Dr. Corey Maas breaks down one of the biggest misconceptions about rhinoplasty: it’s not about making your nose as small as possible, it’s about proportion. 👃✨

Follow along as he explains how features like your upper-lip length and the space between the inner corners of your eyes help determine ideal nose projection and width.

Curious whether rhinoplasty could enhance your proportions? Book a consultation at the link below to talk through your goals. ✨

Thread lift: refined lift, refreshed contours! ✨

This minimally invasive treatment uses dissolvable threads to gently lift, reposition, and support the skin, perfect for improving mild to moderate sagging in areas like the cheeks, jawline, and lower face. By enhancing definition and restoring youthful structure, a thread lift creates a naturally elevated look without adding volume or requiring surgery.

It’s amazing how a subtle lift can rejuvenate the entire face, showing that small, precise changes make the biggest impact. Book your consultation with us at the link below.

Neck lift: subtle refinement, striking results! 💫

This procedure tightens and smooths the skin along the neck and jawline, addressing sagging, banding, and loose skin that can appear with age or weight changes. By restoring definition and harmony to the lower face, a neck lift helps you look refreshed, not “done”, just naturally rejuvenated.

It’s incredible how refining the neck can elevate your entire profile, proving that true transformation lies in the details. Book your consultation with us at the link below.
