Emollient

Quick Facts

Description: Emollients are substances that soften and soothe the skin. They help to moisturize dry, rough, or flaky skin, making it feel smoother and more supple.

Mechanism of Action: Emollients work by forming a protective layer on the surface of the skin. This layer helps to trap moisture, preventing water loss from the skin (reducing transepidermal water loss or TEWL). They also fill in the spaces between skin cells, creating a smoother surface. Emollients do not add moisture *to* the skin; they prevent the skin from *losing* moisture. Many emollients contain lipids (fats) that are similar to those found naturally in the skin.

Common Uses: Emollients are commonly used to treat and prevent dry skin conditions, such as eczema, psoriasis, and ichthyosis. They can also be used to soothe and protect chapped lips, cracked heels, and other areas of dry or irritated skin. Examples of herbs with emollient properties include Calendula, Marshmallow root, and Aloe Vera gel. Many vegetable oils (like olive oil, coconut oil, and almond oil) are also excellent emollients.
