In my practice, patients that need both a facelift and a laser resurfacing procedures typically have these done at the same time. This is generally safe when the settings are appropriate, and helps to reduce the overall downtime. If you have already had the facelift and are now seeking laser resurfacing, I would check with your surgeon for specific recommendations.
It really depends on what was done and what you plan on having done. It is common for me to perform skin resurfacing (with a laser or chemical peel) at the same time as a facelift. You really need to be seen in person as none of us can appropriately answer this with the limited information you provided.
