Most eczema treatments work on the surface. This protocol goes deeper. The BIA Infant Skin Barrier Supplement feeds filaggrin production with L-histidine, the amino acid your body needs to rebuild the skin barrier. BIA Eczema Relief Lotion calms itch, deeply hydrates, and promotes filaggrin production, while the Unscented Soap cleanses without stripping moisture or the microbiome.

SOOTHE ECZEMA WITHOUT STEROIDS BY REINFORCING SKIN INTEGRITY AND BOOSTING IMMUNITY WITH THE Eczema Relief Skin Barrier Protocol (Infant)

An impaired skin barrier allows particles from the external environment to penetrate the skin barrier and trigger inflammatory responses. In eczema, this inflammatory cascade is triggered by many factors, including allergens, irritants, and stress.  Inflammatory itch then triggers scratching, leading to further breakdown of the skin barrier. This cycles repeats itself in a loop of ever increasingly uncomfortable flares.

A strong skin barrier helps reduce itch and flares by:

  • stopping trans-epidermal water loss (parched skin) and not allowing allergens to penetrate (itch)
  • lowering inflammation/oxidative stress to reduce further skin and gut barrier (*and* collagen) degradation

The Skin Barrier dietary supplement helps:

  • produce more skin barrier proteins for structural support (filaggrin), and hydration (natural moisturization factor) with l-histidine.
  • address inflammation by scavenging free radicals produced by oxidative stress with anti-oxidants.

The Antü Skin Barrier Support Supplement contains a remarkable combination of ingredients to strengthen the skin barrier. The L-histidine alone has been shown to help heal damaged skin, but together with other anti-inflammatory and supportive botanicals make this a truly unique product. The lotion has also been studied in those with sensitive skin, and is packed with active botanicals designed for impaired skin.

The Antü Skin Barrier Support Supplement by Codex stands out with M3, a proprietary blend targeting skin resilience, and L-histidine, an amino acid that plays a critical role in repairing the barrier. Together, they help fortify the skin against environmental stressors while promoting a balanced, healthy complexion.
