Eczema-prone skin is not simply itchy, dry or sensitive. It is biologically different. Research shows that eczema is closely linked to a weakened skin barrier, where the structure that normally protects your skin becomes compromised. This allows moisture to escape while irritants, allergens, and microbes penetrate more easily, triggering visible redness, dryness, and discomfort.
At the center of this process is a critical protein called filaggrin. Filaggrin helps form the physical structure of your skin barrier and breaks down into natural moisturizing factors that maintain hydration and support a healthy skin pH. When filaggrin levels are low, the skin becomes more reactive and less resilient, which is why eczema-prone skin requires targeted, science-based care.
This collection is designed around a clinically informed, dual-action approach that supports eczema-prone skin from the outside and the inside.
Topical barrier-supporting skincare helps reinforce the outer layer of the skin by increasing filaggrin production. These formulations also focus on restoring hydration, supporting lipid balance, and helping maintain the skin’s natural microbiome. Ingredients such as plant-based oils, biotech-derived actives, and microbiome-friendly compounds help improve moisture retention, soothing itch, and fortifying the skin barrier, while calming visible signs of irritation.
Internal nutritional support, including targeted amino acids such as L-histidine, helps provide the building blocks your skin needs to produce filaggrin and maintain its natural moisturizing system. Research shows that histidine plays a key role in improving skin barrier function and supporting hydration from within.
Together, this inside-out strategy helps support long-term skin resilience rather than only addressing surface-level dryness.
Eczema can affect babies, children, and adults differently, but the underlying barrier dysfunction remains consistent. This collection includes targeted solutions for:
From gentle cleansers and unscented soaps to deeply nourishing creams, lotions, and facial oils, each product is formulated to respect the skin’s natural balance while minimizing disruption to the microbiome.
Healthy skin is not sterile. It is an ecosystem. The skin microbiome plays a critical role in maintaining barrier integrity, regulating inflammation, and protecting against harmful microbes.
Products in this collection are designed to be microbiome-supportive, meaning they help maintain a balanced environment where beneficial bacteria can thrive. This is essential for eczema-prone skin, where microbial imbalance by staphylococcus aureus is commonly observed.
Our formulations are developed with dermatologist insight and are clinically tested for sensitive skin. Many products meet rigorous safety and efficacy standards and are suitable for long-term use across age groups.
Trust is essential when choosing skincare for eczema-prone skin. This collection includes products that are:
Select products also carry recognized certifications such as the National Eczema Association Seal of Acceptance, reinforcing their suitability for sensitive and reactive skin types. All products are also certified Vegan and Cruelty-free.
Traditional skincare often focuses only on adding moisture and ceramides. However, eczema-prone skin requires more than hydration or lipids alone. It requires restoring the biological systems that keep skin functioning properly.
By combining:
This collection helps support the skin’s natural ability to maintain hydration, defend itself, and remain balanced over time.
Whether you are building a daily skincare routine or looking for a complete protocol that includes topical and internal support, this collection offers a comprehensive approach grounded in dermatological science.
Codex Labs is a unique blend of science and innovation that really works! It's my new go-to skincare line, both personally and for my acne patients.
I’ve always had red, inflamed, and bumpy skin. I have tried every product you can imagine, but the combination acne prone skin set from Codex has been the ONLY product to clear up my skin. My skin tone is even, I have no bumps at all, and even my pores look smaller! I’ve only been using it for 3 weeks, and my skin is already soft, smooth, and glowing. I really can’t recommend these products enough!
Codex Labs combines modern biotech and genetic science to create authentic skin care products focused specifically on the hydration of my skin while retaining moisture as well as soothing my sensitive skin.
My skin has never looked or felt better in my 50+ years, and I've used it ALL. I am currently undergoing chemotherapy and the Bia Superfood moisturizer and eye gel are both keeping my skin moisturized and soothed. To the point where I'm actually getting compliments on my skin during this treatment! Unheard of!
