Swelling 10 days after Silhouette InstaLift. Is this normal?

You probably had some swelling after the procedure, which is normal after any facelift procedure. Wait for 5-7 days and the swelling should subside. If not, consult the surgeon who did your procedure or a board certified plastic surgeon near you. 

Yes, some degree of swelling is very common following the InstaLift procedure. This is a normal part of the healing process, and generally resolves by around the 2-week mark. If you still feel that the swelling looks too significant after that point or you also notice heat or increased tenderness in the treatment area, schedule a follow-up appointment with your provider.

Though not typical for swelling to last that long it is not uncommon. You can use some warm compresses to the area but do not rub the area. Be gentle in the area when washing. Be patient and the swelling should resolve. Good Luck!
