One week after Kybella, neck red and itchy, is this linked? (photos)

It can take several weeks for swelling and/or redness to resolve. However, I recommend following up with your Doctor about your concerns. Kybella takes 1-3 treatments every 6 weeks to get desired results. The benefit of Kybella is each treatment is quick and completed in the office. Most patients need more than one treatment to get desired results. 
Hope this helps.

Redness and swelling can be typical after Kybella and can take several weeks to resolve. Swelling can be improved with venus legacy and lymphatic massage. I recommend following up with your practitioner for after care. It can take 6-8 weeks to start to see results with Kybella. To improve Kybella results, I recommend a combination approach with thermage, ultherapy, exilis. VASER liposuction in combination with ThermiRF is an alternative for contouring the chin, if you're a candidate. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer
