You will be quite sore and swollen after your Mini Lift. I recommend that patients refrain from exercise and vigorous activity for at least two weeks after a lower facelift. Introduce your activities back into your routine gradually. Hiking, for instance, would be a better first step than Pilates, which might require some inversions that could be uncomfortable while your face is still swollen. Listen to your body, take it as slowly as you need to; you'll be back to your normal routine soon enough. I hope this helps.
I suggest my patients wait 2 weeks before resuming exercising. This recommendation will vary depending on your surgeons preferences, so definitely make sure you follow their recommendation. You have to wait till you are partially healed and that most of the bruising and swelling has subsided.
