Dear ph7amood:Thanks for your question particularly comparing CoolSculpting to LipoDissolve!CoolSculpting (CS) is a limited but effective treatment to reduce the bulge of the muffin-top or love handle. While the skin will not "tighten", it will shrink or accommodate to the new reduced fat volume. CS can "treat to transformation". This concept is that you would continue multiple sessions of CoolSculpting up and down, and around the trunk until you are pleased. Consider that CS reduces the superficial fat under the skin up-to 20% of its thickness in limited applicator size areas. CS takes 8 or more weeks following session to see your optimized results.LipoDissolve is a injectible liquid that stimulates absorption of superficial fat. It too is limited to the area injected and can have very significant consequences such as concave irregularities, infection, cysts and abcesses particularly if not done properly. It is not an US FDA approved medicine or technique. There is a similar drug currently under testing and not yet available for under the chin named ATX-101. (See the below reference). It's off-label use will need months to years for its action and concerns to surface. I recommend you defer from the use of these injectibles at all knowing that CS is FDA approve, tried and true. Depending on the amount of fat or contouring you wish to achieve, Liposuction maybe your best approach.Please consult with a Board Certified Plastic Surgeon with experience in the treatment options available to you for your best results. I wish you all the best!Happy New Year!
