Plant stem cells in facial product?

Instead of human stem cells, most marketed stem cell facial creams contain plant stem cell extract (these do not require FDA approval). Often, they are marketed as stem cells from "resilient" plants with “renewal” properties that can survive harsh environments. ⠀
⠀
To perform their amazing functions, these stem cells need to be alive and in specific conditions. Upon processing to form the cream, they are already dead. The only functional properties of the creams are limited to what was ‘extracted’ to the bottle. ⠀
⠀
Studies have shown that active ingredients, such as antioxidants, of specific plant extracts do benefit the skin. Different studies used different extracts and examined on different functions. So, either the different plants have different benefits, or that other functions are not tested (you can read more about them in the reviews referenced). Of course, more research has to be done - e.g. what is the exact profile of these extracts? ⠀
⠀
So, there might be some benefits from the stem cell extract, but definitely not to the extent that they are promised!
