Many cosmetics contain essential fatty acids (omega 3, omega 6). What is their role in the skin, the hair? Response elements.
Omega are lipids, fats. There are two categories: essential fatty acids (Omega 3 and Omega 6) and non-essential fatty acids (Omega 9). These fatty acids are divided into three main groups: saturated fatty acids, monounsaturated (omega-9) and polyunsaturated (Omega 3 and 6). What differentiates them is the presence or absence of a double bond (in the carbon chain, a chemical characteristic). Long chain polyunsaturated fatty acids are very interesting because "once ingested, they are processed by the body and assimilated," says Patrice Bellon, Doctor of Pharmacy and President of the French Society of Cosmetology.
Omega 3 and 6 are called "essential" because they are not manufactured by the body even though they are indispensable. "Omega 3 and 6 are essential. They feed the cells, provide good cell development. In case of deficiencies, some disorders may appear as inflammatory diseases, heart disease. They are essential to the organization, operation and to health. When one stops using the mechanisms slow down, "recalls our expert.
To stay healthy, it is important to eat foods rich in essential fatty acids (oily fish, nuts) and for a young and beautiful skin, it should be to head for cosmetics based on fatty acids.
Omega like my skin
Fatty acids are very interesting in our care, even if the expert in cosmetic emphasizes that there is no assets on which many professionals communicate "Omega in cosmetics are not really a marketing argument, that is not such as coenzyme Q10. " Yet, even if the fatty acids are not a marketing argument ingredients which they are extracted they are a little more.
Fatty acids are used in particular to strengthen the skin barrier, maintain a good level of skin hydration, fight against inflammation, promote healing, to fight against free radicals. "They offer good protection and help maintain a good level of moisture barrier," informs Dr Bellon.
Omega 3
Composed primarily of linolenic acid, these polyunsaturated fatty acids (PUFAs) play a key role barrier function. The omega-3 linolenic acid has an anti-erythema effect and is prized for its soothing and softening properties. "Omega-3s have anti-inflammatory, so it makes sense that they are used to soften the skin. Furthermore, it is a very good emollient (softens and soothes the skin)."
In our plate, they are mainly in the "fatty fish, certain algae, walnut oil, or even fish oil capsules," Patrice Bellon list.
Omega 6
Composed mainly of linoleic acid, they also act as a barrier for the skin but are also useful in anti-aging for their action on the skin elasticity. "Omega 6 are found in vegetable oils such as safflower oil, corn, oilseeds, seeds."
Omega 9
Mainly consisting of oleic acid, even if they are not essential (the body may be synthesized) the omega 9 are among the important fatty acids. They are in particular in the sebum and are useful for their action on the hydration, skin protection, flexibility and elasticity of the skin.
