disappointed [SEP] i just received my package and noticed the package was ripped and that s okay because after opening everything was sealed but when i opened the serum it was tinted orangewhich means it oxides and no longer is good it was completely sealed and the expiration date was far from now i haven t used the derma roller yet so i can t speak on how useful it is i ll update later but i m really dissatisfied that i can t use the serum
