This cutting-edge serum packs science-backed ingredients with Renewosome exosome technology. This is plated most intense version of the serum. Combat visible signs of aging and damage with the concentrated power of 1+ trillion platelet-derived exosomes in every bottle. I purchased a two-pack over the summer, but I have very sensitive skin, so I'm selling the other one. The product is fragrance-free and should not irritate most skin types unless you are hypersensitive like me:) It is unopened and sealed. Retails for $258.00, and this skincare brand does not go on sale often, if at all. I'll be selling for $175.00, which is an over 27% savings!
