Lecithin is a naturally occurring phospholipid (commonly derived from soybean or egg) used in skincare as an emulsifier, emollient, and penetration enhancer. It helps stabilize oil-and-water formulations and supports the skin barrier by mimicking natural lipids.

Allergic contact dermatitis | Rare | Reported in individuals sensitized to soy- or egg-derived lecithin. |
