Trying to get a more symmetrical look (Photo)

Your age, 28, is not a limiting factor for a facelift, as facial changes depend less on age and more on factors like gravity, genetics, and your skin’s natural characteristics. Some people may experience early signs of sagging or asymmetry regardless of age.
For your concern about a weak chin and early sagging, submental liposuction (under-chin fat removal) combined with jawline contouring can help create a more defined and natural-looking lower face and profile. This procedure enhances the jawline, giving your face a stronger and more balanced appearance.
If you feel your face looks wider or more square due to prominent masseter muscles (the chewing muscles at the jaw angle), Botox injections to the masseter muscle can slim the lower face and soften your jawline.
To address facial asymmetry, dermal fillers can provide temporary improvement, but for a more natural and longer-lasting result, fat grafting (fat injections) is recommended. This technique adds volume using your own fat, improving both symmetry and skin quality.
Overall, a combination of these treatments may offer the best outcome to enhance your facial symmetry and profile. However, a physical examination is essential to create a personalized treatment plan that suits your unique facial anatomy and aesthetic goals.

Thank you for your question and sharing your photographs.

There are a combination of elements in the lower face that you could contemplate along the lines of your concerns.

The volume under the chin is effectively a hereditary feature and can be addressed by a deep plane anterior necklift intervention which deals with the volume muscles. This produces increased definition for the jawline, the impression that the chin is more projected and that the neck has slender contours throughout.

In the photos from the frond the right side of the jaw appears squarer. This suggests hyperactivity of the muscles during sleep (bruxism) and can be addressed with botulinum toxin injections. The botulinum toxin injections in particular on the right side are likely to produce a levelling of the contours with the left since the central part of the jaw has more symmetry. It allows you also to produce a slimmer contour for the lower face which typically emphasises the appearance of the eyes.

I would recommend you to have facial contouring(square jaw) surgery to achieve a slimmer, more defined jawline and it also can improve your asymmetrical. According to your photos & age, you probably don't need facial lifting right now, you can decide facial lifting later.
