Understanding the Real Causes Behind Skin Conditions: Insights from Dr. Dasha Leneva

In this insightful episode of The Tonic, naturopathic doctor Dr. Dasha Leneva joins host Jamie to bust popular skincare myths and share evidence-based strategies for managing skin conditions like acne, eczema, and psoriasis. This must-listen conversation blends naturopathic insight with practical advice for anyone seeking healthier skin from the inside out.

🔍 Is drinking more water the key to glowing skin?

Dr. Leneva addresses this persistent myth by citing research that shows hydration does help reduce trans-epidermal water loss but has minimal effect on acne and eczema. These benefits do tend to tap out at approximately 2 litres per day. While staying hydrated is important, overhydration won't be your miracle cure. She emphasizes that skin reflects internal health, and treating symptoms externally isn't enough without addressing underlying causes.

👩‍⚕️ Beyond Teen Acne: The Role of Hormones and Stress

Think acne is just a teenage issue? Think again. Dr. Leneva highlights that over 50% of adult women and 40% of adult men still suffer from breakouts well past the age of 25. The culprits? Often chronic stress, insulin resistance, and hormonal imbalances. She explains how high androgen levels (like testosterone and DHT) are tied to adult acne, and how identifying hormonal triggers is instrumental for long-term skin clarity.

🌿 Managing Eczema and Psoriasis Naturally

From vitamin D3 to omega-3s and targeted probiotics, Dr. Leneva discusses the multifactorial nature of eczema and psoriasis. While these conditions may have a genetic component (such as a filaggrin gene deficiency) which disrupts the skin barrier, she shares a hopeful message: symptoms can be managed effectively with the right combination of gut health, moisturization, and lifestyle changes. She stresses timing moisturization following a shower as a wise protocol. Even cold plunges and saltwater treatments, trending on social media, have their place—but only for the right skin types. Dasha shares how salt water may help some skin conditions but the lowering of stress during a seaside vacation likely plays a part. They also touch on the effects of chlorine as an irritant.

🧘 Skin and Stress: A Two-Way Street

Dr. Leneva makes a powerful case for the mind-skin connection. Stress hormones like cortisol increase oil production, break down the skin barrier, and trigger inflammation. But she doesn't stop at the science—she offers actionable tools like cognitive behavioral therapy (CBT), mindfulness, and adaptogenic herbs (magnesium, valerian, passionflower) to help patients manage emotional triggers which can manifest physically on their skin.

🔥 Saunas, Sea Salt & Skin Detox – What Works and What Doesn’t

Do saunas actually “detox” your skin? What about infrared vs. traditional heat? Dr. Leneva explains how excessive sweating can sometimes make acne worse and how saunas can flare sensitive conditions like eczema and rosacea. Sea salt treatments like Dead Sea soaks may soothe mild eczema but aren’t cures. Ultimately, balance and consistency are better long term than extremes.

🧴 Minimalism in Skincare

Her final take-home truth? You don't need a 12-step skincare routine. Overdoing it can damage your skin. Instead, focus on simple, targeted routines backed by science—and always listen to what your skin is trying to communicate. "Your skin isn’t betraying you," she says. "It’s giving you clues—learn to decode them." Hopefully, these tips will help you decode your particular situation so you can address the cause and not merely the symptoms of your skin concerns.

Whether you're struggling with skin conditions or simply overwhelmed by conflicting advice, this episode offers clarity, compassion, and holistic strategies to help you glow from the inside and out.
