Answer:
Secondary facelifts are usually technically easier to perform than primary ones. Dissection of facelift scar planes usually results in much less bleeding which significantly reduces operating time. Little excess skin can be excised. In fact, good cosmetic results are usually because of a redistribution of skin rather than any excision of excess skin. As a result, it is often necessary to extend the dissection further beyond the original limit of undermining, sometimes joining up with the undermining from the opposite side. The recovery period is usually shorter and the incidence of skin sloughing is less since the primary procedure acts as a delay.
