Baby had hands foot and mouth 2 weeks ago he has dry red circles were blisters were i'm applying aquafor will those scars go away or leave a mark ?

A little dark spot: will persist for a few weeks, no permanent scar is expected

Hope this helps. : Young children tend to be very resilient and good healers. Although I can't guarantee there will be no marks, but I can tell you that it tends to take a lot to scar a child...usually deep cuts. Things such as blisters tend to heal without a trace after a few months.
