Lipolysis injections for double chins are effective in reducing double chins, but the exact results vary from person to person. Lipolysis injections dissolve and eliminate fat cells in the injected area, and once the targeted fat cells are eliminated from the body, the fat is no longer stored in the chin area, resulting in a reduction of adipose tissue and improvement in the appearance of the double chin. The results are usually seen in one injection, two are more noticeable, and three act as a consolidation, with the course of treatment usually lasting 4 to 6 weeks. Lipolysis injections eliminate fat, not water, and usually provide some therapeutic effect to improve the appearance. However, its effect varies from person to person and cannot be generalized. Be careful not to wash your face for 24 hours after lipolysis injection, do not use cosmetics, and do not apply topical medications around the injection. If there is any discomfort after lipolysis injection, you need to go to the regular hospital in time to avoid delaying your condition.
