Using Fatty Acids for Dry Skin

Dry skin often stems from a compromised barrier, leading to increased transepidermal water loss. Topical application of fatty acids mimics the natural lipids present in the stratum corneum, which helps maintain the structural integrity of the skin surface.

This practice does not change skin type but serves as a functional maintenance method. The goal is to provide a physical occlusive layer that limits moisture evaporation throughout the day and night.

1. Cleanse the surface. Use a water-based cleanser to remove surface debris and pollutants. Do not use hot water, as it can strip the skin of existing oils. Pat the face dry with a clean, lint-free towel until the skin feels slightly damp to the touch.
2. Apply humectants. Before applying fatty acids, introduce a humectant such as glycerin or hyaluronic acid. This provides the necessary water content for the skin. Allow the product to absorb for one minute without fully drying.
3. Layer the fatty acids. Dispense three to four drops of a lipid-rich oil or cream containing linoleic or oleic acid into your palms. Press the product firmly into the skin, starting at the cheeks and moving toward the perimeter of the face. Avoid dragging the skin.
4. Seal with a final layer. If necessary, apply a lightweight occlusive cream to lock in the previous steps. This ensures the fatty acids remain concentrated on the surface rather than dissipating. Verify that the product has settled into a soft, non-tacky finish.

Lipids function as the mortar between the bricks of your skin barrier.
