Under eye hollowness or sunken eyes is a common sign of aging that occurs when the fat and collagen that normally keep the under eye area looking plump begin to diminish. 

There are several derma-based treatments that can be used to treat under eye hollowness, including:

Dermal fillers: Hyaluronic acid-based fillers, such as Restylane and Juvederm, can be injected into the under eye area to add volume and improve the appearance of hollows. The results of dermal fillers typically last six to nine months.

Platelet-rich plasma (PRP) therapy: PRP therapy involves injecting a patient’s own blood plasma, which is rich in growth factors, into the under eye area. This can help to stimulate collagen production and improve the appearance of under eye hollowness.

Micro-needling: Micro-needling involves using tiny needles to create controlled micro-injuries in the skin, which can stimulate collagen production and improve the appearance of under eye hollowness.
