Lecithin is a naturally occurring compound found in various foods, including egg yolks, soybeans, and sunflower seeds. Lecithin plays a vital role in biological systems, particularly in cell membranes. It acts as an essential building block for the phospholipid bilayer, which forms the structural framework of cell membranes. The amphiphilic nature of lecithin allows it to align and form a lipid barrier, regulating the passage of substances in and out of cells and maintaining cell integrity.
Benefits:
- Skin Barrier Enhancement: Lecithin serves as a fundamental component in the structure of cell membranes. In skincare, it reinforces the skin's natural barrier, supporting its integrity and resilience. This enhancement helps in moisture retention and protection against external aggressors, promoting hydrated and healthy-looking skin.
- Emollient and Moisturising Properties: With its emollient nature, Lecithin aids in softening and smoothing the skin's surface. Its moisturising properties assist in improving skin texture, leaving it feeling supple and hydrated.
- Antioxidant Defence: Lecithin contains phospholipids, which exhibit anti-oxidative properties. These antioxidants help neutralise free radicals, combating oxidative stress caused by environmental factors. This protection assists in preventing premature ageing and maintaining overall skin health.
- Penetration Enhancement: In skincare formulations, Lecithin acts as a natural emulsifier, enhancing the delivery of other beneficial ingredients into the skin. This property facilitates better absorption, improving the effectiveness of skincare products.
