A crisp neckline is a major determinant of attractiveness. Pick at any attractive person and look at their neck line. Chances are they have a crisp neck line. In our teens, the neck line is crisp and tight. In the twenties, some fat accumulates centrally under the chin but the skin is still tight. In the thirties, the fatty pat can enlarge but the beginnings of laxity sets. In the forties, the skin of the neck and chin thins and the deep fatty deposits enlarge. This is when a double chin becomes noticeable. With aging, fat accumulates under the skin of the chin, called pre-platysmal fat. Liposuction is the main treatment for this fatty deposit. As the fatty deposit enlarges with age, it can cause skin laxity, i.e., a turkey neck. Recently, the FDA approved a drug called Kybella. The active ingredient is deoxycholic acid (DC). The DC is injected into the fatty area of the neck and it disrupts the fatty cell membranes, causing destruction of the fat. Your body then clears the debris from the area. The session takes 15 minutes and it is repeated at least 2-3 times, at monthly intervals. The fat destroyed should not return. The injections can burn a bit during the procedure but it is very tolerable. The procedure costs $2500 for the first two sessions, which should give lasting results. However, in some patients more monthly sessions might be needed. This procedure is a great alternative for those who do not want to undergo liposuction. This is a great tool in the hands of your cosmetic surgeons. Now we can use injectables like Botox to relax muscles that cause wrinkles and even lift. This is a powerful tool when combined with fillers that can enhance structures, reducing wrinkles and enlarging structures like the cheek or chin. Kybella is going to give your physician an even greater power to now shrink areas, like the double chin. This is an exciting time in cosmetic dermatology.
