Are the ingredients of fermented lipstick safe?

The ingredients of fermented lipstick are considered to be generally safe. The main components of fermented lipstick include natural plant components such as lactic acid bacteria fermentation, trehalose, DNA extract, etc. These components are very common in the cosmetics industry and often appear in natural cosmetics in recent years. Although the yeast extract sounds worrying, it is actually an effective ingredient, which can promote the cell metabolism and repair of lip skin and improve the antioxidant capacity of lip.

Consumers are advised to choose suitable cosmetics according to their skin types and needs, and pay attention to the production batch, instructions and shelf life of the products.
