How to properly store your vegetable oils?

Skincare products based on plant oils are primarily composed of fatty acids (90% of the formula). However, these fatty acids are highly sensitive to oxidation, which can be triggered by various factors such as exposure to air, heat, interactions with the container, or light. Thus, the oxidative potential of a plant oil depends on the nature and concentrations of the fatty acids. For instance, the more double bonds a fatty acid has, the higher its rate of oxidation. If the fatty acids are altered, the plant oil can lose its benefits and even become toxic to the body. This can be identified by a change in the color or smell of the plant oil.

In order to slow down the oxidation process as much as possible and preserve their benefits, it is essential to store your vegetable oils under proper conditions. Above all, it is crucial to properly close the bottle after use to prevent air from entering. Next, opt for colored containers that protect from light. Even though some vegetable oils can be stored at room temperature, the "sensitive" vegetable oils should be kept in a cool place, preferably in the refrigerator. This rule is particularly applicable for skincare products based on hemp, grape seeds, black cumin, hazelnut, prickly pear, flax, rosehip, and so on...
