Lower face laxity at 30 - is anything that will give a noticeably dramatic improvement? (photos)

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

Thank you for your question and photos. You may be a candidate for a chin implant to define the jawline and create a striking, natural-looking contour. A chin that appears too small compared to the other facial features can amplify sagging skin on the neck and along the jawline.
With a custom-fit chin implant, the facial proportions can be brought into balance and the laxity improved for a noticeable result. I recommend scheduling an in-person consultation with an experienced, board-certified facial plastic surgeon. They will be able to conduct a thorough physical examination to determine what procedure may yield the best results for you.

It looks like you have a somewhat recessive chin and submental fullness. I would recommend a consult for a chin implant and jawline liposuction. It appears that you have an overbite which is another indication that your chin may be recessive.
