Voluma can be used to create volume and contour in the cheeks. Kybella is good for fat under the chin and won't make the jowls appear larger. Kybella take 1-3 treatments every 6 weeks. Patient will develop swelling and possible bruising after each injection that may last a few days. The benefit of Kybella is each treatment is quick and completed in the office. However, some patients need more than one treatment to get desired results. Hope this helps.
Thank you for your photo. Voluma is derived from hyaluronic acid which is a moisturizer found naturally in your body. Voluma is generally used for areas such as nasolabial folds and cheeks. Kybella is an injectable product that can be used to help your body to rid itself of fat cells that form under the chin (submental fat). It would be a good option to help reduce your double chin. For more information, I recommend getting a in person consultation with a board-certified dermatologist.
