Do I need a facelift, neck lift and brow lift?

If your brow is not droopy then you don't need a browlift at the same time. Ideally you should see a few different facial specialists for consultation and then you can get a good idea of what is best for you.

Based on the details you’ve shared, it sounds like your surgeon is being thorough in addressing the potential impact of a facelift on other areas of your face, specifically the lower eyelids and brow.
For the lower eyelid skin pinch your surgeon likely wants to ensure that the facelift doesn't inadvertently create excess skin in the lower eyelid area, which sometimes happens when lifting adjacent facial areas. A lower eyelid skin pinch can address any mild redundancy, which should be a straightforward addition if needed.
For the brow lift- the need for a brow lift may seem surprising, especially if your brows don’t currently sag. However, your surgeon’s point about "bunching" refers to how a facelift can sometimes create tension that inadvertently shifts tissue upwards, affecting the brow position. A brow lift, in this context, wouldn’t aim to raise your brows dramatically but rather to maintain a harmonious, natural look with the lifted mid and lower face.
Ultimately, the brow lift isn’t always a necessity but is sometimes recommended for optimal balance with a facelift. The key is to maintain a natural look, and each surgeon may have different approaches to achieving that harmony across your facial features.
