Pain from the procedure is described as minimal to moderate and swelling and bruising does occur also.  Of course pain tolerance is different from one person to another.  Usually healing occurs between 5 to 10 days.
If you ask one person on a scale of one (1) to ten (10) what is your pain like?  They might say a five (5).  Another individual might describe that same pain as a nine (9).   Discuss your pain tolerance with your plastic surgeon and find out what the doctors previous patients also said.  The incisions made will probably be sutured so they will have to be taken out too.  So the results of a brow lift have to be weighed.  Do you want to sacrifice time and pain for a better looking less tired look, or do you want to forgo the procedure and keep your current look.
The Coronal lift is still used for eyebrow lifting, but seems to be a more traumatic surgery, since the cut is made across the forehead, either at or behind the hairline from ear to ear. The numbness may be more pronounced since less care is taken to avoid the nerves. One or two Centimeters of skin is removed from the top of the forehead and then sown together to give the eyebrows its lifted look.  Also the muscles are manipulated to give a better look.  Bruising and swelling still takes place.

Ask your Surgeon
Your plastic surgeon might give you some pointers for before and after your endoscopic lift.  For instance you might be told what medications you should avoid and which ones to take.  You should ask if there might be any severe bruising after the surgery and will there be any bandaging present.   Find out when you need to come back for consultation and when you can take off any bandages that were applied.   Ask about the swelling and if an ice pack will help or relieve the pain.  Do you need to rest or do you need to keep a moderately active lifestyle?   Your muscles in your face are used for so many expressions.  It is easy to forget that we use them so often.  Expressing your self in the usual manner may be a little painful and any extreme laughing may not be advised.

Always get two or three opinions about any surgery.  You should be informed to the best of your ability and ask many questions.  Pick a qualified surgeon who is successful and has your best interests at heart.  Don’t be pushed into any surgery, gather your information and discuss it with your family or friends.  The bruising, swelling and pain may be a minor nuisance to a beautiful set of eyes.
