About exosomes
What exosomes are
Exosomes are tiny vesicles cells use to carry signals to one another. In a cosmetic serum they are an ingredient, not a treatment. Cellara Serum uses exosomes sourced from single birth placental donors, processed cell free in Florida and screened every lot.
Where ours come from
Amniotic fluid and umbilical cord Wharton's jelly, from single birth donors, processed cell free in Florida. Each lot is screened before it ships.
How we talk about them
We describe appearance and feel only, never what the skin does. We say a serum can be part of a routine that leaves skin looking smoother and more hydrated. We don't say it regenerates, repairs, stimulates collagen, treats, or cures anything. The full list of approved wording is in the approved language sheet.
