Hi,Absolutely! Morpheus8 and PDO threads combination therapy will cause effective skin tightening. The only this is that, you will have to complete the three sessions of Morpheus8 (monthly x3) before you can add PDO threads. Both treatment have the ability to make new collagen (PDO threads) and Morpheus8 stimulates collagen to cause skin tightening. Looking at your pic, it appears that the kybella did shrink the fat under the chin and you certainly need skin tightening to tame down the sagging skin. Morpheus8 upon completing the three sessions will improve your skin laxity, On the other hand, threads result is immediate, but you will need to repeat again by 3 months for longer duration (can last up to 2 years or more). Find a provider who does Morpheus8 or threading, get consultation and ask your questions before the treatment.
