Transcript for Have scientists experimented with mixing COVID-19 vaccines?
Just one day. Dr. Ashton, she's here to answer your questions today. Let's start with number one. Scientists they experimented with mixing brands of covid-19 vaccines to see the results?

This is not the time to go cruising the aisles of the drugstore and try to wing this. See a board certified dermatologist who can treat it at the root cause, usually with something topical, as well as something systemic. Acutane, a major tool in that arsenal, but can be very effective in preventing those scars. You want to get to the point where you don't have them.
