Can exercise or sexual intercourse after a facelift cause a bad result?

I'd suggest following your surgeons guidelines. I normally let my patients exercise after a week. The biggest risk is getting your blood pressure up and having a hematoma. That risk is pretty low but depends on what type of facelift and any risk factors for bleeding.

Yes, resuming exercise or sexual intercourse too soon after a facelift can potentially cause complications, such as increased swelling, bleeding, or poor healing, which may negatively impact the results. Generally, it's advised to avoid strenuous activities for at least 3 to 4 weeks post-surgery, but your surgeon will provide personalized recommendations based on your specific situation. Following their guidelines is crucial for optimal healing and achieving the best possible outcome.
