I had an extremely rapid weightloss and my face looks sunken & saggy. What are the main areas treated for this? (Photos)

Hello,
Thanks for your question!
 
According to your pictures you will have good results with combined
treatment protocol including dermafillers, Botulin toxin, and eventually peeling
and biorevitalization and skin care.
My approach is to treat the face as a whole unit and focus
and highlighted which areas of the face need to be prioritised and treated
by placing the appropriate dose of product (fillers) in right
area in order to restore the volume lost and achieve a lifting and natural
looking effect. It is indicated for patients who want to look less tired, less
saggy, more youthful and “fresh” with natural results. 
In addition this medical approach is suitable for top up during
the years and with minimal downtime.
I would strongly recommend to seek the advice of an expert doctor
with extensive knowledge of the facial anatomy and aging process and experience
in facial assessment and treatment.
 Hope this help,
Best Wishes,
Dr Giuseppe Fiore, MD

You will have the best results from a combination of treatments.  Fillers can be used to help add lost volume to the eyes and cheeks.  They can lessen the laugh lines around the mouth.  You can combine this with other treatments such as FaceTite with Morhpeus8 treatments to tighten the skin overall.  Visit with a board certified plastic surgeon near you to learn more.
