Emollient
Definition
An emollient is a type of moisturizing ingredient or product that works by filling in the gaps between skin cells with lipids, creating a smoother, softer skin surface. Unlike humectants (which attract water) and occlusives (which seal moisture in), emollients specifically improve skin texture and flexibility by repairing the spaces in a compromised skin barrier. Common emollient ingredients include ceramides, squalane, fatty alcohols (cetyl and cetearyl alcohol), shea butter, and plant oils like jojoba and rosehip oil. Emollients are a cornerstone of treatment for dry skin conditions, eczema, and barrier repair. They can be found in various product formats including creams, lotions, ointments, and oils. For best results, emollients should be applied to damp skin to help trap existing moisture.
