Vegetable oils are intended primarily for the nutrition of dry skin, but that does not mean that combination skin or with oily tendency* should be excluded!
The skin is protected by an invisible bodyguard, the hydrolipidic film, made up of lipids coming from sebum. If this lipid film is damaged, a greater quantity of sebum will be produced and we will find an oily film on the skin. This is reactive seborrhea. Oils and therefore good quality fatty acids on oily skin, help limit this phenomenon and contribute to the balance of the skin.

I'll explain to you: our skin is protected on the surface by an invisible film, called hydrolipidic film. It protects us from external aggressions, for example prevents the water contained in our body from evaporating too quickly or even helps to make us waterproof(1)! Yes, without it, we would fill ourselves with water every time we take a bath!
Perhaps you have already guessed it from its name: this film is composed in part of fatty acids, that is to say lipids. These fatty acids come from sebum, a lipid mixture secreted by our sebaceous glands, in our hair and body hair! There are between 100 and 1000 sebaceous glands per square centimeter (cm2) of skin(2), imagine:
This small square has an area of 1 cm2, it contains between 100 and 1000 sebaceous glands! |
The production of sebum is more or less high depending on the person, their age, the level of stress and especially hormonal changes(3).And you will have understood, if this sebum production is too high, many lipids are found on the surface of the skin and this oily film loses its invisible character and is exposed to everyone's eyes! t9>
Now that you know the existence of this protective lipid film, I come to our question: why add oils to skin that already tends to be oily!
Imagine, your skin is like a small plant that must be taken care of: if the external conditions mean that the plant is well hydrated, well nourished then you will not water it. On the other hand, if the external conditions are not favorable, for example the weather is very dry, there is a lot of wind then you will water it.
It is the same for the skin: if the lipid intake is optimal, the signals are green, the skin is protected, it does not feel attacked and therefore, the sebaceous glands produce sebum normally. Conversely, if you clean your face too often or with products that are too aggressive, the lipids are damaged and the hydrolipidic film is unbalanced. |
The signals then turn red and to compensate, the sebaceous glands can locally produce much more sebum(4). This is then found on the surface and it is the return of the dreaded greasy film that you wanted to get rid of!
This astonishing phenomenon has a name, it is reactive seborrhea(1). According to the numerous publications that we have studied within our scientific team, it is due to localized regulation by our sebaceous glands in a completely autonomous manner. This has even earned them the name “brain of the skin” according to some researchers(5). Skin cells continue to surprise us!
Coconut, olive, flax, jojoba oil etc. All oils are different and not all are suitable for use on the face, especially if your skin tends to be oily on certain areas. I will explain to you in a future article the parameters to take into account, in particular the omega content or the extraction process. |
