Will professional microcurrent treatments help masseter regain volume after Botox?

The best combination treatment for the jaw area is a combination of skin tightening and volume in the jaw area.  I would suggest Thermage FLX to help best with skin tightening as the new technology heats the skin more efficiently and tightens the skin.  Volume in the jaw line can be accomplished with Restylane, Juvederm, or Sculptra depending on the skin texture and laxity.  Please consult an expert in skin rejuvenation for the best cosmetic results.
