  • Toddlers (1-3 yrs): 2 sachets daily (15-day supply) = 2 cartons/month

A daily infant-toddler (3 months -3 years) dietary supplement that fortifies the skin barrier to reduce water loss, smooth roughness, and protect against flare-ups from allergens and pollution. A healthy skin barrier means less skin sensitivity and de-hydration.

Build a Stronger Skin Barrier with Eczema Relief Skin Barrier Supplement (3m-3y)

We know that classic eczema (atopic dermatitis), is a chronic skin condition where the skin barrier is weakened or disrupted. This can lead to a cycle of inflammation, redness, and itchiness. Scratching further weakens the skin barrier, which can worsen the condition and lead to infections.

The filaggrin gene (filament aggregating protein) plays an important role in maintaining skin barrier integrity, preventing de-hydration, as well as preventing pathogens and irritants from getting through the skin barrier.  Those with eczema may have fewer copies of the FLG gene, resulting in less functional filaggrin protein in the epidermis, less natural moisturization factor, and a leakier skin barrier. [image reference: DOI 10.1111/bjd.14997] This in turn increases water loss (skin de-hydration) and pH, inhibiting lipid-generating enzymes, which decreases skin cell adhesion (tight junctions/corneodesmosomes), deregulates skin turnover (desquamation), and decreases ceramides (the lipid matrix).

    Plant-Based

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.
