Can Mini Lift Also Get Rid of Acne Scars?

A mini-facelift will not improve your acne scarring unfortunately.  There are effective ways in treating this kind of scarring, such as laser resurfacing, dermabrasion, excising the area, and the Fraxel laser.  A mini-facelift  is a procedure that improves the look of an aging face.  It lifts the sagging skin, especially along the jawline, resulting in a more a youthfull appearance.  Consult your facial plastic surgeon to see what your best options would be.

A mini-facelift treats drooping of facial skin and underlying tissue. The muscle called the SMAS is often re-suspended and the excess skin removed. It is an excellent procedure for the patient who is showing early signs of aging with new jowl formation. Acne scars will look better for a few month since the skin is stretched, but as the skin stretches back the scars will return.
In order to treat acne scars, the skin needs to be treated directly. There are a number of options, some of which are lasers and dermabrasion. Seek out a skin/facial specialist for a more definitive answer. As for timing, as long the procedures are separated by around 6 months or more, it is more related to your priorities.
