If you're struggling with dry, irritated, or eczema-prone skin, you're not alone. Millions of people deal with these skin challenges every day, affecting not just comfort but confidence. The good news? Nature has powerful remedies. And one of the most promising is Coix Seed extract that can be topical or ingested as a beauty from within supplement.
In this post, we'll explore how Coix Seed, a traditional Japanese ingredient found in Crane Wellness' Tone & Glow powder, can help hydrate the skin and relieve eczema symptoms. I've recommended to loved ones with eczema and they've seen some pretty amazing results - with one (who is also a medical professional) say "where has this been all my life?". Let's take a look at additional natural remedies, research-backed benefits, and what you can do to support healthier skin from the inside out.
What Is Coix Seed?
Also known as Job's Tears or Hatomugi in Japan, Coix Seed (scientific name: Coix lacryma-jobi) is a gluten-free ancient grain native to East Asia. Traditionally used in Chinese and Japanese medicine, Coix Seed has been prized for centuries for its anti-inflammatory, skin-brightening, and immune-boosting properties.
Unlike many modern extracts that rely on harsh chemicals, Tone & Glow uses a patented extraction method with just water and enzymes, ensuring purity and potency. This concentrated powder can even be used topically as a skin mask—making it both an internal and external beauty ally.
1. Hydrates Skin from Within
Healthy skin starts with hydration. Coix Seed contains natural polysaccharides, which help retain moisture in skin cells. In a 2021 study published in the Journal of Ethnopharmacology, Coix Seed extract was shown to significantly increase skin hydration and reduce trans-epidermal water loss (TEWL), one of the root causes of dry, flaky skin.
Ingesting Coix Seed daily (as found in Tone & Glow) supports your skin barrier from the inside—nourishing cells and promoting a smoother, dewier complexion.
2. Reduces Inflammation Linked to Eczema
Eczema is often fueled by chronic inflammation in the skin. Coix Seed contains coixenolide, a powerful bioactive compound known for its anti-inflammatory properties. A study published in Bioscience, Biotechnology, and Biochemistry found that coixenolide suppresses the release of pro-inflammatory cytokines, reducing skin irritation and flare-ups.
This makes Coix Seed especially helpful for individuals experiencing red, itchy, and painful eczema symptoms.
3. Supports Gut-Skin Connection
Recent science highlights the close relationship between gut health and skin conditions like eczema. Coix Seed is rich in prebiotic fibers, which feed the beneficial bacteria in your gut and help improve overall digestion and immune response.
A balanced gut microbiome plays a crucial role in regulating inflammation and can reduce the likelihood and severity of eczema outbreaks.
4. Fights Bacterial and Fungal Irritants
Many people with eczema are more prone to bacterial or fungal skin infections. Coix Seed has natural antibacterial and antifungal properties, helping your body defend against these skin stressors. In lab studies, Coix Seed extract showed strong inhibition of pathogens like Staphylococcus aureus, which commonly affects eczema-prone skin.
5. Promotes Skin Cell Turnover
Dull and dry skin can result from sluggish skin cell turnover. The amino acids and antioxidants in Coix Seed encourage healthy regeneration of skin cells, which is essential for healing damaged skin and fading discoloration left behind from flare-ups.
Additional Natural Remedies for Eczema Relief
While Coix Seed is a powerful tool, a comprehensive approach to eczema can provide even better results. Here are a few science-backed additions:
-
Omega-3 Fatty Acids: Found in flaxseeds, walnuts, and algae-based supplements, omega-3s reduce inflammation and support skin integrity.
-
Probiotics: Especially Lactobacillus rhamnosus, which has been shown in studies to reduce eczema severity in children and adults.
-
Vitamin D: Low vitamin D levels are often linked with eczema. Ask your doctor about supplementation.
-
Colloidal Oatmeal Baths: Provide soothing relief for inflamed skin and reduce itching.
-
Stress Reduction Techniques: Stress is a major eczema trigger. Practices like mindfulness, meditation, and gentle movement can help reduce flare-ups.
Topical Coix Seed Mask for Eczema-Prone Skin
Did you know Tone & Glow can also be applied directly to the skin? Here’s a simple mask recipe:
DIY Coix Seed Skin Mask:
-
Mix 1 teaspoon of Tone & Glow powder with a few drops of water until a paste forms
-
Apply gently to clean skin (target dry or irritated areas)
-
Leave on for 20 minutes or until fully dry and flaky
-
Rinse with lukewarm water and apply moisturizer
Many users report softer, calmer skin and less redness after one use and drastic improvements after regular weekly use.
A Note of Caution
While Coix Seed is safe for most people, it should not be consumed during pregnancy, as it may stimulate the uterus. Always consult your healthcare provider before starting any new supplement, especially if you have underlying health conditions.
Final Thoughts
Eczema can be frustrating, painful, and emotionally draining—but with the right tools, you can support your skin naturally and effectively. Coix Seed offers a unique blend of hydration, anti-inflammatory action, and skin-nourishing nutrients that work from the inside out.
Whether you're sipping on a morning scoop of Tone & Glow or applying it as a mask, you're giving your skin the natural support it deserves.
