Scarring from direct brow lift

I am considering getting a direct brow lift that is where the incision is made directly above the eye brow to lift the brows. I’ve read that if the incision is made at the glabella end of the brow this can result in more noticeable scarring than if the incision is made in the lateral part of the brow. My question is: how far from the glabella end of the brow should the incision commence to avoid risking noticeable scarring?
