The answer depends on which and how many non-surgical procedures you are having, who is providing it and where you live. Knowing the causes of aging will help answer your question. One approach does not substitute for another and often they can be done at the same time. The most important thing is to find the most skilled Plastic Surgeon available and he/she will determine what is needed and the timing especially since you did not provide photos. Fillers and resurfacing procedures at the same time or following a Face Lift procedure makes Sense for most. There is a higher risk in smokers however.This is because you age by three factors - sagging (through gravity and time), loss of volume (counteracted by fillers), and skin texture (determined by environmental and genetic factors). Your fillers should enhance your effect of the lifting if placed appropriately by addressing one of the causes of aging. Most often one of these factors is more out of balance than another and therefore your procedures should customize for what is most needed. Often fillers alone can "stall" the inevitable as they only correct one aspect of aging.Facelift and Skin resurfacing procedures (laser, Ulthera or Thermage ) and fillers are synergistic so as long as you wait until the Sculptra injection site is soft you should do fine. Not a problem and there is no problem with the timing for a facelift. Sculptra, Radiesse, Jeuvederm, Restylane, your own fat and other fillers address volume issues, resurfacing procedures corrects surface flaws associated with aging and face lifting addresses the sagging loose skin. Resurfacing procedures address skin texture, color variation (e.g. sun spots)- so all three are synergistic and complementary. It is very common in my practice to do all three approaches to rejuvenation at the same time
