Eyelid surgery can instantly open up the eyes for a brighter, more awake look. 👁️✨

Also known as blepharoplasty, this highly precise procedure can address excess skin, puffiness, and laxity in the upper and/or lower eyelids, helping you look less tired and more awake, while still looking like you. Whether you’re noticing hooding, under-eye bags, or heaviness that can even affect vision, eyelid surgery smooths and refines the eye area by removing or repositioning tissue for a naturally rejuvenated result.

Forehead reduction: a subtle shift that creates a more balanced, proportionate look. ✨

Also known as hairline lowering, this transformative procedure is designed for patients with a prominent forehead or higher hairline who want a more proportionate, harmonious facial appearance. By carefully advancing the scalp and lowering the hairline, we can enhance symmetry, soften facial features, and help bring the entire face into better balance, while preserving a natural-looking hairline.

Laser hair removal isn’t just about convenience, it’s about long-term strategy. 👏 Dr. Maas shares why being intentional about treatment areas matters when considering permanent hair reduction. ⁠
⁠
Common treatment areas include the legs, underarms, arms, and bikini area, but it’s important to choose areas you’re confident you won’t want hair in again. Most patients see significant reduction over time, with maintenance sessions helping refine results year after year. ✨⁠
