplete key nutrients, disrupt gut bacteria, and throw hormones and thyroid function off balance long after discontinuation. She walks through the functional testing she uses with clients, the skincare reset that changed everything, and why healing the skin means healing the whole system first.
