“We were desperate as she was clawing her head all the time. Now we can all sleep and not worry.”

— Francis

Aneta

“After incorporating these products into my daily routine, I noticed an overall improvement in my skin condition within the first few weeks. The dryness decreased, and the uncomfortable feeling of tightness was significantly reduced. I believe that the combination of supporting my skin both from the inside and the outside has been extremely beneficial for me. It felt like the missing piece of the puzzle in my eczema treatment.”

— Aneta

Kristina

“I can honestly say that the quality of my skin is incomparable to what it was before. Of course, a complex condition like atopic dermatitis cannot be solved with a single supplement, but I have noticed significant improvements in my skin quality—it is less dry and flaky, it no longer burns, the itching has decreased, and my skin is much less reactive.”

— Kristina

FAQs

Questions, Answered

Codex Labs products are not steroids and do not contain corticosteroids. Instead, they are formulated with clinically studied botanical ingredients and skin-supporting compounds designed to help support the skin barrier, soothe irritation, and promote healthier-looking skin. While topical steroids work by suppressing inflammation and are often used for short-term symptom management, Codex Labs products are designed to support long-term skin health and resilience through daily skincare.

Yes. Many Codex Labs products are formulated with sensitive skin in mind and are designed to be gentle enough for both children and adults. The company also offers products specifically developed for children, including its BIA Kids line for children ages 4 and older. Codex Labs emphasizes microbiome-friendly, dermatologist-tested formulations and provides age-specific recommendations for certain products.

Because every child’s skin is unique, we recommend reviewing the age guidance and usage instructions on each product page. If your child has a medical condition, severe skin concerns, or known allergies, consult your pediatrician or dermatologist before use.

The Codex Labs Inside & Out Protocol is a comprehensive approach that combines targeted dietary supplements with topical skincare to support skin health from both within the body and on the skin's surface. The protocol is based on the connection between the skin barrier, gut health, oxidative stress, and the microbiome..

How fast will I see results?

In clinical studies, participants experienced significant improvements after 8 weeks of consistent use. Some people may notice benefits sooner, depending on their individual skin condition and overall health. While results can vary, clinical trials showed improvement among all participants who completed the study.

Because eczema is a complex condition influenced by factors such as skin barrier function, gut health, environment, diet, and stress, the timeline and degree of improvement may differ from person to person. Consistent daily use of the recommended products is important for achieving the best results.

If you have been using your system consistently for 8 weeks or longer and feel you need additional support, consider speaking with your healthcare provider or exploring complementary products within the Codex Labs eczema support protocols.

Many Codex Labs products may be eligible for reimbursement through a Health Savings Account (HSA) or Flexible Spending Account (FSA), depending on your plan's rules and the specific product purchased. Eligibility can vary by provider, product category, and whether a healthcare provider's recommendation or prescription is required.

We recommend checking with your HSA/FSA administrator before purchasing or submitting a claim. Be sure to save your receipt and any supporting documentation, as reimbursement requirements may vary by plan.

Codex Labs cannot guarantee HSA/FSA eligibility or reimbursement, and customers are responsible for confirming coverage with their benefits provider.

What if the products don’t work for me?

Everyone’s skin is different, and results can vary depending on factors such as skin barrier health, gut health, lifestyle, environmental triggers, and the severity of symptoms. While clinical studies showed significant improvement with consistent use, some individuals may require additional support or a different combination of products to achieve their desired results.

If you have been using your Codex Labs products consistently for 8 weeks or more and are not seeing the results you expected, you may benefit from expanding your approach. For example, some people respond best to skin barrier support, others to gut barrier support, and some may need both.

If you have questions about your progress, our customer care team can help guide you toward the products that may best fit your needs. For persistent or severe symptoms, we recommend consulting a healthcare professional, as eczema is a chronic, multifactorial condition that may require a personalized treatment plan.
