The raw materials of olive ingredients are widely used in cosmetics, including olive oil and water-soluble olive oil (added to water-containing cosmetics to avoid the hydrolysis of olive oil and the unpleasant smell, adding PEG to olive oil.) , plant squalane derived from olives (original from Xianting, France), olive leaf extract (original from B&C in Italy, trade name is BT, later acquired), etc.
Olive leaf extract is the most expensive. According to information, olive polyphenols are responsible! We started adding BT to a toner 15 years ago, and it has really good soothing and repairing effects!
As for how to determine whether it has been added, it is difficult to draw a conclusion by measuring the components. Olive leaf extract is a comprehensive extract, and the content of its components is not specified! Raw material manufacturers can even collect some olive leaves, boil them, record them as olive leaf extract, and sell them to cosmetic brands with conceptual additives.
Therefore, cosmetics brands need time to mature. They are not designed to sound good and look good and then conceptually add an ingredient and promote it as a miracle elixir. This is the type of brand that has quickly become popular and then disappeared into thin air in recent years.
