Lecithin (Lecithin)

Lecithin is a naturally derived mixture of phospholipids (commonly sourced from soy or sunflower) used in cosmetic formulations as an emulsifier, skin-conditioning ingredient, and delivery-support component. Thanks to its phospholipid structure, it helps stabilize emulsions, improves spreadability, and contributes to a soft, supple after-feel that aligns well with barrier-supportive and biomimetic concepts. Lecithin is also frequently used to create liposomes or lamellar systems that can enhance the incorporation and sensory delivery of certain actives, while supporting a smoother, more cushioned texture. It is commonly found in facial and body creams, lotions, serums, cleansing emulsions, masks, and hair treatments, where it can improve feel, reduce dryness perception, and support overall formula elegance. Use level and performance depend on the lecithin grade (fluid, de-oiled, hydrogenated), phospholipid content, and processing method, and are typically optimized to balance stability, texture, and compatibility within the finished system.
