Facial fat transfer is a refined way to restore youthful softness and improve contour with intention and precision. By using your body’s own fat to subtly enhance delicate facial areas, we can create smoother transitions and a more harmonious, refreshed appearance that looks completely natural. ✨

It’s amazing how combining procedures (patient also had submental liposuction) and refining features can bring harmony to your entire face. Proof that sometimes the smallest changes make the biggest impact. Curious how fat transfer could enhance your natural features?

Ear surgery (otoplasty) is a refined way to create facial balance by gently repositioning prominent ears closer to the head with precision and intention. By improving symmetry and proportion, this procedure helps the ears blend more naturally with the overall facial structure, creating a confident, harmonious look. 💫

Thoughtfully planned and expertly performed, otoplasty delivers long-lasting results while maintaining a soft, natural appearance. Sometimes, a subtle adjustment can make the most meaningful difference.
