Lecithin

Description

Lecithin is a versatile phospholipid compound found naturally in various plant and animal tissues, with soybean and egg yolks being common sources. In skincare formulations, it serves multiple functions as an emollient, emulsifier, and penetration enhancer. Lecithin's molecular structure, consisting of both hydrophilic and lipophilic components, allows it to effectively bridge the gap between oil and water-based ingredients in cosmetic products.

This multifaceted ingredient helps improve skin barrier function by replenishing essential lipids and promoting moisture retention. Its emollient properties contribute to a smoother, more supple skin texture. As an emulsifier, lecithin stabilizes formulations, preventing separation of oil and water phases, which is crucial for product consistency and shelf life.

Lecithin also enhances the delivery of active ingredients deeper into the skin, potentially increasing their efficacy. Its ability to form liposomes—microscopic vesicles that can encapsulate other substances—makes it valuable in targeted delivery systems for various skincare actives.

While generally well-tolerated, individuals with soy allergies should exercise caution with soy-derived lecithin. Sunflower lecithin offers an alternative for those with sensitivities.
