Flabby Wrinkly Neck After Losing Weight, How Can I Fix It?

Thank you for  your question.  Congratulation for your weigh loss, now you also need to be prepared with the changes that your body and face will suffer as consequence for you weigh loss.  In your face the nasolabial folds will become more prominent and also your cheeks are going to lose volume.  In  your neck the skin is gong to be loser and you might have platysma muscle band more expose the massage will not help this condition

Hi,
Weight gain and then loss will  cause loss of elasticity in your neck as well as facial volume and skin.  Over the counter home remedies do not help tighten the skin of the neck to any significant degree.  Even some of the devices we have such as laser, radio frequency, chemical peel are not all that helpful. 
But a neck lift or lower facelift will work very well to remove the excess skin, tighten the neck. In addition, V line can be restored and neck bands, turkey neck waddle, neck bands and jowl can be fixed. The down time is only about a week.  
I hope that helps.  

Congratulations on the weight loss! The neck can have horizontal wrinkles and wrinkly skin especially after losing weight. Genetics as well as from sun damage and aging can also play a key role and can explain why some people have a worse flabby neck appearance than others who might've also lost the same amount of weight. This area can be very bothersome to patients.Surgical treatment with possibly a neck lift and short scar facelift is the best way to get rid of them but this will leave scars which some people don’t want.There are several nonsurgical options to consider. Some can be done at the same time. Surgery combined with Botox and filler injections, laser treatments and chemical peels before or after surgery are all good options.  These procedures can be done safely in the office and the results are often very satisfying. An in-office private consultation and examination with a board-certified plastic surgeon would be the best way to fully  address your specific concerns and determine the right treatment plan. I would recommend that you see a board-certified plastic surgeon in your area that is a member of both ASPS & ASAPS and performs a lot of facelifts & neck lifts but also offers all the nonsurgical options such as injectables and laser treatments. Go over your concerns with them and make sure above all, you walk out of there with several options and an idea of the pros and cons to each of them as well as realistic expectations.
