Whatever they are, I'm pretty sure you can't remove them yourself. If you keep after them, they're sure to remain and look red.
The dermatologist most likely thought they were beign growths of some sort (perhaps
molesBirthmarks - pigmented
Gestational trophoblastic disease
Hydatidiform mole
Pth.) Otherwise, she wouldn't have suggested removing them by a superficial means like freezing.
As to what she thinks they are, since you took the trouble to pay her a visit, whey not call and ask her?
Best.

Thanks for nothing.
