Plant-derived exosomes

Exosomes are vesicles — small membrane-bound parcels that cells release and other cells take up. In cosmetics the word covers material derived from a plant rather than from human or animal cells. Perla’s are drawn from truffle, and appear on the ingredient list as Tuber melanosporum and Tuber magnatum extract.

This is a young ingredient class and it is worth being plain about that. What the pack can support is the extract and its origin. Anything past that is not something an ingredient list is able to say.
