Vitamin F in Hautpflege: Alles, was du wissen musst

Overview of Vitamin F

• Sourcing: Mainly derived from plant oils such as flaxseed oil, soybean oil, sunflower oil, and hemp oil. These oils are rich in linoleic acid and α-linolenic acid.
• Effects on the Skin: Strengthens the skin barrier, reduces inflammation, provides moisture, and supports cell regeneration.
• Ideal for: Individuals with dry, sensitive, inflamed, or aging skin, as well as those with skin issues like acne or eczema, benefit greatly from Vitamin F.
• Interesting Fact: Linoleic acid is the most abundant fatty acid in the epidermis and is essential for the formation of ceramides, which are crucial for a healthy skin barrier.
• Other Names: Also known as linoleic acid (LA) and α-linolenic acid (ALA), sometimes referred to as omega-6 and omega-3 fatty acids.

The Effects of Vitamin F

Vitamin F, comprising linoleic acid (LA) and α-linolenic acid (ALA), offers several positive effects on skin health.

1. Strengthening the Skin Barrier: Enhances the skin barrier by integrating into the phospholipid and triglyceride fractions of the skin. These fatty acids are essential for the formation of ceramides, which strengthen the skin barrier and protect the skin from moisture loss. A study showed that supplementation with ALA and LA improved the skin barrier in a reconstructed skin model by reducing testosterone absorption and increasing levels of eicosapentaenoic acid and docosapentaenoic acid.
2. Anti-inflammatory Properties: Proven to have anti-inflammatory properties. Linoleic acid and α-linolenic acid reduce the production of pro-inflammatory mediators like prostaglandins and leukotrienes. These properties make Vitamin F particularly useful in treating inflammatory skin conditions like acne and eczema. A study demonstrated that linoleic acid improved the symptoms of atopic dermatitis by modulating the skin barrier and reducing inflammation.
3. Moisturizing: The moisturizing properties of Vitamin F are crucial for maintaining hydrated and supple skin. Linoleic acid is a skin-identical substance that helps reduce transepidermal water loss (TEWL) and increase skin hydration. This is particularly important for individuals with dry skin or skin barrier disorders.
4. Treatment of Skin Conditions: Proven effective in treating skin conditions like atopic dermatitis and acne. It can alleviate symptoms by repairing the skin barrier and reducing inflammation. A study showed that the topical application of linoleic acid reduced the size of microcomedones by 25%, indicating an improvement in acne symptoms.

Proper Use of Vitamin F

• Frequency of Use: Can be used daily, ideally twice a day, to achieve optimal results. Regular use is important to fully benefit from the product.
• Concentration: Products with a concentration of 2-5% linoleic acid are often sufficient to achieve noticeable improvements. Higher concentrations can be beneficial for more severe skin issues.
• Combination: Can be effectively combined with other moisturizing and anti-inflammatory ingredients such as hyaluronic acid, ceramides, and niacinamide. These combinations can have synergistic effects and further enhance skin health.

What is Vitamin F?

Vitamin F is not a single substance but a term for several unsaturated fatty acids, mainly linoleic acid (LA) and α-linolenic acid (ALA). Linoleic acid is an omega-6 fatty acid, while α-linolenic acid is an omega-3 fatty acid. Both have multiple double bonds in their chemical structure, making them essential components of cell membranes. These fatty acids are essential because the body cannot synthesize them and they must be obtained through diet.

Occurrence of Vitamin F in the Skin

Vitamin F, especially linoleic acid, is a natural component of human skin. Linoleic acid is the most abundant fatty acid in the epidermis and plays a crucial role in maintaining the skin barrier and hydration. Adequate linoleic acid supply is essential for the formation of ceramides, which are vital for the skin barrier and protection against transepidermal water loss.

Linoleic Acid vs. Oleic Acid: What is the Difference?

Linoleic acid (LA) and oleic acid (OA) are both unsaturated fatty acids but differ in their structure and function.

• Linoleic Acid (LA): An omega-6 fatty acid with two double bonds. It is essential for skin barrier function and has anti-inflammatory properties. Linoleic acid is a key component of the epidermis and contributes to the formation of ceramides, which strengthen the skin barrier. A deficiency in linoleic acid can lead to a weakened skin barrier and increased susceptibility to skin problems.
• Oleic Acid (OA): An omega-9 fatty acid with a single double bond. It can penetrate the skin and act as a penetration enhancer. However, oleic acid has the potential to cause skin irritation, especially in sensitive skin. A study showed that oleic acid in low concentrations does not cause significant morphological changes in the skin, but higher concentrations can lead to mild skin irritation.
