Hello,Image Designer/Plastic Surgeon Ryutaro Natsumeis

There are various options for treating dark circles under the eyes, but liposuction is the most well-known due to advertising.
If you apply it incorrectly, it will cause hollows under the eyes.
Please see "Characteristics of People Who Fail at Non-Invasive Bear Removal (Liposuction)" for details.

The following patient developed hollows under the eyes after fat removal surgery.
The indentation creates a shadow, which causes shadowing.


As explained in the previous blog post, the negative vector type (where the eyes protrude more than the cheeks) will appear sunken if too much fat is removed.
Therefore, cases that fundamentally require the Hamra method—which moves protruding fat to hollow areas—or liposuction plus fat grafting.
This time, only fat removal was performed, resulting in hollowed-out under-eye areas.
However, it can be improved with fat grafting or baby collagen injections.
I chose baby collagen injections because fat grafting requires downtime and is scary.

Baby collagen is derived from humans, so it's highly compatible.
The effects last from six months to a year, so I think it's a good option to first try Baby Collagen to see how your skin changes after the injection, then consider fat transfer a year later.

Summary
Treatment indications for bear therapy should be carefully considered.
Bear treatment ≠ fat removal; over half of patients are not suitable candidates.
When negative vectors and tear troughs are pronounced, there is a high likelihood of post-liposuction depression, so it is advisable to avoid performing liposuction alone as the initial treatment.
However, even if the area becomes sunken after surgery, it can be improved with fat grafting or baby collagen injections.
