Skin & hair health

Skin and hair reflect the body's nutritional status. Deficiencies in zinc, biotin, vitamin C, silicon or essential fatty acids produce documented cutaneous and hair signs. This section explores established links between nutrition, micronutrition and dermatological health: collagen synthesis mechanisms, the hair cycle, skin barrier integrity, and the microbiome's influence on skin. Content draws on dermatological studies and clinical trials, with close attention to the EC 1924/2006 regulatory framework.
