Will a sunken temple on your face go away once you gain weight? (Photos)

Ron,
Unfortunately, our bodies store weight in different areas of the body preferentially. For most, weight is stored around the waist before the face. However, if enough weight is gained, you will see improvement in facial fullness. With that being said, the amount of fullness seen may not be enough to resolve sunken temples. Fillers and implants have been two methods of rejuvenation to the temples. Consulting with an experienced aesthetic surgeon is recommended to determine the right treatment plan for you.

Gaining weight will certainly help with facial volume loss. However, a filler will expedite the process. I recommend that you consider Sculptra Aesthetic which is a volumizing facial filler that works by stimulating your skin to produce more of its own collagen.
