What is linoleic acid?
Linoleic acid is a polyunsaturated fatty acid from the omega-6 family, essential for skin and body health. This fatty acid is called "essential" because the human body cannot synthesize it, which means that it must be provided through food or external care. Linoleic acid is present 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 skin barrier makes it a preferred 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 ensure a good level of hydration and improve the natural protection of the skin. In fact, it helps retain water in the cells of the epidermis, which is essential for maintaining healthy and well-hydrated skin.
Where does linoleic acid come from?
Linoleic acid is primarily obtained from plant sources, including oils rich in omega-6, 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 integrated in the form of pure oil. The wide availability of this fatty acid in nature makes it a valuable and accessible resource. Linoleic acid plays a crucial role in skin barrier integrity, cellular health, and hydration regulation.

How to consume linoleic acid?
Linoleic acid can be integrated into the daily routine through food or as a topical application for the skin and hair. Here are the main ways to benefit from its benefits:
- Food : Linoleic acid is present in foods such as seeds (sunflower, flax), nuts (walnuts, hazelnuts), and certain vegetable oils (sunflower, grapeseed, safflower). By integrating these foods into a balanced diet, you can meet your essential fatty acid needs.
- Serums and moisturizers : In cosmetics, linoleic 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 hydrate, strengthen and soften hair. Applied to the ends, it helps prevent split ends and reduce frizz.
- Facial oils : Linoleic acid is often present in vegetable facial oils, such as rosehip or grapeseed oil, which can be applied alone or added to a skincare routine for a nourishing and balancing effect.
Note : People with oily or acne-prone skin may particularly benefit from linoleic acid, as it can help regulate oil and reduce blemishes. For external use, it is recommended to perform a skin test before applying it to large areas of the face.
Any side effects?
Linoleic acid is generally well tolerated, but certain adverse effects may occur, particularly if unsuitable products are used or in the event of sensitivity:
- Rare skin irritations : Although rare, some people may experience mild 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 may 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 in linoleic acid can oxidize quickly if exposed to heat or light. It is recommended to store products containing this fatty acid in a cool place and away from light.
- Food interactions : In case of too high intake of omega-6 in the diet, an imbalance with omega-3 can occur. It is therefore recommended to maintain a balance between the two types of fatty acids for optimal health.
