Can I Use Dermal Fillers if I'm Prone to Keloids?

Keloid scars are thick, raised, irritated scars that are usually associated with a surgical incision or a traumatic laceration. The ear is the most common body-part to form a keloid, and keloids are more common in patients with darker skin-types.

Although keloids can form from ear-piercings, I am not aware of keloid formation after a brief needle puncture.

I hope this is helpful for you.

That depends on how prone you are. If it was me I am not sure I would be willing to take that chance. If it works that's great but if you get the keloid it can be very difficult to treat. It would be different if the undesired result were easier to treat/cure.
