It's been 8 months since my face-lift. Will this white scar go away?

Some patients tend to lose functional melanocytes (pigment producing cells) in and around scars.  That is unfortunate because it can make an otherwise acceptable scar, unacceptable in appearance. The best options in my opinion are to either excise the scar while minimizing trauma to the skin - e.g. gentle handling of tissue, minimal use of cautery - or to use a fractionated laser to blend the scar by encouraging the migration of melanocytes into the area of hypopigmentation (white skin). I might start with the latter because there is no guarantee that the problem won't recur after surgery to revise the scar. Best wishes. 

Thank you for your question and for attaching photos. This is actually a very acceptable scar. It is thin and light. The problem is it does not blend well with the surrounding tissue. At 8 months out you probably are not going to see an improvement. You may consider a scar revision, but unfortunately the scar may look the same or could end up worse. I am sorry you are not happy with the scar, but my honest answer is not much can be done to improve it.

Your scar is likely in its final state based upon color and time since surgery.  Your surgeon should be familiar with this issue and should have options for you.  Go to him/her prior to attempting any self-treatment or miracle cures offered by other practitioners.  Best of luck.
