What is the function of essential fatty acids for skin health?

Essential fatty acids play a crucial role in maintaining the lipid barrier of the skin, which is vital for overall skin health. The lipid barrier is the outermost layer of the skin, composed of oils and fats that help retain moisture and protect against environmental irritants, allergens, and pathogens. Essential fatty acids, such as omega-3 and omega-6, are integral to the structure and function of this barrier. They help to keep the skin hydrated and prevent transepidermal water loss, which can lead to dryness and premature aging. By maintaining the integrity of the lipid barrier, essential fatty acids ensure that the skin remains supple and resilient. This is essential for optimal skin function and appearance.
