Healing after blepharoplasty of the upper eyelids when performed with the usual skin incision can take from one week or longer. Regarding lower eyelid surgery, the incision scar may be on the skin or in the inner eyelid. There are multiple options for incision sites depending upon a personal evaluation. That being said...
Of course, other factors such as smoking can impair healing. You should consult with a Board Certified surgeon who would have to evaluate you and give you specific recommendations and advice and have the expertise and experience to serve you best.
