Coconut oil can be used as a moisturizer, but it is best used over a moisturizer or on damp skin. Coconut oil acts as a sealant, trapping water into the skin to keep it moist. It contains fatty acids, including lauric acid, which can be beneficial in maintaining healthy skin. Coconut oil also has emollient properties that can have a positive impact on dermatitis and mild to moderate xerosis, or extremely dry skin. Linoleic acid, another acid present in coconut oil, works to prevent moisture loss and helps trap water in the skin. Coconut oil can also help reduce inflammation associated with skin conditions because it contains no harsh additives or chemicals.
However, it is important to note that coconut oil is high in saturated fat, which can raise LDL (bad) cholesterol and increase the risk of cardiovascular disease and stroke when consumed. When using coconut oil as a moisturizer, it is important to look for coconut oil that is nonhydrogenated, cold-pressed or expeller-pressed, organic, and food-grade to avoid any unwanted ingredients.
In summary, coconut oil can be a good moisturizer for the skin, but it is best used over a moisturizer or on damp skin. It contains fatty acids and emollient properties that can help maintain healthy skin and reduce inflammation associated with skin conditions. However, it is important to use it in moderation and to look for high-quality coconut oil to avoid any unwanted ingredients.
