if you sleep alone [SEP] the marketing blurb says among other things this advanced man face care formula features stem cells to help revive the skin and smooth out imperfections well stem cells if they were actually somehow harvested in a cosmetics container mixed with various other chemicals and ingredients would necessarily be dead and therefore completely irrelevant and of course the stem cells would help address things such as diabetes and repair of heart muscle following heart attack not zits on ones face not to mention that they would need to be live and human cells so i am quite confident that the stem cells claim is untrue and even if it were true the presence of dead stem cells in a cream would make zero differenceother than that the cream is thick and as other reviewer found it has an aggressive smell that reminded me of noxzema so i would never use it during the day at night it would probably be okay if used by men who sleep alone
