If the Areola is Cut Open, Would It Heal Back to How It Was Before or with "Normal" Skin?

 All incisions heal with a scar. The skin adjacent to the scar is your skin. Scarring is unpredictable and a lot of your healing tendencies are genetically predetermined.

All incisions heal with scars. An accurate approximation with sutures or some alternative (steri-strips, glue) gives the best chance of a nice scar. If left open, the incision will heal, but has a greater chance of a wider scar. 

Thanks and best wishes.
