What to expect in terms of costs, recovery, and results with a pretrichial browlift?

So I would like to get a browlift since my eyebrows are a bit droopy and it gives me a tired appearance. I searched the web and found out the most common method tends to make the hairline move up. For me this immediately eliminates this option as I already have pretty large forehead. So I would like to know about the pretrichial method. I tend to scar pretty well but swell like crazy. What can I expect with this procedure? And what is the average cost? Thank you!
