Fatty Acids for our Skin


Fatty acids are organic compounds that play a crucial role in various physiological processes within the human body. These compounds are not only essential for maintaining overall health but also exhibit significant benefits for the skin. In this article, we will explore what fatty acids are, how they benefit the skin, and the best topical applications of fatty acids for optimal skin health.


Fatty acids are long chains of hydrocarbon molecules with a carboxyl group (-COOH) at one end [1]. They can be classified into three categories based on their saturation levels: saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and polyunsaturated fatty acids (PUFAs). Each type of fatty acid has distinct properties and impacts on the body [2]. SFAs are solid at room temperature and are usually animal derived with the exception of palm oil and coconut oil. Plant and seed oils are typically high in PUFAs.


  1. Moisturization and Hydration: Fatty acids act as natural moisturizers by forming a protective barrier on the skin's surface, preventing moisture loss and maintaining hydration levels. They help strengthen the skin's natural lipid barrier, keeping it supple, soft, and preventing dryness.
  2. Anti-Inflammatory Properties: PUFAs, particularly Omega-3 and Omega-6 fatty acids, possess potent anti-inflammatory propertiesThese fatty acids help reduce inflammation and calm various skin conditions, such as acne, eczema, and psoriasis. By suppressing inflammation, they promote a healthier and more balanced complexion.
  3. Skin Barrier Function: The skin barrier is responsible for protecting the skin against external aggressors and maintaining its integrity. Fatty acids contribute to the formation of the skin barrier by improving the intercellular lipids, which help retain moisture and protect the skin from environmental damage.
  4. Prevent Skin Damage: Certain fatty acids, such as linoleic acid (a PUFA), exhibit antioxidant properties that help combat oxidative stress caused by free radicals. By neutralizing these harmful molecules, fatty acids help prevent premature skin aging, reduce the appearance of fine lines and wrinkles, and promote a youthful complexion.


  1. Facial Oils: Facial oils infused with fatty acids, such as argan oil, rosehip oil, or jojoba oil, can provide intense hydration and nourishment to the skin. These oils are easily absorbed and can be applied directly to the skin or mixed with moisturizers to enhance their effectiveness.
  2. Emollient Creams: Emollient creams containing fatty acids are especially beneficial for individuals with dry, sensitive, or eczema-prone skin. These creams work by forming a protective film on the skin's surface, preventing moisture loss and soothing irritations.
  3. Omega-3 and Omega-6 Supplements: While topical application is effective, incorporating fatty acids into your diet can also have a positive impact on the skin. Omega-3 and Omega-6 supplements, such as fish oil or flaxseed oil capsules, can enhance skin health from within, providing a holistic approach to skincare.
  4. Body Lotions and Butters: Body lotions and butters enriched with fatty acids help maintain the skin's moisture balance and prevent dryness. Look for products containing shea butter, cocoa butter, or coconut oil for optimal nourishment and hydration.


Fatty acids are essential for maintaining the overall health of our bodies, including our skin. Their moisturizing, anti-inflammatory, and anti-aging properties make them a valuable addition to skincare routines. Whether applied topically through facial oils, emollient creams, or body lotions, or consumed through dietary supplements, fatty acids provide numerous benefits for the skin. By incorporating these powerful compounds into our skincare regimens, we can achieve healthier, hydrated, and radiant skin.
