What is Linoleic Acid ?

Linoleic acid is a polyunsaturated fatty acid of the omega-6 family, essential for skin and body health. This fatty acid is termed “essential” because the human body cannot synthesize it, which means it must be supplied through the diet or external care. Linoleic acid is found in many vegetable oils, such as sunflower, safflower and grapeseed oil. It is particularly prized in cosmetics for its moisturizing, repairing and anti-inflammatory properties. Its ability to strengthen the cutaneous barrier makes it an ideal ingredient for skin and hair care.

Present in our regenerating oil, linoleic acid is an essential fatty acid from the omega-6 family. It helps to ensure a good level of hydration and improve the skin’s natural protection. In fact, it helps retain water in the epidermal cells, which is essential for maintaining healthy, well-moisturised skin.

Where does Linoleic Acid come from ?

Linoleic acid is mainly obtained from plant sources, notably omega-6-rich oils such as sunflower oil, soybean oil, safflower oil and grapeseed oil. In food, it is found in seeds, nuts and certain meats. In cosmetics, it is often extracted from vegetable oils or incorporated as a pure oil. The wide availability of this fatty acid in nature makes it a precious and accessible resource. Linoleic acid plays a crucial role in skin barrier integrity, cellular health and moisture regulation.

Properties and active ingredients :

Linoleic acid is an active ingredient highly prized for its many beneficial properties for skin and hair. Here are its main characteristics and actions

Restores the skin barrier : By reinforcing the skin’s lipid barrier, linoleic acid helps maintain hydration and protect against external aggressions.
Anti-inflammatory properties : This fatty acid has natural anti-inflammatory effects, soothing skin irritations and reducing redness and inflammation.
Improves skin texture : Linoleic acid helps reduce skin imperfections and irregularities, promoting a more even, luminous complexion.
Hydration and sebum regulation : It maintains optimal hydration levels without weighing the skin down, and also helps balance sebum production, beneficial for oily or acne-prone skin.
Antioxidant effect : Thanks to its ability to protect cells against oxidative stress, linoleic acid helps slow the signs of aging and preserve skin health.

What are the benefits of linoleic acid ?

It offers numerous benefits for skin, hair and general health. Here are the main benefits of this essential fatty acid :

Hydration and moisture retention in the skin : By strengthening the lipid barrier, linoleic acid helps retain moisture in the skin, leaving it hydrated, supple and soft.
Reduced skin imperfections : Acne-prone skin benefits from linoleic acid’s anti-inflammatory and sebum-regulating properties, helping to reduce blemishes and redness.
Prevent skin aging : Linoleic acid protects skin from environmental damage and free radicals, helping to slow the signs of aging and prevent the appearance of wrinkles.
Improves hair suppleness and shine : On hair, linoleic acid helps restore moisture, improve shine and reduce frizz, while strengthening the hair fiber.
Skin barrier reinforcement and protection : By strengthening the skin barrier, it helps prevent irritation and feelings of tightness, which is beneficial for dry, sensitive skin.

BENEFITS :

• Preserves skin hydration while strengthening the skin barrier
• Is rapidly and effectively absorbed by the deep layers of the skin
• Soothes and calms sensitive skin

How should Linoleic Acid be consumed ?

Linoleic acid can be incorporated into your daily routine through diet, or applied topically to the skin and hair. Here are the main ways to enjoy its benefits:

Diet: Is found in foods such as seeds (sunflower, flax), nuts (walnuts, hazelnuts), and certain vegetable oils (sunflower, grapeseed, safflower). By incorporating these foods into a balanced diet, we can meet our essential fatty acid requirements.
Moisturizing serums and creams: In cosmetics, this acid is often included in serums, creams and lotions for its moisturizing and protective properties. It is particularly useful for dry, sensitive or acne-prone skin.
Hair care: oils rich in linoleic acid are often found in hair masks, conditioners and serums to moisturize, strengthen and soften hair. Applied to the ends, it helps prevent split ends and reduce frizz.
Facial oils: Linoleic acid is often found in vegetable oils for the face, such as rosehip or grapeseed oil, which can be applied alone or added to a skincare routine for a nourishing, balancing effect.

Note: People with oily or acne-prone skin can particularly benefit from linoleic acid, as it can help regulate sebum and reduce blemishes. For external use, a skin test is recommended before applying to large areas of the face.

Any side effects ?

Linoleic acid is generally well tolerated, but certain side effects may occur, particularly if unsuitable products are used or in cases of sensitivity:

Rare skin irritations: Although rare, some people may experience slight irritation or redness after applying products containing linoleic acid. A skin test is recommended before first use.
Comedogenic effect (rare): Although linoleic acid is generally beneficial for oily and acne-prone skin, some oils rich in omega-6 fatty acids can be comedogenic on certain skin types. So it’s important to choose lightweight products, especially if you have clogged pores.
Risk of oxidation: Oils rich can oxidize rapidly if exposed to heat or light. We recommend storing products containing this fatty acid in a cool, dark place.
Dietary interactions: Too much omega-6 in the diet can lead to an imbalance with omega-3. It is therefore recommended to maintain a balance between the two types of fatty acids for optimum health.
