The role of polyunsaturated fatty acids (PFAs)

Polyunsaturated fatty acids (PFAs) are key components of the diet, essential for the proper functioning of the human body. VFAs are the basic material for the biosynthesis of eicosanoids, including prostaglandins, prostacyclins, thromboxanes and leukotrienes, which play an important role in regulating inflammatory processes and other physiological functions. They also take part in cholesterol transport and metabolism and are integral components of cell membrane lipids.

You can also find them in dietary supplements, which can significantly affect the health and appearance of your skin by working from the inside out. The key nutrients provided by the supplements support skin function, strengthening its structure and improving its overall condition. With properly selected supplements, we can provide the skin with substances that are lacking in the daily diet.

Division of polyunsaturated fatty acids

VFAs are divided into two main families: omega-3 and omega-6. The key fatty acids in each of these families are:

Omega-3:

• α-linolenic acid (ALA)
• Eicosapentaenoic acid (EPA)
• Docosahexaenoic acid (DHA)

Omega-6:

• Linoleic acid (LA)
• γ-linolenic acid (GLA)
• Arachidonic acid (AA)

Each of these fatty acid groups has unique biological properties that are related to the position of the double bonds in their molecular structure.

Which fatty acids are more important for health?

Both families of fatty acids, omega-3 and omega-6, are essential for health, but have different functions in the body:

Omega-3:

Omega-3 fatty acids, especially EPA and DHA, have strong anti-inflammatory properties. They are crucial for brain and eye health and support the development of the central nervous system both during the fetal period and after birth. Omega-3s also play an important role in the prevention of cardiovascular disease by reducing cholesterol levels, inhibiting platelet aggregation and lowering blood pressure.

Omega-6:

Omega-6 acids, such as linoleic acid and γ-linolenic acid, are important for maintaining healthy skin and regulating inflammatory processes. Linoleic acid is a precursor to the synthesis of other fatty acids of the omega-6 family, which help treat ulcers, diabetes and obesity. Arachidonic acid, another important omega-6 acid, is essential for the development of a child’s brain during the fetal period and in the prevention of mental retardation.

Importance of CCIs for the skin

The skin is a protective barrier that maintains a balance between the body’s internal and external environments. The health of the skin largely depends on the presence of adequate lipids, including ceramides, free fatty acids and phospholipids, which form the intercellular “cement” that is key to maintaining the hydration and integrity of the skin barrier.

The role of omega-6 fatty acids for the skin:

Linoleic acid (omega-6) is an essential component of ceramides in the stratum corneum. Linoleic acid deficiency can lead to skin barrier dysfunction, manifesting as dry skin, reduced elasticity and increased susceptibility to irritation. γ-linolenic acid (GLA), which is formed from linoleic acid, also plays a key role in maintaining skin health, especially for inflammation and atopic dermatitis.

The role of omega-3 fatty acids for the skin:

Omega-3 fatty acids, especially EPA and DHA, have strong anti-inflammatory effects, which is important in the context of protecting the skin from UV damage. They reduce the secretion of pro-inflammatory substances, reduce the effects of sunburn and promote the skin’s repair processes. α-linolenic acid (ALA), another key omega-3 acid, is incorporated into cell membrane phospholipids and ceramides, which helps maintain skin hydration and epidermal barrier integrity.

Polyunsaturated fatty acids, especially omega-3 and omega-6, play a key role in maintaining the health of the skin and the entire body. They are essential for the synthesis of eicosanoids, which regulate many physiological processes, including inflammation. A deficiency in VFAs can lead to numerous health problems, including skin dysfunction. Therefore, it is important that the diet is rich in these fatty acids, which can be achieved by increasing the intake of fish, vegetable oils and fruits and vegetables.

The synergistic effect of supplements and care leads to better results than using them separately. Supplementation supports the skin from within, supplementing dietary deficiencies and supporting natural regenerative processes. External care, on the other hand, acts immediately, providing the skin with essential ingredients and creating a protective barrier.

Discover our bestselling Lipid Repair Balm

It’s a formula with a creamy and silky texture that melts into the skin for long-lasting softness. Rich in oils containing essential free fatty acids (FFA), ceramides and cholesterol. Thanks to the content of lipids, identical to those naturally found in the skin, it effectively replenishes their content in the skin, improving its hydration. Accelerates the healing and regeneration processes of the skin, as well as protects it from free radicals. Softens, smoothens and improves skin elasticity bringing immediate relief and comfort. The lotion is recommended for the care of very dry skin, with symptoms of loss of elasticity and tension.

Very high antiradical activity (99.37%) was demonstrated.
