What is the best smooth filler to fill the gaps between “snakes like” botched temple threads?

Infections, thread extrusion, abnormal skin sensations, short duration of benefits, and skin dimpling, as in this case. are among the known and fairly common complications of threadlifting, which is why I gave up threadlifts over two decades ago when the last threadlifting fad hype was going on. Belotero Balance, a hyaluronic acid filler, may be placed superficially to elevate and smooth these "snake-like" indentations. However, due to the vasculature in the area, this must be done with great caution and by an experienced physician injector. Hope this helps.
