Hey BB gang! 🌟 Today, I'm looking into the world of fatty acids and their transformative benefits in skincare. Sure, we've all been told many times to take cod liver oil for various concerns but how much have you really looked into the science behind the cod liver oil, and whether there are better options more suited to your skincare? Well you'll be pleased to hear there are many fatty acids skincare options available now! I'll go through the science behind these essential compounds, their roles in maintaining skin health, and the top products that harness their power. Get ready to glow like never before!
What Are Fatty Acids?
Fatty acids are essential components of lipids, which are vital for maintaining the integrity and function of our skin’s barrier. They are organic molecules made up of carbon, hydrogen, and oxygen atoms, and they play a crucial role in various bodily functions. Fatty acids are categorized based on the presence and number of double bonds in their carbon chains: saturated, monounsaturated, and polyunsaturated fatty acids.
The Science Behind Fatty Acids
Saturated Fatty Acids: These have no double bonds between carbon atoms, making them stable and solid at room temperature. They are excellent for forming a protective barrier on the skin’s surface, locking in moisture and protecting against irritants.
Examples:Â Lauric acid (found in coconut oil), stearic acid (found in shea butter), and palmitic acid (found in palm oil).
Monounsaturated Fatty Acids:Â These contain one double bond, making them more fluid than saturated fats. They help improve skin elasticity and provide anti-inflammatory properties, beneficial for sensitive and acne-prone skin.
Examples:Â Oleic acid (found in olive oil), palmitoleic acid (found in macadamia nut oil), and vaccenic acid (found in sea buckthorn oil).
Polyunsaturated Fatty Acids: These have multiple double bonds, making them highly flexible and fluid. They are essential for maintaining the skin’s barrier function, reducing inflammation, and providing deep hydration.
Examples:Â Linoleic acid (found in sunflower oil), alpha-linolenic acid (ALA, found in flaxseed oil), and gamma-linolenic acid (GLA, found in evening primrose oil).
The New Superstar: C15:0 Fatty Acid
What is C15:0?
C15:0, also known as pentadecanoic acid, is a newly discovered fatty acid that is making waves in the skincare and biohacking communities. As an essential fatty acid, C15:0 is critical for our bodies as it actively repairs, restores and revitalizes our long-term health at the cellular level. This odd-chain saturated fatty acid is found in trace amounts in some animal fats and full-fat dairy products - another reason to choose grass fed butter as your spread/oil replacement!
C15:0 is a robust and stable fatty acid that fortifies our cell membranes, ensuring our cells stay healthy. When cell membranes lack adequate levels of C15:0, they become fragile, leading to a newly recognized form of cell death known as ferroptosis.
Consequently, a deficiency in nutritional C15:0 can accelerate aging and impair metabolic, heart, and liver health. This condition is termed Cellular Fragility Syndrome. Research indicates that Cellular Fragility Syndrome may affect as many as 1 in 3 people worldwide. This article shows interesting research into C15:0 deficiency and tests to monitor your own levels at home.
How C15:0 is Revolutionizing Skincare
Scientific Breakdown:Â Unlike other saturated fatty acids, C15:0 has been shown to have unique health benefits, including anti-inflammatory properties and the ability to support cellular function.
Benefits in Skincare: C15:0 helps strengthen the skin’s barrier, reduce inflammation, and provide long-lasting hydration. Its unique structure allows it to integrate seamlessly into the skin’s lipid matrix, enhancing overall skin health.
I am currently trialling Fatty 15, the C15:0 supplement, and will report back on results in a couple of months. Hopefully I'll see the same great results as others seem to be getting! If you want to try Fatty 15 then feel free to use this discount code for 20% off!
Types of Fatty Acids and Their Benefits
Omega-3 Fatty Acids
Characteristics:Â Omega-3 fatty acids are polyunsaturated fats, which means they have multiple double bonds in their carbon chain. The most well-known omega-3 fatty acids include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).
Benefits:
Anti-Inflammatory:Â Omega-3s have potent anti-inflammatory properties, making them ideal for soothing irritated and inflamed skin.
Hydration: They help maintain the skin’s lipid barrier, which is essential for keeping the skin hydrated.
Skin Repair:Â Omega-3s aid in repairing damaged skin cells and improving overall skin texture and elasticity.
Common Sources:Â Fish oil, flaxseed oil, chia seeds, and walnuts.
Omega-6 Fatty Acids
Characteristics:Â Omega-6 fatty acids are also polyunsaturated fats. The most notable omega-6 fatty acid in skincare is linoleic acid.
Benefits:
Barrier Function: Omega-6s are crucial for maintaining the integrity of the skin’s barrier, which protects against environmental stressors and prevents water loss.
Skin Health:Â They help reduce inflammation and support overall skin health, making them beneficial for conditions like eczema and psoriasis.
Moisturization:Â Omega-6s keep the skin moisturized and supple.
Common Sources:Â Evening primrose oil, sunflower oil, safflower oil, and soybeans.
Omega-9 Fatty Acids
Characteristics:Â Omega-9 fatty acids are monounsaturated fats, with oleic acid being the most prominent.
Benefits:
Moisturization:Â Omega-9s deeply moisturize the skin, making it soft and smooth.
Anti-Inflammatory:Â They have anti-inflammatory properties that help calm irritated skin.
Skin Protection: Omega-9s help protect the skin from environmental damage and enhance the skin’s barrier function.
Common Sources:Â Olive oil, avocado oil, and almond oil.
Benefits of Fatty Acids in Skincare
1. Hydration and Moisture Retention
Fatty acids are essential for maintaining the skin's hydration levels. They help form the skin’s lipid barrier, preventing moisture loss and keeping the skin soft and supple. This is crucial for combating dryness and ensuring the skin remains plump and healthy.
2. Improving Skin Elasticity
Fatty acids like monounsaturated fats improve skin elasticity, making the skin appear firmer and more youthful. They also help reduce the appearance of fine lines and wrinkles by maintaining the skin’s structural integrity and promoting cell regeneration.
3. Anti-Inflammatory Properties
Many fatty acids have anti-inflammatory properties, which can help soothe irritated skin and reduce redness. This makes them beneficial for conditions like eczema, psoriasis, and acne. By reducing inflammation, fatty acids also help prevent further skin damage and promote healing.
4. Strengthening the Skin Barrier
A strong skin barrier is crucial for protecting against environmental stressors like pollution and UV radiation. Fatty acids help reinforce this barrier, keeping the skin resilient and healthy. This protection ensures that the skin can effectively defend itself against external aggressors and retain essential moisture.
5. Biohacking Benefits Beyond Skincare
Beyond their topical benefits, fatty acids play a significant role in overall health. They support brain function, reduce inflammation throughout the body, and contribute to cardiovascular health. Incorporating fatty acids into your diet and skincare routine can enhance both your internal and external well-being, making them a key component of a holistic biohacking strategy.
