My forehead has changed with age I am 28 now and have noticed it appears sunken in on the sides. How do I change this? (Photos)

Dear lagirlrhino,
it is hard to tell for sure without an examination. Generally speaking, you can get great results with dermal fillers. If you are considering a treatment, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

the celebrity you are showing has a lot of fillers on her cheeks, chin, jawline angle, temples, and lips.  yes you can volumize the temples with fillers. I often use Radiesse combined with bellafill there for patients to get long term improvement and/or sculptra.  Best, Dr. Emer.

Sculptra in combination with Hyaluronic Acid fillers will be the best option for you to achieve the look you desire. 

For the safest, most immediate, consistent and reversible improvement of the hollows/sunken aspect of the sides of the forehead, hyaluronic acid-based fillers would be your best option. More importantly, is finding an experienced and highly trained physician injector such as a dermatologist to treat you.

Fillers or fat transfer can be used to sculpted more prominence to the area. Properly performed Fat Transfer is will last for years to decades.

Dermal fillers can be used to add volume to the face, including the temple area.  Sculptra is one option with results lasting up to two years..  HA fillers may not last as long, depending on the filler, but results can be seen quickly.  I encourage you to meet with a board certified plastic surgeon near you to learn more.

It is hard for me to see exactly what you mean with your photos but I can talk in generality. Foreheads get more sunken in and skeletal looking with age. Sculptra is an excellent choice for long lasting results in this area .
