This is a kora organic plant stem cell retinol alternative serum. By far one of there most popular serium and people can’t get enough of it. It works just like it says it does if not better. Once you start using it you will never stop. It’s pricy for a reason and that’s because it work better that any other serum I’ve came across. Message me for questions have smaller bottles if u want to test it but can almost guarantee it will be a game changer to your skin!!
