Is It Normal to Have a Vertical Neck Band at the Age of 25? (photo)

The vertical neck band in your photo is most likely the edge of your platysma muscle.  Because of your young age, the muscle probably isn't loose and saggy, but is pulling down due to muscle tension.  Therefore, Botox injections might help by relaxing the muscle.  Some people just have very active neck muscles with bands popping out due to constant muscle tension.  We usually see this in thin patients without much fat between the skin and muscle.  Surgery would be a last resort, but the platysma muscles could be partially cut horizontally to relieve the contraction and the 2 muscles than stitched together (underneath the skin) to create a smooth muscle hammock held upward.  However, I would try the nonsurgical approach first.

"Injecting soft fillers like Belotero in this area can reduce lines, wrinkles and folds as well as improve skin texture with long-term collagen production. Fillers are being used more frequently to contour and lift rather than solely line fill. Of course, fillers are best used in combination with lasers and microneedling​ with PRP to get the optimal outcome.

I suggest getting a formal evaluation with a cosmetic dermatologist to create an individualized treatment plan that works for you. Best, Dr. Emer"

There are several non-surgical treatments that may help address your concern. Therefore, it would be best to consult with a board-certified surgeon in-person as you may have more than one option.
During your consultation, the presence of banding down the front of the #neck, and, amount of excess skin and condition of your skin are among some factors which will determine the options to #rejuvenate your neck. However, chin deficiency with the neck and jawline are also taken into consideration. A weak #chin implies a lack of chin support for the skin along the neck line. As a stand-alone procedure, chin augmentation can be performed in the office under local #anesthesia. I suggest consulting with a board-certified plastic surgeon to learn if you a are indeed an #candidate and also more about the #options available and which of those may be best for you.
