In this Maas Minute, Dr. Maas explains how eyelash transplants can restore fuller, natural-looking lashes for patients experiencing thinning or gaps. ✨

Using carefully harvested hair grafts from the back of the scalp, each follicle is meticulously placed to grow like a natural lash, creating a thicker, more defined lash line. He also shares how similar transplant techniques can be used to enhance eyebrow density for patients looking to improve brow fullness.

Submental liposuction is designed to reduce excess fullness beneath the chin, helping refine and define the jawline and neck. By carefully removing targeted fat in this area, the procedure can create a smoother contour and a more balanced facial profile with natural-looking results. ✨

With a precise and thoughtful approach, this treatment enhances definition in the lower face while maintaining harmony with your natural features. Even subtle contouring can make a meaningful difference in overall facial balance.

If you’re curious whether submental liposuction may be right for you, start with a consultation. 🤍 Book your appointment at the link below.

Dr. Maas discusses how aesthetic goals evolve over time, and why the approach in your twenties should look very different from the approach in your forties and beyond. ✨

From prejuvenation with neuromodulators, skincare, and collagen-stimulating treatments early on, to surgical options like blepharoplasty or facelift procedures later in life, each decade calls for a thoughtful, individualized plan to maintain natural, balanced results.

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.
