There are many methods for performing a browlift or forehead lift including an endoscopic browlift (through tiny incisions with the assistance of telescopes) , bicoronal forehead lift (extensive incision from ear to ear across the top of the head) and a tricophytic or hairline browlift. (hidden along the hairline).  Each of these techniques achieves a similar result through the brow and the forehead in terms of smoothing of lines and gentle elevation of the brows. 

The key difference is in how they affect your hairline. The Bicoronal (ear to ear) browlift elevates or pulls your hairline back, raising the frontal hairline by up to one inch. The Endoscopic lift has minimal effect of the position of the hairline.  The tricophytic or hairline browlift can be used to adjust the hairline, usually lowering it to address a receding hairline or widow's peaks in the temporal hairline.
