Although ingredient-based skincare is popular nowadays, natural plants are still an integral part of skincare products, and many of them also have very strong effects. For example, rose is anti-aging, Centella and calendula soothe the skin, and sea fennel promotes cell repair. 

How researchers determine whether a natural plant is effective When it comes to the effectiveness of natural plants, many people may think of ancient remedies, or some wonderful story, "somewhere on the African continent, the good XX tribe believed that XX herb could cure diseases and bring good luck to everyone". Indeed, these experiences, passed down from generation to generation, can be an inspiration for researchers. But to confirm the efficacy of a natural plant, rigorous scientific research is needed. In ancient China, for example, it was always believed that white peony could make the skin white. So the basic research department of the L'Oréal Group, the world's largest cosmetics company, would first test whether white peony extract could inhibit melanin synthesis in melanocytes in vitro. After proving its efficacy in cells, it is then further confirmed on 3D skin models and in humans.

Then there is sea fennel, which grows on the Brittany coast and has particularly strong regenerative powers and rich nutrients, which ancient French sailors took with them when they went to sea. L'Oréal Group, in collaboration with its raw material suppliers, found that it promotes the division and proliferation of keratinized cells, increases the thickness of the stratum corneum and repairs the damaged skin barrier of sensitive skin.

We can only say that a natural plant works if the efficacy is proven through scientific research methods.
