They use endotines. In case of coronal incision, browlift can be done with or without endotines. It's just surgeons personal preference. It's little harder to achieve desired browlift effect with coronal incision, and this is a reason why some surgeons use endotines.
In case of hairline incision, endotines generally aren't used, unless if a hairline is very receded and a lot further back.
There is no difference to browlift effect with hairline or coronal incision.
