Is 2nd time around chin lipo a good idea?

So if submenbtal fat is your problem then i don't see why not. Usually liposuction prevents fat stores accumulating in the same place again but if it has re accumulated then just like last time, it should work well for you again. Platysma will have less elastic to it though so don't expect the effect to be as profound. Hope that helps. Adam Goodwin 

Maybe?? But no posted photos so really can not advise. Best to seek a few in person opinions from boarded surgeons in your area.

More important than statistics are your individual skin and tissue quality when considering chin and neck liposuction.  Depending on the quality and elasticity of your skin, amount of loose skin present, and amount of fat to be removed, you may be a candidate for neck lifting as opposed to isolated liposuction.  Consult with an experienced plastic surgeon or facial plastic surgeon to discuss your treatment options.  Good luck!

 Hi, non smiling photos of your face from the front and side would help in the evaluation.  The question is whether our not excess fat in the neck is the only cause or is there some excess skin and lax platysma...are "jowls" present in the lower face.  These all effect what type of procedure would be the most beneficial.  Liposuction alone is likely to result in "more" loose skin in patients over 40 years of age and for that reason are usually combined with some skin removal procedure (Neck lift and lower facelift).
  I have performed many facial shaping procedures using dermal fillers, silastic facial implants (cheek implants, chin implants, lip implants), liposuction, neck lifts and/or facelifts for over 30 years.  
  Following my beauty principles, women look the most feminine, youthful and attractive with heart shaped faces.  Heart shaped faces have cheeks that are full and round in the front.  Cheek augmentation with a dermal filler or using cheek implants for a permanent enhancement will create full, round cheeks that will feminize the entire face.
 When evaluating the neck, if the chin is weak it creates an imbalance making the nose appear larger, the mid face top heavy and the lower face look short that de-emphasizes the lips and allows early formation of a double chin.  Chin augmentation using a chin implant will add projection to the chin creating harmony and balance to the lower face.   I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick and highly effective.
 If you have "jowls” these are sagging facial tissues and the main indication for some form of a SMAS facelift.  The underlying SMAS layer, of the face, must be dissected, lifted, trimmed and re-sutured (not merely folded or suspended with threads or sutures that will not last).  The excess skin is then removed and the facelift incisions closed.
My most popular facelift is the minimally invasive, short incision facelift that has all the benefits of more invasive facelifts (traditional, mid-face, deep plane, cheek lift and subperiosteal facelifts) but with these added benefits:
very small incisions and no incisions extend or are placed within the hair.
minimal tissue dissection = less bruising and swelling = rapid recovery ( several days instead of weeks or months with the more invasive type facelifts mentioned)
can be performed in 90 minutes or less, with or without general anesthesia
no incisions within the hair = no hair loss
excess fat can be removed from the face and neck
excess skin removed from the face and neck
cheeks, chin and jaw line can be augmented with dermal fillers (I prefer Restylane Lyft) or facial implants
most patients fly back home to parts all over the world in as little as 3 days post-op
I combine facial shaping with every facelift procedure.  When jowls are present, these should be done in concert and not alone or separately in order to create a naturally, more attractive face.
 Along with the minimally, invasive SMAS facelift described above, some of the excess skin below the chin can be removed using a small, curved incision under the chin.  This along with skin removed in front and behind the ear will tend to reduce the skin excess by around 70% or more.  However, if anterior platysma bands are present or the maximal amount of neck skin is to be removed, a "formal" neck lift can be done.  In this procedure, the face and neck tissues are elevated using a curved incision around the front (explained later) of the ear that continues in the crease behind the ear and then 3 inches into the posterior hairline.  The tissue is dissected from that point all the way across the entire neck to the same position on the other side of the head in a dissection that is as long vertically as the entire neck.  The Platysma muscles are tightened using a curved incision under the chin and each side is pulled upward and back again being tightened at a line behind each ear (under the tissues).  Since the skin flap pull is up and back, this will pick up any tissue laxity along the jaw line or "jowls" which must be dissected and flattened out using a lower facelift (incision around the front of the ears).  If this isn't done, pleats of excess skin will appear below each ear.  This is an extensive surgery taking 4 1/2 to 5 hours with large incisions, possible hair loss and months of recovery.  In my experience, most men opt not to have the telltale signs of this type of surgery since they can't cover them with long hair.
Hope this helps.

Hi there, 

Thank you for the inquiry. Without a picture, it would be hard to say if a secondary neck liposuction procedure can achieve more definition in your jaw and chin area. If you have excessive loose skin, then you may benefit from a neck lift procedure. I recommend an in-person evaluation with a certified, and experienced facial cosmetic plastic surgeon to determine whether or not you are an ideal candidate based on your skin quality and extend of aging present in the neck.

Hope this helps!
