Thank you to everyone who joined us for our Open House last Thursday evening! 💛

It was a wonderful event celebrating Dr. Susana Ortiz, Quantum Dermatology at The Maas Clinic, and the introduction of the remarkable VECTRA 360, an advanced 3D whole-body imaging system that is transforming the way we monitor skin health.

Using sophisticated imaging technology, VECTRA 360 creates a detailed, 3D map of your skin, allowing dermatologists to track moles and skin changes over time, identify suspicious changes, and support the early detection of melanoma and other skin cancers.

If you missed our Open House, we would still love to see you! Schedule your comprehensive skin check and experience this exciting technology firsthand.

A more defined chin can make all the difference in creating a balanced facial profile. 💫

Chin augmentation with a carefully selected implant can enhance projection, improve facial proportions, and create a more sculpted appearance through the chin and jawline.

At The Maas Clinic, each procedure is tailored to your unique facial anatomy, with the goal of achieving natural-looking results that complement your existing features.

The result? A stronger, more defined profile that enhances your natural facial harmony.

Your skin changes over time. The key is knowing what’s changing. 🔎

With VECTRA 360 3D Skin Surveillance, The Maas Clinic can create a detailed baseline of your skin to help track moles and lesions over time and identify subtle changes that may warrant a closer look.

3D Skin Surveillance may be especially beneficial for patients with a personal or family history of skin cancer, numerous or atypical moles, significant sun exposure, or anyone looking to take a more proactive approach to long-term skin health.

Ready to establish your baseline? Schedule a consultation with Dr. Susana Ortiz Urda at the link below.

Individual recommendations vary. A consultation can help determine the appropriate surveillance plan for you.

Filler fatigue is real, but filler itself isn’t necessarily the problem. 💉

Dr. Corey Maas breaks down why the best results come down to thoughtful, individualized treatment: choosing the right product, placing it in the right areas, and using the right amount.

The goal should always be to enhance your natural beauty while maintaining facial balance, symmetry, and proportion, not to change what makes you look like you.
