Episode 105: Eczema, Psoriasis & Rosacea: Differences & Skin Health Solutions with Dr Angela Tewari
Have you struggled with unexplained redness, irritation, flare-ups, or changes in your skin as an adult? In this episode, dermatologist Dr Angela Tewari breaks down the real differences between eczema, psoriasis, and rosacea. How each condition works beneath the surface, why they show up differently, and what they reveal about your overall skin health. You’ll learn what defines a truly healthy skin barrier, the early signs of imbalance, and why chronic skin conditions are becoming increasingly common in our 30s, 40s, and 50s.
We also explore the powerful connection between your skin, immune system, gut health, stress, and lifestyle, because real healing requires more than topical treatments. Dr Tewari explains the genetic and immune pathways behind these conditions, the role of the microbiome, and the most common triggers she sees in clinic, including stress, environmental toxins, irritants, hormones, and dietary factors. You’ll walk away understanding not just what your skin is doing, but why it’s doing it.
This episode answers questions like:
“What is the difference between eczema, psoriasis, and rosacea?”
“Why do adults suddenly develop eczema or rosacea?”
“Can stress cause eczema or psoriasis flare-ups?”
“What are the early signs of an unhealthy skin barrier?”
“How does the gut affect skin health?”
“What supplements help eczema or psoriasis?”
“What is the best skincare for sensitive or inflamed skin?”
Finally, we dive into practical and evidence-based solutions you can start implementing today. From dermatology-approved treatments to holistic tools like ceramides, probiotics, vitamin D, omega-3s, anti-inflammatory nutrition, and gentle skincare routines, this episode gives you a realistic roadmap for reducing flare-ups and rebuilding a resilient skin barrier. If you want to understand your skin at a deeper level and feel more confident in supporting it, this episode will change the way you approach skin health.

“What is healthy skin? AI tells me it’s hydrated, shiny, baby soft skin, even toned, no pores, no pigmentation. But depending on the age bracket of the person you ask, it’s to do with happiness, a glow, which is probably more coming from within. I’d say healthy skin is happy skin. And that happiness probably radiates from within. The sun shines out of your eyes. When you crinkle, when you smile, and the sun shines from your eyes, I think those are important points to bear in mind first of all.”

Eczema, psoriasis, and rosacea: these chronic inflammatory skin conditions differ in their causes, immune pathways, symptoms, and long-term management.
Adult skin issues are more common than ever. From chronic stress and gut imbalances to environmental toxins and epigenetic changes.
Healthy skin is less about “perfect pores” and more about a resilient skin barrier, balanced microbiome, and signs of internal harmony.
Stress hormones, sleep, nutrition, the gut microbiome, vitamin D, and omega-3s all influence inflammation and the skin barrier.
