The Preservative-Free Skincare Revolution with Dr. Rod Garcia, Medical Director of Skin at Peace

Follow us on instagram! @healthspancollective  In this episode of The Healthspan Collective, host Nicole Doran sits down with Dr. Rod Garcia, co-founder, formulator, and medical director of Skin at Peace, to challenge everything you think you know about clean skincare. Rod shares the origin story behind one of the most unconventional skincare brands on the market, a preservative-free, fresh-made subscription line that actually expires, built after watching his esthetician wife's skin react to products that were supposed to be good for her. Dr. Garcia brings a formulator's precision and a clinician's perspective to a conversation that cuts through the noise of the clean beauty world. He breaks down how preservatives disrupt the skin microbiome, why fragrance is one of the biggest red flags hiding in plain sight, and how chronic low-grade inflammation from everyday skincare could be the reason your skin never fully settles. From oil cleansing to vitamin C to barrier repair, this episode reframes what a truly supportive skincare routine actually looks like.

How to Heal Acne and Eczema From the Inside Out with Katie Mckersie

Follow us on Instagram! @healthspancollective 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. 🌿 What post-birth control syndrome actually is and how to recognize it 🧪 The functional tests worth doing before any protocol or supplement  🦠 How gut dysbiosis and leaky gut show up on your skin  ⚖️ Why restrictive diets and blind supplementation often make things worse  🧴 The caveman skincare method and how to reset your skin barrier  🩸 How stress, blood sugar, and seed oils are silently driving hormonal acne Chapters:  00:00 What Birth Control Could Be Doing to Your Body  02:13 Katie's Post-Pill Journey  05:04 How the Gut Microbiome Crashes  10:30 Understanding Post-Birth Control Syndrome  16:21 Why Testing Beats Guesswork  29:40 Minerals, PCOS, and Hormonal Acne  37:21 Food, Dairy, Gluten and What Actually Matters  46:35 Seed Oils, Supplements and Skin  52:50 Why Healing Takes Time  55:12 Caveman Skincare and Sun Exposure Connect with Katie McKersie! 🌐 www.holistico.ca [http://www.holistico.ca/] 🛍️ shopholistico.com [http://shopholistico.com/] 📱 @katiemckersie  📱 @shopholistico #TheHealthspanCollective #Podcast

Nicole Laino brings both depth and accessibility to a system that can feel overwhelming at first glance. She walks through the foundations of human design, sharing how it weaves together ancient wisdom and modern science, from the I Ching and Kabbalah to quantum physics and astrology, and why that synthesis makes it such a uniquely complete map of the self.

The Truth About Clean Beauty with Catherine Lockhart

Follow us on Instagram! @healthspancollective In this episode of The Healthspan Collective, host Nicole Doran sits down with Catherine Lockhart, clean beauty influencer, biohacker, and founder of Shelter Skin, to unpack why the wellness industry's most comforting labels are often its most misleading ones, and what it actually takes to build a truly low-tox life.  Catherine's journey began not in a lab, but in a Sephora aisle, surrounded by fragrance-heavy products she trusted completely. It wasn't until she came off birth control and began suspecting undiagnosed PCOS that she started questioning everything she was putting on her body. What followed was a deep dive into ingredient literacy, regulatory gaps, and the quiet ways everyday products can disrupt hormones, trigger brain fog, and undermine the very health we're trying to protect. She's since channeled that knowledge into Shelter Skin, a bootstrapped clean beauty brand formulated with naturals and scented with real vanilla bean infusion, built from conviction, not trend. What we cover in this episode: 🏷️ Why "clean," "non-toxic," and "naturally derived fragrance" are largely unregulated marketing terms and how to see through them  🌿 A practical low-tox roadmap: where to start, what to prioritize, and how to maintain an 80/20 balance in the real world  🧴 How to actually read a label, spot greenwashing, and understand the gap between U.S. and EU cosmetic regulation  👗 PFAs in activewear, natural fiber alternatives, and the hidden toxins in everyday textiles  💉 Wedding skin prep without Botox, exploring Sofwave, microneedling, EasyGel, and why Catherine skips injectables entirely  ✨ The story behind Shelter Skin, bootstrapping production, formulating with naturals, and scaling a clean beauty brand from the ground up Chapters:  00:00 The Wake-Up Call Nobody Talks About  00:52 Meet Catherine Lockhart  05:08 The Perfume Detox That Changed Everything  11:21 How to Actually Start a Low-Tox Life  15:07 Decoding Fragrance Claims and Greenwashing  19:09 U.S. vs. EU: The Regulation Gap  21:12 Living Low-Tox in the Real World  26:20 PFAs, Activewear, and What You're Wearing  41:19 Wedding Skin Without Botox  49:31 Building Shelter Skin from the Ground Up #TheHealthspanCollective #Podcast

Thyroid Truths, GLP-1s, and Why Women Are Still Being Gaslit with McCall McPherson

Follow us on Instagram: @thehealthspancollective In this episode of The Healthspan Collective, host Nicole Doran sits down with integrative thyroid expert McCall McPherson, founder of Modern Thyroid Clinic, for a conversation on thyroid dysfunction, women’s health, and why so many women are still being told their labs are “normal” while continuing to feel unwell. McCall shares her own experience struggling with debilitating hypothyroid symptoms despite being prescribed standard thyroid medication, and how that journey ultimately led her to specialize in thyroid care. Together, Nicole and McCall unpack the limitations of conventional thyroid testing, including why relying on TSH alone can leave many women undiagnosed or improperly treated. The conversation explores the importance of full thyroid panels, the role of T3-containing medications, and the symptoms that are often overlooked or dismissed, from low libido and dry skin to puffiness, fatigue, thinning eyebrows, and inability to sweat. They also discuss Hashimoto’s disease, thyroid autoimmunity, and the growing links between COVID, long COVID, and thyroid dysfunction. Nicole and McCall also get into fertility, miscarriage prevention, postpartum thyroid shifts, menopause, hormone replacement therapy, and the nuanced conversation around GLP-1s. McCall explains her approach to microdosing GLP-1 medications for inflammation, metabolic dysfunction, and weight management, while emphasizing patient safety and individualized care. This episode is a deeper look at the intersection of thyroid health, hormones, metabolism, and advocacy, especially for women who know something feels off despite being told everything looks “fine.” What We Cover: * Why normal thyroid labs don’t always mean optimal health * The limitations of testing TSH alone * T3, Armour, Cytomel, and thyroid medication differences * Common overlooked thyroid symptoms * Hashimoto’s testing and thyroid autoimmunity * COVID and long COVID thyroid connections * Graves’ disease explained * Fertility, miscarriage, and postpartum thyroid health * Menopause, HRT, and hormone shifts * GLP-1s, inflammation, and metabolic health Chapters: 00:00 ⚠️ The T3 Pregnancy Debate 02:19 🧠 McCall’s Thyroid Wake-Up Call 05:56 💊 Synthroid vs Armour 09:00 🔬 The TSH Testing Problem 13:54 🚩 Overlooked Thyroid Symptoms 15:55 🦋 Hashimoto’s and Antibody Testing 18:27 🦠 Long COVID and Thyroid Links 27:17 📉 GLP-1 Myths and Benefits 44:23 🌡️ Menopause and Thyroid Autoimmunity 50:33 🤍 Fertility, Miscarriage and Thyroid Health
