Science

Lactis Proteinum operates by forming a protective barrier on the skin's surface, shielding it from external aggressors. Its comprehensive amino acid profile is crucial for maintaining optimal skin moisture levels and facilitating cellular regeneration. The bioactive components within milk proteins actively support skin cell renewal and fortify the natural skin barrier. It exhibits anti-irritant and protective properties, with specific constituents like lactoferrin potentially providing antimicrobial, antifungal, and antiviral activities that may benefit conditions such as acne and psoriasis. Glycomacropeptide further enhances the skin's lipid barrier and contributes to a balanced skin microbiota through its prebiotic effects. As a source of natural moisturizing factors (NMF), its amino acids bind water, improving skin volume, firmness, and resilience. Additionally, its peptide content offers a significant soothing effect on irritated skin.
