Can it give to over 65 person? After Kybella, do we need surgery to remove skin sag?

The short answer is, yes.  You can give Kybella to a person over 65 years old provided they are a good candidate for the procedure.  Ideally, a patient treated with Kybella would NOT need surgery to remove sagging skin.  This is why it is extremely important you see a medical professional, like a plastic surgeon, who is experienced in facial aesthetics and facial anatomy.  With Kybella, we rely on the elasticity of the skin to retract as the fat beneath it is dissolved.  If an older (and some younger) individual has poor skin elasticity, then they will develop loose hanging skin after being treated with Kybella.  The only way to fix that skin would be with a surgical procedure.   Best of luck!

A good candidate for kybella may be over the age of 65.  A good candidate is someone with submental fullness due to excess fatty tissue.  Kybella does also tighten the skin modestly.  As we age, our skin and neck muscles are more prone to sagging.  This can happen before age 65, but becomes more common with increasing age.  So, some people over age 65 are good candidates, and some people under age 65 are not.  The consultation is the key.  An experienced provider should be able to point you in the right direction.

In theory, if you have a moderate degree of neck laxity with submental fullness, you can be a candidate for Kybella, regardless of whether you are older than 65 or not.  With age, we do get more laxity everywhere, but it does differ from one individual to another.  I would visit with a board certified plastic surgeon in your area to discuss whether Kybella is an option for you.
