The first eczema lotion accepted by the National Eczema Association and independently certified microbiome-safe. Steroid-free, fragrance-free, and safe for skin from three weeks old.
It usually starts around bedtime. The room is quiet, the lights are off, and then you hear it again: the soft, relentless sound of small fingernails dragging across skin. You have tried mittens. You have tried trimming the nails down to nothing. Some nights you lie awake just to catch the hand before it breaks the skin.
If you are the parent of a child with eczema, you already know the parts no one warns you about. The cracked patches behind the knees. The red, burning, peeling cheeks. The raw, weeping skin that gets infected. The comments at daycare and from family. And the quiet, constant worry that you are somehow doing it wrong.
You are not doing it wrong. The truth is that most of the options handed to parents are built to manage eczema, not to be trusted for daily, long-term use on a young child. That is the gap one scientist spent years trying to close.
By the time a parent goes looking for something new, the bathroom cabinet usually tells a familiar story:
The drugstore creams
They soothe for an hour, maybe a day, then the flare comes back exactly where it was.
The prescription steroid.
It works. That is the problem. You were told it is safe, and you still do not want your child on it every week for years.
The "clean" and "natural" brands.
Beautiful labels, gentle promises, and almost never any actual clinical proof. Some of them made the skin worse.
It is an impossible choice. The products with real clinical data tend to rely on the very preservatives and additives you are trying to avoid. The products marketed as clean rarely have the data to back up a single claim. One mother, a scientist, hit that exact wall, and refused to accept it.
The Turning Point
Dr. Barbara Paldus is not a beauty founder. She is a Stanford-trained scientist with more than fifty US patents, a background in laser physics, and a track record of building deep-technology companies long before she ever thought about skincare.
Then her infant son had a severe allergic reaction to phenoxyethanol, a preservative found in countless baby products. When she went looking for something clean enough to trust and proven enough to rely on, she discovered there was almost nothing in between. Clean brands lacked the clinical evidence. Clinically tested products used the ingredients that had hurt her son.
So she did what scientists do. She went into the lab and built the thing that should have existed already: a plant-biotech eczema system held to pharmaceutical standards, tested in clinical trials, and gentle enough for the most fragile skin in the house.
"I made this for my son first. Then I made it for everyone else's kid."
Dr. Barbara Paldus, Founder, Codex Labs
Most eczema creams do one job: add moisture and hope it holds. Bia was formulated to do three things at once, and it is built on an active complex that took years and four US patents to develop.
Biotech ferment that supports and protects the skin microbiome, the layer of good bacteria that standard cleansers and creams quietly strip away.
Ceramides rebuild the skin's natural lipid barrier so it holds moisture on its own. Hyaluronic acid rehydrates at the surface and below it.
A plant-biotech blend of Calendula, Comfrey, and Haberlea cellular extracts that work together to fortify the skin by supporting production of a protein called filaggrin.
An FDA-recognized over-the-counter active for the treatment of eczema. This is a pharmaceutical designation, not a marketing word. It relieves itch, calms redness, and balances skin pH.
It is the difference between calming a flare today and rebuilding the skin so the flares have less reason to come back.
OUTSIDE, MEET INSIDE
Eczema prone skin has a leaky barrier, which lets allergens in and triggers flares. That’s because a weak barrier is missing key structural proteins like filaggrin, the protein that keeps the barrier sealed and holds water in. The lotion helps rebuild the barrier from the outside by motivating the skin to make more filaggrin, but that process needs building blocks too. That is the inside half of the system.
Bia's Skin Barrier Support Supplements gives the body L-Histidine, the amino acid it uses to support filaggrin production and natural moisturizing factor. It is one of the only barrier-support supplements made for children's eczema in the US, in formats built for each age:
Unflavored powder for babies
Mixed-berry gummies for kids
Outside and inside, working on the same problem. As with any supplement for a child, check with your pediatrician first.
Parents of children with eczema have been burned by claims before. So Bia does not ask you to trust the brand. It asks you to trust the independent bodies that reviewed it.

From Parents Like You
Yes. Bia Eczema Relief Lotion contains colloidal oatmeal 1%, an FDA-recognized over-the-counter active, and is formulated for use on skin from three weeks old. It holds the National Eczema Association Seal of Acceptance, whose review includes formulation safety, and it is fragrance-free and steroid-free.
Bia is a steroid-free option for daily maintenance and mild-to-moderate flare management, and it is designed to reduce reliance on steroids over time. For severe flares or medically complex eczema, it is not a replacement for your pediatric dermatologist's plan. Always follow your doctor's guidance.
MyMicrobiome is an independent laboratory that tests products for their impact on the skin's microbial ecosystem. Certification means the lotion was verified not to disrupt the skin microbiome, a higher bar than self-declared "microbiome-friendly" claims.
Start with the lotion. It is a complete topical on its own and the simplest first step. Codex also makes an inside-out system: alongside the lotion, Skin Barrier Support gives the body L-Histidine, which it uses to support filaggrin production, the barrier protein that eczema-prone skin is often short on. It comes in child formats, an unflavored powder for infants and toddlers and mixed-berry gummies for kids 4 to 12.
Many parents report calmer, less itchy skin within the first two weeks, though every child is different. The clinical study measured results over eight weeks of consistent daily use.
