Wow, I use the ez Injector and I’ve never had marks like that. That almost looks like some kind of reaction. Maybe someone has had this happen and knows more about it than I do.
@AdinaFloyd I thought the same thing, but I have used This PDRN before. Even already used the other syringe in the same box. We have lost power multiple times this year for 3 hurricanes. Maybe I’ll throw away and use my fresh stuff that arrived yesterday. Thanks for input.
