I'm slim everywhere else, but the skin under my chin is sagging so much that I end up with a double chin every time I take a photo.

Contouring injections have their limits, so I'm looking into equipment-based lifting.

Since I work, severe bruising is a problem, so I'm looking for a place that performs procedures well to tighten the skin seamlessly without leaving visible marks.

It's difficult for me to travel far, so please recommend a dermatology clinic in Yongin with skilled technicians.
