The main components of essential oils and the common plant oils we see in our daily lives are higher fatty acid glycerides. The main components of essential oils are volatile small molecules such as terpenes, nitrogen-containing compounds, and phenolic compounds produced by secondary metabolism in plants. Because essential oils are a mixture of fat soluble aromatic molecules, and aromatic molecules themselves have a small molecular weight, they can easily pass through the skin barrier, quickly reach the dermis layer, and enter capillaries and lymphatic vessels. However, even the best essential oils cannot be "directly" applied to the skin, as this can burn the skin and have the opposite effect.

 
1: Difficult to dissolve in water, limiting its dosage in cosmetics
 
2: Easy to evaporate at room temperature, causing changes in the fragrance and style of cosmetics
 
3: Poor stability, sensitivity to light, oxygen, and heat, easy to decompose and deteriorate, affecting the beauty efficacy of cosmetics

1. Good water solubility

2. High stability

3. Strong skin permeability

4. Long term sustained release
