CASEIN

Description

Casein is a protein complex derived primarily from mammalian milk, most commonly cow's milk. This versatile ingredient has gained attention in the skincare industry for its potential benefits to skin health and appearance. Casein is composed of several phosphoproteins, including ��-casein, ��-casein, and ��-casein, which contribute to its unique properties.

In skincare formulations, casein functions as an emollient and moisturizer, helping to improve skin hydration and softness. Its ability to form a protective film on the skin surface aids in reducing transepidermal water loss. Casein also contains essential amino acids that may support skin barrier function and promote collagen synthesis.

Research suggests that casein possesses antioxidant properties, potentially protecting the skin from free radical damage and environmental stressors. Some studies indicate that casein peptides may have mild anti-inflammatory effects, making it a consideration for sensitive or irritated skin.

Formulators often incorporate casein into products such as moisturizers, serums, and masks. Its compatibility with various skin types and potential to enhance product texture make it a valuable ingredient in skincare formulations. However, individuals with milk allergies should exercise caution when using casein-containing products.
