Believe it or not, plastic surgeons have little control over your wound healing biology. It is important to close the wound with as little tension as possible, but other than that, your scar healing is largely determined by your genetics. Nevertheless, I am always impressed at how well most facelift incisions eventually heal. Although there is initially some redness to the incision while healing, in most people it is very will hidden.
In a typical facelift, the incision comes down in front of the ear, but behind the tragus so it is broken up nicely. Just like with any incision, a little redness can be evident for a few weeks but makeup can cover it up. Just be sure to see a facelift specialist because he/she will be the most experienced at obtaining scars that are well hidden and difficult to detect.
