Why the skin barrier matters in childhood eczema

In eczema, the skin barrier is weakened—moisture escapes, irritants get in, and skin becomes dry, itchy, and inflamed. Children’s skin is still developing, so it needs extra support, inside and out.

Codex Labs focuses on rebuilding and maintaining the skin barrier with a combination of topical eczema care and age specific L-histidine supplements designed for infants, toddlers, kids, and teens.

Why parents trust Codex Labs?

Parents trust Codex Labs because eczema-prone skin needs more than surface treatment—it requires addressing root causes like gut health, inflammation, and environmental triggers. We are also mindful that their microbiomes are still evolving so all of our products are certified microbiome-friendly.

At Codex Labs, our skin–gut–brain–biome approach goes beyond symptom relief to support long-term skin health from the inside out.

How our eczema systems work on the outside:

BIA ECZEMA RELIEF LOTION + BIA UNSCENTED SOAP

Strengthen the skin barrier

Strengthen the skin barrier
Emollients and ceramides help fill the “gaps” in the skin barrier, locking in moisture and blocking irritants. Hydrating humectants draw water into the skin, helping reduce dryness, tightness, and microcracks.BiaComplex helps rebuild the skin barrier by stimulating the natural production of key barrier proteins.

Rebalance the microbiome

Rebalance the microbiome
Our soap and lotion are designed to be microbiome-conscious, avoiding harsh preservatives or surfactants that can disrupt the skin ecosystem.By supporting the natural microbiome we can prevent unwanted inflammation and infection (like Staph).

Calm IRRITATION & itch

Calm IRRITATION & itch
Soothing, biotech plant-based actives and gentle dermatologic ingredients help: reduce visible redness, ease itch and stinging, support recovery after scratching and flares, shift microbiome from Staph

REBUILDING THE SKIN BARRIER FROM THE INSIDE
Supplements with L-histidine amino acid

L-histidine is an essential amino acid that plays a key role in forming structural protein filaggrin to support the outer skin layer and increasing natural moisturizing factors to retain hydration. By providing Lhistidine along with barrier-supportive vitamins and minerals, our supplements are designed to help maintain a stronger, more resilient skin barrier and support hydration and softness.

Each age group gets a tailored blend to meet their specific skin barrier needs:
Infants & Toddlers: L-histidine + zinc + skin vitamins + vitamin C
Kids: L-histidine + zinc + skin vitamins + vitamin D
Teens: L-histidine + M3 antioxidant
