  • Infants (3-12 mos): 1 sachet daily (30-day supply) = 1 carton/month
  • 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.

Each unflavored powder sachet contains amino acid L-Histidine (to build skin barrier protein filaggrin and natural moisturization factor) as well as key vitamins and minerals.

    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.
