How long do I need to wait after facelift to get skin treatments like peels, microdermabrasion etc.?

Usually between 2 and 4 weeks before any superficial treatments. The more minor procedures can be done at the same time as the lift in many cases.  Best wishes, Dr. T. 

Although the procedures you mentioned can be safely performed 4 weeks after a facelift there are other procedures (lasers, micro-needling, etc) that are best delayed until there has been more solid healing.  A lot also depends on the type of facelift that was performed.  Always check with your surgeon before making a decision to undergo any of these treatments within the first 6-12 weeks after surgery.
