It's a technique that aims to just lift the brow instead of the entire face. It cane be done by itself or in combination with other facelift surgery. This is why it is so popular to be combined with others because it is a way to really rejuvenate the face and shed off those years all at once. Or I know some people that will just do a coronal brow lift in combination with Juvederm to fill in the deep wrinkles. Together they make a big impact for not a lot of money.
