Treatment options for platysma bands and neck laxity - 52kg 31 year old female (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 submitting your question and photos. A combination of Botox and RF microneedling treatments are excellent solutions to improve skin laxity and reduce the appearance of the platysma bands you’re referring to.
When injected directly into the neck bands, Botox can reduce activity of the platysma muscle to smooth away the horizontal banding. RF microneedling increases the body’s elastin and collagen production, allowing the skin to grow tighter, firmer, and smoother over the course of several weeks. I recommend scheduling an in-person consultation with an experienced, board-certified facial plastic surgeon and injector. They will be able to determine the best treatment options to help you achieve your aesthetic goals.

Based on what can be evaluated in your photos your main issue is the platisma bands and minimum saggy skin.
Botox will be the ideal treatment in each of the bands.
Be encouraged.
