In order to have a good quality oil no matter what you want to use it for, there are certain factors to look at when buying it and the method of oil extraction is one of them. There are several ways to extract oil from plants: cold or hot pressure extraction, maceration, solvent extraction...Among all the possibilities, only cold pressure extraction and maceration extraction offer superior quality oils with intact skin properties.
Cold pressure extraction: In a mechanical press, the oleaginous fruits are crushed until a pure and 100% natural oil is obtained.
Extraction by maceration: This method is only used for oils obtained from a plant. The flower, root or fruit are being macerated in a neutral oil (olive or sunflower) for several weeks. The oil obtained at the end of this period is filtered and only the oily macerate is kept and then used.
Skin types, which oils to use for the face?
Les huiles pour peaux irritées
Lorsque votre peau est irritée, toutes les huiles ne conviennent pas. En effet, il est préférable d’utiliser une huile avec des propriétés apaisantes pour calmer l’irritation. Les huiles à employer dans ces cas-là doivent être riches en un type d’acide gras très spécifique : les oméga-3. Ces acides gras polyinsaturés sont appelés « essentiels » car notre organisme ne peut pas s’en passer. Ils sont utiles pour restaurer le film hydrolipidique de la peau et ainsi apaiser les inflammations de l’épiderme.
Les huiles pour peaux sèches
Les peaux sèches le sont généralement car comme pour les peaux irritées, elles n’ont (presque) plus de film hydrolipidique protecteur. De plus, les peaux sèches sont aussi fragilisées en profondeur. Ainsi, en plus d’oméga-3, elles auront besoin d’être nourries et hydratées grâce à des agents supplémentaires.
Les huiles pour peaux grasses
L'utilisation d’huiles sur les peaux grasses The use of oils on oily skin may seem unsuitable, but some of them help the epidermis to regulate its sebum level thanks to specific fatty acids. These oils rebalance the skin's hydrolipidic film and help control skin shine.
Les huiles pour peaux mixtes
Combination skins are those whose T-zone - forehead, nose and chin - tends to release too much sebum, while cheeks and cheekbones are normal or even slightly dry. The oils to be used in these cases must then know how to regulate the sebum rate in both directions (too oily or too dry) and also be composed of alpha-hydroxy to revitalize the face properly.
Les huiles pour peaux boutonneuses
Acneic skin is very sensitive and is often part of the daily life of teenagers, but not only. The problem comes from hyperactivity of the sebaceous glands of the face. The reflex is often to dry the face and the glands but this is not the optimal solution.
The sebum excess informs the skin of the presence of too many bacteria. It is therefore necessary to eliminate them with the help of a suitable oil. In addition, blackheads form as a result of the oxidation of excess sebum on the skin that clogs the pores. It is therefore better to use dry oils that are not very sensitive to oxidation such as jojoba, date or tea tree.
Les huiles pour peaux matures
Mature skin above all needs oils with regenerating properties. The carotenoids they contain prevent skin aging. Oils must also be rich in antioxidants and essential fatty acids to prevent skin aging and therefore wrinkles.
