What are the benefits of hazelnut oil on the skin?

Although it is suitable for all skin types, hazelnut oil is especially favored by combination to oily skin. Indeed, it is particularly rich in monounsaturated fatty acids such as the oleic acid (also known as omega 9), present in a mass fraction ranging from 71 to 87%. However, this lipid is part of the natural composition of sebum, a substance secreted by the body to counteract the dryness of the skin and hair. Oleic acid is therefore recognized by the constituents of the skin, and thus penetrates deeply to regulate sebum production by the sebaceous glands.

Furthermore, thanks to its dry texture, hazelnut vegetable oil has the advantage of leaving no oily residue.It is non-comedogenic (comedogenicity index = 0), meaning it does not clog pores and therefore does not promote the appearance of blackheads. It is an excellent ally for combination to oily skin types.

Due to its activity on oily skin, hazelnut oil is included in two treatments designed for these skin types:

• Thepurifying botanical blendwithpeony, whichpurifies and regenerates the skin during your sleep. This serum is applied at the end of your evening beauty routine, just before bed, on clean and dry skin.

• The blemish serum with 1% bakuchiol is designed to reduce pimples due to its antibacterial action. This treatment can be applied morning and evening, preferably at the end of the routine, before the day/night cream.

Hazelnut oil is also a good emollient and softening treatment fordry skin, thanks to its lipid content (mainly omega 9 and then omega 6). As a reminder, althoughsynthesized by the body, external supply (topically) of omega 9 is necessary to strengthen the skin's protective barrier. Indeed, these fatty acids constitute the hydrolipidic film, the layer that protects the skin from external aggressions and maintains its hydration level. Hazelnut oil is thus protective, restorative and softening. It gives the skin a silky touch without leaving a greasy film.

Thanks to the vitamin E and phytosterols it contains, this vegetable oil is a goodantioxidantcare to protect the skin from free radicals. As a reminder, these arereactive oxygen speciesproduced naturally by the body. However, when cells are faced withstress, they produce them in anexcessiveway. The sources of stress are numerous, the main ones being exposure to UVA, pollution, smoking, a diet too rich in fats and/or sugars. Free radicals are particularly unstable molecules due to theirsingle electron. They tend to react with other molecules to form apair of electrons, and then causedamage to cells, DNA, and proteins in the body. Aging is thus accelerated and wrinkles appear on the skin surface. Hazelnut oil is therefore a choice ally to fight against skin aging, mainly in mature skin.

Ourhazelnut vegetable oilis derived from the cold pressing of hazelnuts grown inFranceusing organic farming methods. It is recommended for mattifying and purifying shiny skin characterized by an overproduction of sebum and enlarged pores.

How to use it? Apply a few drops of oil on clean and dry skin, preferably in the evening due to its oily nature. Massage with upward circular movements, avoiding the eye contour.
